memset an array to 1

Question

I am trying to initialize a 2d array with some integer.If I initialize the array to 0 I am getting correct results but If I use some other integer I get some random values.<

memset allows you to fill individual bytes as memory and you are trying to set integer values (maybe 4 or more bytes.) Your approach will only work on the number 0 and -1 as these are both represented in binary as 00000000 or 11111111.

The for loop isn't too much bother:

int main() {
    int i, val = 1, max = 4;
    int array[max][max];

    max = max * max;

    for(i = 0 i < max; i++) {
       array[i] = val;
    }
}
