rosijanka [135]

Answer:

#include <stdlib.h>

#include <time.h>

#include<iostream.h>

int main(void) {

   int seedVal = 0;  

   seedVal = 4;

   srand(seedVal);

  /* Solution*/

  cout<<rand() % 149 + 100<<endl;

  cout<<rand() % 149 + 100<<endl;

  return 0;

}

Explanation:

We start with the required include statements to enable use of srand, rand and time functions. I have also added iostream library to use "cout" function.

After that, the seed is initialized using srand(). And then the two rand functions are called with ranges including and between 100 and 149, and printed out.
