how to write a code of matching a random number from a user input number using if-else statements.

Question

simple basic code is needed.

Answer 1

You mean something like a "Guess the number" game?
If so, then try to find examples in Code Playground, many had written such codes 👍

Answer 2

Basic Pseudo code would be like

Random = some random number
Input = user_input

If Random == Input :
Guess is correct
else:
Guess is wrong

You can make a code based on this pseudo code and change it
however you like... You can also search other similar codes for reference.
