int initializes to random large value c++ code example
Example 1: making random numbers in c++
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main ()
{
int iSecret, iGuess;
srand (time(NULL));
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: c++ random
#include <cstdlib>
#include <iostream>
#include <ctime>
int main()
{
std::srand(std::time(nullptr));
int random_variable = std::rand();
std::cout << "Random value on [0 " << RAND_MAX << "]: "
<< random_variable << '\n';
}
