    recursive formulas with arrays

    Hi, I'm trying to make a program that prints the first 100 numbers of cont, using the recursive function listed below. Unfortunately, what I wrote doesn't work, so I was wondering, if it was even possible to do this.

    Code:
    #include <stdio.h>
    int main()
    {
        int cont[100],n;
    
        cont[n]=(n+1);
        for(n=1;cont<=100;n++)
        {
            printf("%s", cont);
        }
    }
    Thanks

    You seem to not know what recursion is. All you have is a loop. A recursive function is a function that calls itself. Like so:
    Code:
    void foo( int x )
    {
        if ( x < 10 )
            foo( --x );
        else
            printf("x is %d\n", x );
    }

    Okay, several problems here:

    1) There is nothing recursive about that code whatsoever.
    2) You're using n uninitialized
    3) Your cont array doesn't actually contain anything meaningful.
    4) The %s specifier for printf() expects the passed argument to be a string. cont is not a string.
    If you understand what you're doing, you're not learning anything.

    5) I have no idea what the hell that foo function is supposed to do. I blame tequila.

    It's supposed to be a very long loop if x is less than 10.
