1. Arithmetic Operators: +, -, *, /, % (modulus is also remainder)All the above arithmetic operators are binary operators (the operator is between two operands).It is important to note that in C language, integer division is always integer division, returning only the integer part and discarding the decimal part, as shown in the figure below. … Read more

1. Operators1. Arithmetic OperatorsThe commonly used arithmetic operators are: + – * / %, except for the % operator, the other operators are applicable to both floating-point and integer types. The rule for the / (division) operator is: if either side has a decimal, the result is a decimal; if both sides are integers, the … Read more
Day 5 of C Language: Operators = Letting the Program Perform Calculations 🧮 Learn to calculate from scratch, master addition, subtraction, multiplication, and division in 5 minutes In the first four days, we learned how to make the program “speak”, “remember”, and “ask questions”. Today, we will learn something more practical—how to make the program … Read more
Introduction In the previous section, we learned about the four basic types of operators in C language: arithmetic, assignment, relational, and conditional operators. Fundamentals of C Language (Part Three): Operators and Expressions (Part One) – A Logical Journey from Calculation to Judgment These operators enable programs to perform “calculations and judgments”. But this is only … Read more
The C language provides a rich set of operators for performing various operations.1. Arithmetic Operators Operator Description Example + Addition a + b – Subtraction a – b * Multiplication a * b / Division a / b % Modulus (remainder) a % b ++ Increment a++ or ++a — Decrement a– or –a #include … Read more
⚙️ Detailed Explanation of C Language Operators and Expressions — Comprehensive Understanding of Arithmetic, Logical, and Assignment Operators 🧩 I.
