rand() code example

Example 1: random number generator in php

you can use rand() function for that in php.
Example:
Generate random numbers between 1 to 50
<?php
  echo rand(1,50);
?>

Example 2: c++ random

#include <cstdlib>
#include <iostream>
#include <ctime>
 
int main() 
{
    std::srand(std::time(nullptr)); // use current time as seed for random generator
    int random_variable = std::rand();
    std::cout << "Random value on [0 " << RAND_MAX << "]: " 
              << random_variable << '\n';
}

Example 3: c number randomizer

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

int main(void)
{
	int number, min, max;
	
	system("cls");
	printf("What is the minimum number?\n");
	scanf("%d", &min);
	printf("What is the maximum number?\n");
	scanf("%d", &max);
	
	printf("\nThe numbers:\n");
	srand(time(0));
	number = (rand() % (max - min + 1)) + min;
	printf("%d ", number);
	
	return 0;
}

Example 4: php random number generator

<?php
  echo rand(1,50);
?>

Example 5: 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 6: cpp random int

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
