Random numbers in C

Question

for(i = 0; i < n; i++){
        srand(time(NULL));
        printf(\"%d \", time(NULL));
        for(j = 0; j < (n-1); j++){
            a[i][j] = rand();
              


        

Answer 1

int** a;
int i;
printf("Enter array size: ");
scanf("%d", &n);
if( n < 1 ){
    printf("Size should be > 0\n\n");
    return NULL;
}
a = (int**)calloc(n, sizeof(int));
for(i = 0; i < n; i++)
    a[i] = (int*)calloc(n-1, sizeof(int));

Here is my array...
