What's wrong?

Question

Lesson 40.2. Why when is coming the second number the result isn't changed.

#include <iostream>
#include <cstdlib>
using namespace std;

int main() {
srand(0);
int range;
cin >> range;
//
for (range=0; range<4;range++){
cout<<1+(rand()%4);

}

return 0;
}

Answer 1

because rand makes random numbers between 0 to a maximum and srand makes that number compeletly random and if you call rand without passing a diffrent number to srand you will give same numbers which are random between 0 to maximum but are same

Answer 2

the maximum number located at RAND_MAX and if you want to have real diffrent numbers you should pass the time value to the srand
