Question

Write a c++ program that generates three random numbers. The first number should be between 0-30, the second number should be between 30-60 and the third number should be between 60-90.

Answer 1

#include <stdlib.h>

#include <time.h>

#include <iostream>

using namespace std;

int main() {

srand(time(NULL));

cout << rand() % 30 << endl;

cout << rand() % 30 + 30 << endl;

cout << rand() % 30 + 60 << endl;

}

Step-by-step explanation:

rand() returns a pseudo-random integral number in the range between 0 and RAND_MAX. By applying the modulo operator, you map that to the desired range (30 in your case), then you add an offset.
