Problem With Strings

For some reason this code just will not work, it just repeats itself no matter what you type...

Code:

---


#include <iostream.h>
#include <stdlib.h>

int main()
{
start:
        char* pass;

        system("cls");
        cout<<"Hero Password Protection v2"<<endl;
        cout<<"Copyright (C) 2000 Hero Inc. Software"<<endl;
        cout<<"By Jake Bush"<<endl;
        cout<<"  [email protected]"<<endl;
        cout<<""<<endl;
        cout<<"Password : ";
                cin>>pass;
       
        if(pass == "hello")
        {
                system("cls");
                return 0;
        }

        goto start;
}

any suggestions?

At the time of this writing, no one has even looked at this thread. Does anyone even use C++?

couple problems with you code. First don't use gotos! Sorry about yelling like that. but in C/C++ goto are really frowned upon. Second you have a character pointer but no memory to point at. You need to actually make a character array. Third, You can't compare a string using == you should use strcmp of one of its brethren. Here is my reworking of your code:

Code:

---

#include <iostream.h>
#include <string.h>//need this for string compare
#include <stdlib.h>
int main()
{
        char pass[100];
        do
        {
       

        system("cls");
        cout<<"Hero Password Protection v2"<<endl;
        cout<<"Copyright (C) 2000 Hero Inc. Software"<<endl;
        cout<<"By Jake Bush"<<endl;
        cout<<"  [email protected]"<<endl;
        cout<<""<<endl;
        cout<<"Password : ";
        cin>>pass;
               
        }while(strcmp(pass, "hello") !=0);
    system("cls");
    return 0;
}

This is one of many many ways to do this. This is the closest to your code.

In C++, it's often easiest to use the string class from the STL (comes with VC and most other compilers). You need this:

Code:

---

#include <iostream> // NO .H!!!
#include <string>

using namespace std; // V. important

void main() {
    string A = "Hello";
    string B = "Different";

    A = A + " " + B;
    cout << A << endl;
}

---

It's not so important at this stage, but when you get to more advanced things it really helps.
