random numbers bewtween 0.1 – 5.0 c++ code example

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

#include <time.h> // So we can use time() function
#include <iostream> // To output results to console

int main() // Main function required in all C++ programs and first function to be called
{
	srand( time(NULL) ); //Randomize seed initialization
	int randNum = rand() % 2; // Generate a random number between 0 and 1

	std::cout << randNum; // Output the results to console
	return 0; //Generate an "EXIT SUCCESS" return code
}
