c++ random number between 0 and 10 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: making random numbers in c++

/* rand example: guess the number */
#include <stdio.h>      /* printf, scanf, puts, NULL */
#include <stdlib.h>     /* srand, rand */
#include <time.h>       /* time */

int main ()
{
  int iSecret, iGuess;

  /* initialize random seed: */
  srand (time(NULL));

  /* generate secret number between 1 and 10: */
  iSecret = rand() % 10 + 1;

  do {
    printf ("Guess the number (1 to 10): ");
    scanf ("%d",&iGuess);
    if (iSecret<iGuess) puts ("The secret number is lower");
    else if (iSecret>iGuess) puts ("The secret number is higher");
  } while (iSecret!=iGuess);

  puts ("Congratulations!");
  return 0;
}

Example 3: random number of 0 or 1 c++

#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
}

Example 4: c++ random number 0 to 1

#include <iostream>
#include <string>
#include <random>

int main() {
    std::mt19937 gen (123);
    std::uniform_real_distribution<double> dis(0.0, 1.0);
    double x = dis(gen);
    std::cout << x << std::endl;
}
