Concept understanding — Relational and Logical Operators in C

Relational and logical operators are used to test conditions, and their result is always either true (1) or false (0). Together they let a program make decisions.

Relational operators compare two operands:

< less than, > greater than, <= less than or equal, >= greater than or equal, == equal to, and != not equal to.

A crucial distinction is between = and ==: the single = is the assignment operator (it stores a value in a variable), while the double == is the relational equality operator (it tests whether two values are equal). Confusing the two is a classic beginner mistake.

Logical operators combine or invert conditions:

&& logical AND - true only if both conditions are true.
|| logical OR - true if at least one condition is true.
! logical NOT - reverses a condition (true becomes false). …

[!TLDR]

= assigns a value; == compares two values.

The single equals sign = is the assignment operator: a = 5 puts the value 5 into the variable a. The double equals sign == is a relational operator that tests equality: a == 5 checks whether a equals 5 and yields 1 (true) or 0 (false). Confusing the two is a common source …
