How does the random number generator work in C?

Question

I\'m trying to generate random number between 0 and 40(inclusive). So the code I Implemented is this-

 y=rand()%41;

Answer 1

It is generated by an argument passed seed. To generate different numbers add this before calling the rand() function:

srand (time(NULL));

This generates a new random seed.

You should have this library: #include And if you still have an error use this one as well: #include
