rand() c++ code example
Example 1: random in range c++
v1 = rand() % 100;
v2 = rand() % 100 + 1;
v3 = rand() % 30 + 1985;
Example 2: making random numbers in c++
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 3: c++ random
int main()
{
std::srand(std::time(nullptr));
int random_variable = std::rand();
std::cout << "Random value on [0 " << RAND_MAX << "]: "
<< random_variable << '\n';
}
Example 4: cpp rand
std::srand(std::time(nullptr));
v1 = std::rand() % 100;
v2 = std::rand() % 100 + 1;
v3 = std::rand() % 30 + 1985;
Example 5: rand() c++
v1 = rand() % 100;
v2 = rand() % 100 + 1;
v3 = rand() % 30 + 1985;
Example 6: rand() c++
int main()
{
std::srand(std::time(nullptr));
int random_variable = std::rand();
std::cout << "Random value on [0 " << RAND_MAX << "]: "
<< random_variable << '\n';
for (int n=0; n != 20; ++n) {
int x = 7;
while(x > 6)
x = 1 + std::rand()/((RAND_MAX + 1u)/6);
std::cout << x << ' ';
}
}
