c++ - Same random numbers every time I run the program

Question

My random numbers that output, output in the same sequence every time I run my game. Why is this happening?

I have

#include <cstdlib> 

and am using this to generate the random numbers

randomDiceRollComputer = 1 + rand() % 6;

Answer 1

You need to seed your random number generator:

Try putting this at the beginning of the program:

srand ( time(NULL) );

Note that you will need to #include <ctime>.

The idea here is to seed the RNG with a different number each time you launch the program. By using time as the seed, you get a different number each time you launch the program.
