Relational and Logical Operators in C (Explained Simply)

Relational and Logical Operators in C (Explained Simply)

Introduction In our previous chapter, we mastered arithmetic operators, allowing our software to act as a powerful calculator. However, real-world software does much more than calculate; it makes decisions. Think about an ATM: If your PIN is correct and your balance is greater than the requested amount, the machine dispenses cash. Otherwise, it declines the transaction. How do we teach a computer to make these logical decisions? We use Relational and Logical Operators . These tools allow the compiler to compare values, evaluate complex conditions, and decide whether a statement is true or false. In this chapter, we will learn the foundation of software decision-making. We will uncover how C handles truth, explore the "equals" trap that catches every beginner, and combine conditions to build smart logic. How C Handles Truth (0 and 1) Before we look at the operators, you must understand a fundamental quirk of the C language. Many modern languages have a built-in "Boolean" …
