include random c++ code example
Example 1: random in range c++
v1 = rand() % 100;
v2 = rand() % 100 + 1;
v3 = rand() % 30 + 1985;
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';
}
Example 3: random number c++
#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;
int main()
{
srand((unsigned)time(0));
int random_integer;
int lowest=1, highest=10;
int range=(highest-lowest)+1;
for(int index=0; index<20; index++){
random_integer = lowest+int(range*rand()/(RAND_MAX + 1.0));
cout << random_integer << endl;
}
}
Example 4: random number 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 5: cpp random int
v1 = rand() % 100;
v2 = rand() % 100 + 1;
v3 = rand() % 30 + 1985;
Example 6: rand() c++
v1 = rand() % 100;
v2 = rand() % 100 + 1;
v3 = rand() % 30 + 1985;
