What is the purpose of your program?

Here is an example of pseudo random number generation:

#include<iostream>
#include<cstdlib>
#include<ctime> 

using namespace std;

int main()
{
    int randomNumber;

    srand(time(NULL)); 

    for (int i = 0; i < 50; i++)
    {
        randomNumber = rand() % 100 + 1;
        cout << randomNumber << '\n';
    }
} 

This will output 50 random numbers between 0 and 100.
time.h is from c, to use it in c++ you can include it the way you did but the preferred way is using it's new name ctime. Check out this link about srand( ): http://www.cplusplus.com/reference/clibrary/cstdlib/srand/
