C++ - If / Else

Overview

Estimated time: 25–35 minutes

Control flow with if/else. Learn chained conditions and the ternary operator.

Learning Objectives

• Write conditional logic using if/else if/else.
• Use the ternary operator for simple expressions.

Prerequisites

• C++ - Math

Examples

int x=5;
if (x > 10) { /*...*/ }
else if (x > 0) { /*...*/ }
else { /*...*/ }

int y = (x > 0 ? 1 : -1);

Common Pitfalls

• Using assignment (=) instead of comparison (==).

Exercises

1. Write a function that classifies an integer as negative, zero, or positive.
