Operators

In addition to having operators that perform basic mathematical operations like addition, subtraction, multiplication, and division, C also has operators that perform other functions: like finding the remainder when dividing, or updating the value of a variable. C’s arithmetic operators perform mathematical functions on numbers. The + operator adds two numbers, the - operator subtracts one number from another, the * operator multiplies two numbers, and the / symbol divides one number by another. C also provides assignment operators, which provide a variety of ways to update the value of a variable.
