Random number generator, C++

Question

I know there is a bit of limitations for a random number generation in C++ (can be non-uniform). How can I generate a number from 1 to 14620?

Thank you.

Answer 1

the modulus operator is the most important, you can apply a limit with this modulus, check this out:

// random numbers generation in C++ using builtin functions
#include 

using namespace std;

#include 

using std::setw;

#include    // contains function prototype for rand

int main()
{
// loop 20 times
for ( int counter = 1; counter <= 20; counter++ ) {

    // pick random number from 1 to 6 and output it
    cout << setw( 10 ) << ( 1 + rand() % 6 );

    // if counter divisible by 5, begin new line of output
    if ( counter % 5 == 0 )
        cout << endl;

}

return 0;  // indicates successful termination

} // end main
