What does the '%' operator represent in programming languages?
Answer Details
In programming languages, the '%' operator commonly represents the modulus operation. This operation finds the remainder after dividing one number by another. For example, in the expression 7 % 3, the result would be 1, because when 7 is divided by 3, it goes twice (which sums to 6) with a remainder of 1.
The modulus operator is often used in scenarios where you need to determine if a number is divisible by another, or when you are trying to loop back to the beginning of a list or array after reaching the end. It is important to distinguish it from other operations like assignment, concatenation, and exponentiation, each of which serves entirely different functions in programming.
