This is a discussion on C99 mode?? within the C Programming forums, part of the General Programming Boards category; The following code: Code: void quest_one() { char* guess; for (int a = 0; a<25; a++) { printf("\n"); } printf(QOne->Desc); ...

    C99 mode??

    The following code:
    Code:
    void quest_one()
    {
        char* guess;
        for (int a = 0; a<25; a++)
        {
            printf("\n");
        }
        printf(QOne->Desc);
        guess = getchar();
        char* answer;
        answer = "void";
        if(guess != answer)
        {
            printf("\nIncorrect, you lose!");
        }
        else if(guess == answer)
        {
            printf("congrats, you roxors!");
        }
    }
    keeps giving me the vague error of: For loop declared outside of C99 mode. What am I doing wrong?

    EDIT: Perhaps somebody could also explain what C99 mode is? I've never heard of that before

    It's giving you that error because you're delcaring a variable inside the for loop, which is not part of the C99 standard(I think).

    The way he's declaring the counter is part of C99. The OP is getting the error because he's not in C99 compatibility mode. There's some way of telling the compiler that you want to compile it with C99 standards, I'm sure. In gcc for instance, you add the option --std=c99
    If you understand what you're doing, you're not learning anything.
