Reading in characters

[Wynd]

I want to write a program that opens a file with ifstream and reads each character in the file and prints it out. This is what I have so far:

#include <fstream>
#include <iostream>
using namespace std;

int main()
{
    char a;
    ifstream fin;

    fin.open("test.txt");
    fin >> num;
    cout << num; // Works OK

    while (!fin.eof()) // ?
    {
        // What goes in here?
    }
    fin.close();

    return 0;
}

Not sure where your 'num' name is coming from... but anyway fstream works like cin for the most part... you would most likly need a deliminating character between each char input... or you could simply create a character array... then fin to the array.. then you can use each character individually... but it will end input to the array when a space of CR is reached.

char a[256];//or however big you need it


fin >> char ;

cout<< char[0];
cout<<char[1];

ect...

or use a loop to do the same.

Sorry, it used to be 'char num' but I changed it. What's a space of CR?

I think he means newline = \n

you can also do this:

char ch;

while(the_file.get(ch))
        cout << ch;

or make a 2-dimensional char array....

char info[100][20];

for(int i=0;i<500;i++)
the_file >> info[i];
