random number generator c++ with range code example

Example 1: random in range c++

v1 = rand() % 100;         // v1 in the range 0 to 99
v2 = rand() % 100 + 1;     // v2 in the range 1 to 100
v3 = rand() % 30 + 1985;   // v3 in the range 1985-2014

Example 2: random number generator c++ between 0 and 1

#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;
int main() 
{
    srand(time(0));  // Initialize random number generator.
     
    cout<<"Random numbers generated between 1 and 10:"<<endl;
    for(int i=0;i<10;i++)
        cout << (rand() % 10) + 1<<" "; 
    return 0; 
}

Example 3: c++ how to generate a random number in a range

min + ( std::rand() % ( max - min + 1 ) )

Example 4: cpp random number in range

int range = max - min + 1;
int num = rand() % range + min;
