Srand (seed random ) is used to seed random numbers and is used before calling the rand() or the random number generator.
Seeding random numbers ensures that each time the code is executed the number generated is completely random.
srand requires one parameter. For most cases it is sufficient to make this parameter time(NULL) [remember to include time.h] as this will seed a new bunch of random number every second
You can use rand(). Make sure that you use srand()to generate the seed for rand() (if you do not, you get so called pseudo random numbers).
The header file for random functions ( like rand(), srand() ) is stdlib.h in C and cstdlib in C++.
I don't believe 'srand ' is an English word , -gibberish.
b+b+b+c+c+c+c =3b+4c
c + c + 2c + c + c = 6c
b + b + b + c + c + c + c = 3b + 4c
4c
c + c + c + c + c = 5 * c.
It is an abbreviation for Local Area Network.
There are no "primary and secondary keys" in c and c plus plus.
3c
There is no such thing as 'unix C++'.
