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;

The RAND function in stand-alone applications generates the same numbers each time you run your application because the uniform random number generator that RAND uses is initialized to same state when the application is loaded.
random seed() example to generate the same random number every time. If you want to generate the same number every time, you need to pass the same seed value before calling any other random module function. Let's see how to set seed in Python pseudo-random number generator.
If you use randomNumber() multiple times in your program it will generate new random numbers every time. You can think of each randomNumber() like a new roll of a die.
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.

You need to give the randum number generator a seed. This can be done by taking the current time, as this is hopefully some kind of random.
#include <cstdlib> #include <ctime> using namespace std; int main() { int r; srand(time(0)); r = rand(); return 0; } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
