Which branch structure does a program use to output "Yes" if a variable's value is positive, or "No" otherwise?

Selection control structure

Explanation:

This is often referred to as if-conditional statement;

This condition tests for a condition and performs a sequence of operation depending on the result of the condition;

Take for instance, the following program written in python

x = int(input("enter any number: "))

if x < 0:

  print("Yes")

else

  print("No")

The above checks if the input number is less than 0,

If the condition is true, it prints Yes

If otherwise, it prints No

well you could find somebody who doesn't want theirs and ask for it or possibly trick a dealer into giving it to you for free.
