random number between 1 and 100 c++ code example

Example 1: c++ random number between 1 and 10

cout << (rand() % 10) + 1<<" ";

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: 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;
}
