How to generate X groups of N random numbers between min and max in C++

Answer 1

#include <iostream>
#include <ctime>
  
int getRandom(const int min, const int max) {
    return (rand() % (max - min + 1)) + min; 
}
  
int main() {
    srand(static_cast<unsigned int>(time(nullptr)));
    const int N = 7;
    const int X = 5;
  
    for (int i = 0; i < X; i++) {
        std::cout << "Group " << (i + 1) << ": ";
        for (int j = 0; j < N; j++) {
            std::cout << getRandom(1, 30) << " ";
        }
        std::cout << std::endl;
    }
}
