    .exe executing after final command.

    Hello - first post here - hopefully someone can help

    Im fairly new to C++, I've got MS Visual and I was experimenting the other day and came across a problem.

    I found a simple script and entered it into MS Visual.

    PHP Code:

    #include <iostream>
    using namespace std;

    void main()
    {

    int min=0max=0i=0;

    cout << "Input your first number to count from: ";

    cin >> min;

    cout << "Input your last number to count to: ";

    cin >> max;

    for(
    i=min<= maxi++)
    {
    cout << << endl;
    }


    So I entered that into MS VIsual, Complied it and found the finished product.

    I opened the .exe and the black screen appeared.

    It asked me for the first number - I entered it

    It asked me for the second number - I entered it

    Then as soon as I have pressed return it showed me the numbers inbetween for about 0.1 of a second and shut down.

    I know that after I press return it should say "press any key to continue" On mine - it doesnt.

    So basically does anyone know why is executes after that command, and how I can fix it...

    By the way I have tried with more than one script and it always shuts down at the end.

    Thanks in advance

    Mark

    You need to hold the screen to show the results.

    getchar();

    Inbetween the } and the } should be a return 0;

    Not since he's using void main()

    Hi - thanks for the quick reply.

    I entered the return 0;

    the script still executes.....

    Subdene - what does getchar(); do and where shall I enter it?

    Thanks

    That one I can't tell you because I never use it (never works for me), but you put that were you want the user to press a key. But if your doing console programming, just use cin >>.
    [EDIT]For input, try using char. Do it like this instead of int:
    Code:
    char i[10];
    and do it that way

    PHP Code:
    #include <conio.h>
    #include <stdio.h>
    #include <stdlib.h>
    #include <iostream>
    using namespace std;

    void main(int argcchar *argv[])
    {

    char min[20], max[20], i[20];

    cout << "Input your first number to count from: ";

    cin >> min;

    cout << "Input your last number to count to: ";

    cin >> max;

    for(
    i=min<= maxi++)
    {
    cout << << endl;
    }
    system("pause");
    return 
    0;

    That should work.

    If you are using the ansi standard there should be no ".h" after the header file. That should sort it out.
