using randin c++ code example

Example 1: random number 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 2: how to make rng in c++

#include <stdio.h>
#include <stdlib.h>
#include <ctime>

int main() {
  srand((unsigned) time(0));
    printf("Your dice has been rolled! You got: \n ");
    int result = 1 + (rand() % 6);
    printf("%d \n", result);
   switch (result) {
    case 1:
        printf("Your prize is our original T-shirt!");
        break;
    case 2:
        printf("Your prize is our original cap!");
        break;
    case 3:
        printf("Your prize is our original necklace!");
        break;
    case 4:
        printf("Your prize is our original keychain!");
        break;
    case 5:
        printf("Your prize is our original cup set!");
        break;
    case 6:
        printf("Your prize is a set of original keychains!");
        break;
    default:
        printf("Error");
        break;
    }
