Topic overview

C statements normally run sequentially, but conditional statements let a program choose what to execute based on a condition.

In C, common decision-making tools include if statements, if-else statements, if-else ladders, nested if-else, switch statements, and the conditional or ternary operator.

These examples help you practice writing clear conditions and choosing the correct branch for each problem.
