How to generate random numbers

Question

How to generate random numbers between 1 to 100 in C
Without using srand()

Answer 1

You can use rand() without first calling srand() [the seed function]. It just produces the same sequence every time you run your program.

---------

If you also wish to avoid using rand(), you can implement a pseudo-random routine of your own. Here is an example, although it is not certified for randomness: https://code.sololearn.com/c5Cgo15HcF98/?ref=app

---------

To reduce its range to 1 to 100, take the random result and use modulo 100 and add 1.
