How to use random function in c++

Answer 1

If you write

int main() {

cout << rand();

}

then it will put out a random number.

Answer 2

After include time.h library...

int main(){
srand( time( NULL ) ); // True random numbers

cout << "Example: \n"
<< rand() // Random << endl
<< rand() % 50 + 3; // Random ( 3 - 50 )
}
