    Why i can get the result print to the screen

    Hi iam new to c programming and iam trying to compile this code in Dev C ++ 4.9.9.2 and it prints the result but when i compile it works but it closes the screen and i cant see the results.

    Thanks for your help


    Code:
    // Description: will ask the user for 2 numbers and print the even //numbers in between
    
    
    #include <stdio.h>
    int main()
    {
    int min, max, i;
    printf("Please enter the minimum number: ");
    scanf("%d", &min);
    printf("Please enter the maximum number: ");
    scanf("%d", &max);
    
    for (i=min; i<=max; i++)
    if (i%2 == 0)printf("%d\n", i);
    getchar(); // when you use Dev c ++
        return 0;
    }

    when I changed "getchar()" with a "getch()" or "scanf("%d");" your program waited after printing the result

    Code:
    system("PAUSE");
    return 0;
    Try adding that line and removing the last getchar() line.

    That's just your compiler. The second is blatantly incorrect, because you have no variable to scan into. You must have one, or use the "skip" specifier for scanf. The function getchar is an ANSI standard function, and should work on any compiler. The function getch is NOT a standard function, and only works on some compilers.

    There is a FAQ on the topic. Actually there are two of them.

    What were you referring to with this comment?

    [EDIT]

    Nevermind, I assume you were directing the comment at mass.

    Which is why I mentioned scanf specifically in my reply.
