    Unhappy Formatting Arrays

    I'm practicing printing some arrays and I am having trouble figuring out how to properly print one out. I have attached the assignment I am working on. I have solutions to the problems, but when I try to check my work and print out the arrays I can't get the formatting right.

    Here is what I have for 2)

    #include <stdio.h>
    #include <stdlib.h>
    int main(void) {
        int i, square[ 5 ] [ 5 ] = { 0 };
        for ( i = 0; i < 5; i++) {
          for ( i = 0; i < 5; i++) {
            square[ i ] [ i ] = ( i + 1 ) * ( i + 1 );               
            printf("%d", square[ i ] [ i ] );
        return 0;

    The output comes out in 1 single line instead of as a square. I thought the printf("\n"); inside the rows loop would fix the issue, but I think the issue might have something to do with the square array not being completely populated in the calculation sequence. I thought that the values not entered in that step would automatically just be zero or empty.

    Please help/offer input. Thanks

    Write out on paper a 2d array and step through the process of your nested for loop to see exactly where you are going wrong. Hint: You need to index your rows and columns with separate variables.
