    Two-Dimensional Array Initialization (please help)

    I am a beginnger programmer and I am trying to write a program that will initialize a 2-dimensional array with zeros. Also, it will use a function to do the intializing. Unfortunately I can't get it to work.

    Here is the code I have so far:

    Code:
    
    #include <stdio.h>
    
    #define M 10
    #define N 5
    
    void InitializeArray2D ( int array[][N], int r, int c);
                        
     
    void main() 
    {
       int a [M][N];
    
       InitializeArray2D (a,M,N);
     
    }
    
    
    void InitializeArray2D (int array [][N], int r, int c) {
    
       int i,j;
    
       for (i=0; i<r; i++){
            for (j=0; j<c; j++){
                    int array [i][j] = 0;
                            }
                    }
       printf("%d", array[1][1]); /*test to see if initialization worked*/
    }

    Any help would be greatly appreciated!!
    Thanks...
    Phil

    In your for loop, remove the "int" from in front of "array". You only need to put the type when declaring the variable.

    Also, main needs to return int, not void.

    Apart from that, it looks fine.
