Why this is 41?

Question

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

int main() {
cout<< rand();
return 0;
}
//* output
41
*//

Answer 1

rand() is a pseudo-random function, and uses a seed to generate different secuences... if the seed is the same, the output of the rand() function will be the same.

in order to have a seemingly random output, you must set the seed to a different value every time you run the program.

you can achieve this with srand() and time()
Just add this line before the cout

srand(time(NULL));

and it should work as expected.
