What different between rand() and srand() functions in c++?

Answer 1

every time you run the app without srand you will see same number
but with srand it won’t be same
(Note:It’s better use srand(time(0))[you have to import time.h] for getting better resualt

I believe the end result of time(0) and time(NULL) is the same.

The rand() returns a random number.

srand() seeds the random function. Typicaly used to make the function give more random values.
