Learning and doing Visual C++
Okie doked guys, so i have started......*ahem*..."Learning" about Visual C++ and I need some help from y'all about where i can find any resources and tools, PDF's, or anything that can help me learn about C++. I found a little tutorial online about making some sort of clock, anc i put the code into use, but for some reason, when i try to run the program, it exits almost immediately, and in the Debug Output box it says
Code:
'HelloWorld!.exe' (Win32): Loaded 'C:\Users\Mateusz Wierzbicki\Documents\Visual Studio 2013\Projects\HelloWorld!\Debug\HelloWorld!.exe'. Symbols loaded.
'HelloWorld!.exe' (Win32): Loaded 'C:\Windows\System32\ntdll.dll'. Symbols loaded.
'HelloWorld!.exe' (Win32): Loaded 'C:\Windows\System32\kernel32.dll'. Symbols loaded.
'HelloWorld!.exe' (Win32): Loaded 'C:\Windows\System32\KernelBase.dll'. Symbols loaded.
'HelloWorld!.exe' (Win32): Loaded 'C:\Windows\System32\msvcp120d.dll'. Symbols loaded.
'HelloWorld!.exe' (Win32): Loaded 'C:\Windows\System32\msvcr120d.dll'. Symbols loaded.
The program '[3132] HelloWorld!.exe' has exited with code 0 (0x0).
The reason it says "HelloWorld!" is because i started with that tutorial, but moved on in the same project, coz that one wasn't also functioning, giving me the same "Exited with code 0 (0x0)"
Here are the pieces of code from my other 3 Tabs of main code
TAB 1: Time in this demo.ccp
Code:
// Implementation file for Time.h
// Member function definitions for Time class.
#include <iostream>
using std::cout;
#include "time.h"
// Time constructor initializes each data member to zero.
Time::Time() {
hour = minute = second = 0;
}
// Set a new Time value using military time. Perform validity
// checks on the data values. Set invalid values to zero.
void Time::setTime(int h, int m, int s)
{
hour = (h >= 0 && h < 24) ? h : 0;
minute = (m >= 0 && m < 60) ? m : 0;
second = (s >= 0 && s < 60) ? s : 0;
}
// Print Time in military format
void Time::printMilitary()
{
cout << (hour < 10 ? "0" : "") << hour << ":" << (minute < 10 ? "0" : "") << minute;
}
// Print time in standard format
void Time::printStandard()
{
cout << ((hour == 0 || hour == 12) ? 12 : hour % 12)
<< ":" << (minute < 10 ? "0" : "") << minute
<< ":" << (second < 10 ? "0" : "") << second
<< (hour < 12 ? " AM" : " PM");
}
TAB 2: TimeDemo.ccp
Code:
// Driver for Time class
#include <iostream>
using std::cout;
using std::endl;
#include "time.h"
// Driver to test class Time
int main()
{
Time t;
// instantiate object t of class time
cout <<
"The initial military time is ";
t.printMilitary();
cout << "\nThe initial standard time is ";
t.printStandard();
t.setTime(13, 27, 6);
cout << "\n\nMilitary time after setTime is ";
t.printMilitary();
cout << "\nStandard time after setTime is ";
t.printStandard(); t.setTime(99, 99, 99);
// attempt invalid settings
cout << "\n\nAfter attempting invalid settings : \n" << "Military time : ";
t.printMilitary();
cout << "\nStandard time : ";
t.printStandard();
cout << endl;
}
TAB 3: Time.h
Code:
// Time class header file
// Member functions are defined in time.cpp
// prevent multiple inclusions of header file
#ifndef TIME1_H
#define TIME1_H
// Time abstract data type definition
class Time {
public: Time();
// constructor
void
setTime(int, int
, int);
// set hour, minute, second
void printMilitary();
// print military time format
void printStandard();
// print standard time format
private:
int hour;
// 0 - 23
int minute;
// 0-59
int second;
// 0-59
};
#endif
Thanks for the help :)

Re: Learning and doing Visual C++
For learning c++ I would suggest you look at these sites
http://www.learncpp.com/
http://www.cplusplus.com/doc/tutorial/
http://www.cprogramming.com/tutorial...al.html?mb=top
I would also suggest that you invest in a good c++ book. I can recommend some if you want.
Re: Learning and doing Visual C++
I would expect this program to exit almost immediately as it only display some info to the console screen. I've merged it all together into one module for testing
Code:
#include <iostream>
using namespace std;
class Time {
public:
Time();
void setTime(int, int , int);
void printMilitary();
void printStandard();
private:
int hour;
int minute;
int second;
};
Time::Time() : hour(0), minute(0), second(0) {}
void Time::setTime(int h, int m, int s)
{
hour = (h >= 0 && h < 24) ? h : 0;
minute = (m >= 0 && m < 60) ? m : 0;
second = (s >= 0 && s < 60) ? s : 0;
}
void Time::printMilitary()
{
cout << (hour < 10 ? "0" : "") << hour << ":" << (minute < 10 ? "0" : "") << minute;
}
void Time::printStandard()
{
cout << ((hour == 0 || hour == 12) ? 12 : hour % 12)
<< ":" << (minute < 10 ? "0" : "") << minute
<< ":" << (second < 10 ? "0" : "") << second
<< (hour < 12 ? " AM" : " PM");
}
int main()
{
Time t;
cout << "The initial military time is ";
t.printMilitary();
cout << "\nThe initial standard time is ";
t.printStandard();
t.setTime(13, 27, 6);
cout << "\n\nMilitary time after setTime is ";
t.printMilitary();
cout << "\nStandard time after setTime is ";
t.printStandard();
t.setTime(99, 99, 99);
cout << "\n\nAfter attempting invalid settings : \n" << "Military time : ";
t.printMilitary();
cout << "\nStandard time : ";
t.printStandard();
cout << endl;
}
This display so the console
Code:
The initial military time is 00:00
The initial standard time is 12:00:00 AM
Military time after setTime is 13:27
Standard time after setTime is 1:27:06 PM
After attempting invalid settings :
Military time : 00:00
Standard time : 12:00:00 AM
Re: Learning and doing Visual C++
A slightly more standard 'c++' code would be
Code:
#include <iostream>
#include <iomanip>
using namespace std;
class Time {
public:
Time(unsigned int h = 0, unsigned int m = 0, unsigned int s = 0);
void setTime(unsigned int h, unsigned int m, unsigned int s);
void printMilitary() const;
void printStandard() const;
private:
unsigned int hour;
unsigned int minute;
unsigned int second;
};
Time::Time(unsigned int h, unsigned int m, unsigned int s)
{
setTime(h, m, s);
}
void Time::setTime(unsigned int h, unsigned int m, unsigned int s)
{
hour = (h < 24) ? h : 0;
minute = (m < 60) ? m : 0;
second = (s < 60) ? s : 0;
}
void Time::printMilitary() const
{
cout << setw(2) << setfill('0') << hour << ":" << setw(2) << setfill('0') << minute;
}
void Time::printStandard() const
{
cout << ((hour == 0 || hour == 12) ? 12 : hour % 12)
<< ":" << setw(2) << setfill('0') << minute
<< ":" << setw(2) << setfill('0') << second
<< (hour < 12 ? " AM" : " PM");
}
int main()
{
Time t;
cout << "The initial military time is ";
t.printMilitary();
cout << "\nThe initial standard time is ";
t.printStandard();
t.setTime(13, 27, 6);
cout << "\n\nMilitary time after setTime is ";
t.printMilitary();
cout << "\nStandard time after setTime is ";
t.printStandard();
t.setTime(99, 99, 99);
cout << "\n\nAfter attempting invalid settings : \n" << "Military time : ";
t.printMilitary();
cout << "\nStandard time : ";
t.printStandard();
cout << endl;
}
Re: Learning and doing Visual C++
Doesn't look like 2kaud specifically said, but if you want to see the results, you should be running the program from within a command window.
If you're running it from within the IDE, which it looks like you are, then the command window will flash up and go away quickly enough you might not see it.
When running from the IDE, you can put a user input as the last last like, i.e. a "Press any key to continue..." type thing so you can see the output of the program in the window, then hit a key to continue, which will close the window.
Re: Learning and doing Visual C++
Try
before the closing } in main()
Re: Learning and doing Visual C++
Allrighty, thanks guys, that's a big help, oh, and 2kaud, i'd love it if you'd recommend some books for me. I know my dad used to own some, but they were all outdated, and gathering dust, so he threw them away, what a shame, i could've still learned from them.
However, i have this book called Cocoa Programming for Mac OS X, and inside of it, it stated that it uses C# i believe, i was wondering if C# is similar to C++. and if the format of Mac programming could be re-used/re-formatted to suit Windows programming?
Thanks

Re: Learning and doing Visual C++
Although c# has some basic similarities with c++, they are very different languages and in the main c# code is not c++ code. If you want to learn c++ then learn c++ and not try to understand c# code and convert to c++. I also would not try to use a book for Mac OS programming for Windows programming.
The current version of c++ is c++14. This is a very recent version of c++ (it was only formally agreed earlier this year) and book authors by and large haven't caught up with it yet in their book versions. However, c++14 is only a minor revision of c++11 so any book which covers c++11 will be fine. The next major c++ revision is expected in 2017.
Until you are quite familiar with c++ I would advise against any c++ book which does not cover c++11. This basically rules out any c++ book with a publishing date prior to 2012. There are several good books on advanced c++ programing published prior to this date which cover earlier versions of c++ (c++98 and c++03). Again I would caution against using these until you understand the basics of c++11. Avoid any book with a publication date prior to about 2004. These may seem tempting as they are available second hand very cheaply but the way you write code with c++11/14 is quite different to the way c++ code was written back then due to the way the language has evolved. IMO you should learn how to code 'modern c++' rather than how things were done over 10 years ago.
c++ encompasses a large standard. This can briefly be broken into
- 'c' part of c++ (basic statements, variables etc). This part of the language is very similar to the c language with some important differences
- 'c' standard library (for dealing with c-style strings, cstyle i/o etc)
- classes
- exceptions
- templates
- standard template library (STL)
- c++ i/o streams
There are basically two schools of thought as to how c++ is taught. The 'old school of teaching' basically takes the view that you learn the 'c' part of c++ first and then learn the 'extras' to c such as classes, the STL etc as separate entities of c++ which are taught as separate parts.
The 'modern' view of c++ teaching which c++ professional practitioners now say is the best way to teach c++ including the person who first developed the language - Bjarne Stroustrup (see his web site at http://www.stroustrup.com/ for further resources) - is to look at the c++ language 'in the whole' and teach all of its parts as a coherent whole.
Many books that teach c++ are written from the 'old school' perspective and IMO I would avoid these - many even have 5 star reviews!
For the books that teach c++ the 'modern' way I would suggest
Programming: Principles and Practice Using c++ 2nd edition
http://www.amazon.co.uk/Programming-...rds=stroustrup
c++ Primer 5th edition
http://www.amazon.co.uk/C-Primer-Sta...8122637&sr=1-1
c++ How To Program (Early Object Version) 9th edition
http://www.amazon.co.uk/How-Program-...1SWKVXR2TDP2QN
Once you have some familiarity with c++ I would suggest
Professional c++ 3rd edition
http://www.amazon.co.uk/Professional...8122770&sr=1-1
Effective Modern c++
http://www.amazon.co.uk/gp/product/1...ilpage_o04_s00
and the definitive c++ reference book (not one to teach c++)
The c++ Programming Language 4th edition
http://www.amazon.co.uk/C-Programmin...8122478&sr=1-3
Good luck and happy programing :wave:
Re: Learning and doing Visual C++
Allright, i'll look into it. I appreciate your help

That book will be written in Objective C. (edit: OK, it might contain some English too.)
C++, Objective C, and C# are three totally different languages. The only thing they share in common is a syntax derived from C (and in the case of Objective C, even that link is tenuous).
If you haven't done C before, my recommendation would be to learn that first, before anything else.
In my opinion object oriented languages cause more problems than they solve, though many would disagree.

Yes, I disagree. if you are going to learn c++ then learn how to do things the c++ way - not the c way and then have to unlearn and re-learn. I've come across too many so-called 'c++ programmers' who still code as if they are writing c code with a few classes thrown in. If you don't want OO then by all means learn c but IMO treat c++ and c as different languages.

Like a lot of tools, it all depends upon how they are used and that the right tool is used for the required job. Like most things, using a wrong tool for a job can result in problems.
Re: Learning and doing Visual C++
allright, so, i'll probably just focus on C++ then
Thanks guys, you're a great help
