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]

Logical AND = &&, logical OR = ||, logical NOT = ! .

Logical operators are used to combine or negate relational (true/false) expressions:

Logical AND ( && ) - the result is true only when both operands (conditions) are true.
Logical OR ( || ) - the result is true when at least one of the operands is true. …
