I assume you mean by using the run time function rand()

Code: [Select]


for(int i = 0; i<16; i++)
{
    printf("%d\n", rand());
}

Or you can use a modulo for limiting output to a specified range.

for(int i = 0; i<16; i++)
{
    printf("%hhd\n", (char)(rand()%256));
}


One can also seed the pseudo-random number generator before using it.

srand(GetTickCount());

or

srand(1234);
