c - How to print the array?

int main() {  
  int my array[3][3] =
    10, 23, 42,    
    1, 654, 0,  
    40652, 22, 0  
  };  

  printf("%d
", my_array[3][3]);  
  return 0;
}

I am not able to get the array to print.. Any ideas why? I am a beginning programmer so any words of advice are appreciated.

What you are doing is printing the value in the array at spot [3][3], which is invalid for a 3by3 array, you need to loop over all the spots and print them.

for(int i = 0; i < 3; i++) {
    for(int j = 0; j < 3; j++) {
        printf("%d ", array[i][j]);
    }
    printf("
");
} 

This will print it in the following format

10 23 42
1 654 0
40652 22 0

if you want more exact formatting you'll have to change how the printf is formatted.
