C++ Exercises: Generate random integers in a specific range

C++ Numbers: Exercise-8 with Solution

Write a program in C++ to generate random integers in a specific range.

Pictorial Presentation:

Sample Solution:

C++ Code :

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

using namespace std;

int main() 
{
int ln,un;
 cout << "\n\n Generate random integer in a specific range: \n";
 cout << " --------------------------------------------------\n";
cout << " Input the lower range of number: ";
cin >> ln;
cout << " Input the upper range of number: ";
cin >> un;
     srand(time(NULL));
     cout<<" The random number between "<<ln<<" and "<<un<<" is: ";
cout <<  ln+rand() % static_cast<int>(un-ln+1) << endl;     
     return 0;

}

Sample Output:

Generate random integer in a specific range:                          
 --------------------------------------------------                    
 Input the lower range of number: 15                                   
 Input the upper range of number: 25                                   
 The random number between 15 and 25 is: 18
