Question

Here is the code that doesn’t work:

Enemy.strength = srand((unsigned)time(NULL)) % 10;

Enemy.strength is an int

I did some research and i found you can’t directly define a variable with rand/srand
such as:

a = rand();

I am just wondering why and if there is a way around this or what alternative you suggest

Language: C… not C++

Answer 1

srand(seed) returns void. It is for seeding the random number generator. rand() returns a pseudo-random integer between 0 and RAND_MAX (defined in stdlib.h).

So to get a random strength for your enemy you should do something like:

Enemy.strength = rand() % 10; // gives a strength between 0 and 9

You can place a call to srand somewhere in your code, but it only needs to be called once. It should be called before any calls to rand().
