Neverside

I would suggest: cplusplus.org as a place to get immediate understanding.

after reading your post, i assume you want the program to quit only after you input "end" at the console, and it will ask input over and over if you input other than "end".
this is the snippet:

Code:

main function {
    boolean proceedProgram = true;
    string consoleInput;

    while proceedProgram == true {
        cin>>input;
        if input == "end" {
            proceedProgram = false;
        }
    }
    return 0
}

note: dont forget to include the standard c++ string library if you want to use string. never use char*, it's C way not C++ way.

Quote:

when i hit enter it prints "and double value is" etc. but it instantly exits the program. i removed the return 0; so why does it still do this?

never remove the return 0; statement. the entry point of a C++ program is "int main()" which means the function will always have to return an int.

#include <iostream>
using namespace std;

int main ()
{
int i;
cout << "Please enter an integer value: ";
cin >> i;
cout << "The value you entered is " << i;
cout << " and its double is " << i*2 << ".\n";
cout << "\nPlease enter any character and hit enter to exit: ";

/* this section clears any errors and flushes the buffer to which cin points respectively, input buffer flushing taken from cprogramming.com */
cin.clear();
while(((i = cin.get()) != '\n') && (i != EOF));

/* this time it can error out (or not) because the program is finished */
i = cin.get();
return 0;
}

Just a note on why the cprogramming.com snippit works:
cin.get() can return a value of type int, so if you enter a single character (or a string of characters), the integer value (usually the ASCII code in Windows) of the first character is returned.
Since there are still characters in the cin buffer, they must be extracted manually, which is why you use cin.get() in a while loop. The conditions for exiting the while loop check to see if the RETURN/ENTER key is pressed ('\n') or if the file pointer is at the end of the file (EOF).

BTW, if you are wondering, the program will read up to its max value or a character that will set an error bit (the max value for int is 2147483647 usually or 32767 if int is short since it is signed by default). For example, entering 1838675309abbbbbbbbbbbbb will read 1838675309, but trying 11838675309abbbbbbbbbbbbbbb will render the default value, whatever it is.
In other words, the first integer will be stored as long as its max value is not exceeded and it does not contain any error bit setting characters. Note that normally, integer types read values modulo their max value. If an error bit is set, it will not carry out that modulo operation and will instead render its default value, so 11838675309 will allow the execution of the modulo operation whereas 11838675309a will not.
