Concept
Arithmetic and Comparison Operators
Plus, minus, star, slash, and percent perform math. Comparison operators compare two values and produce a bool.
By the end of this lesson
- Explain the core idea behind Arithmetic and Comparison Operators.
- Predict output before running a change.
- Test one realistic and one unusual input.
- Use the result to make the next decision.
How to study this page
- 1. Read one concept.
- 2. Change the example.
- 3. Run, compare, and explain.
- 4. Complete the challenge below.
ExampleRunnable
int a = 10, b = 3;
std::cout << a % b << std::endl;
std::cout << (a > b) << std::endl;Self-check before continuing
Without looking at the example, describe what changes when you modify one input in Arithmetic and Comparison Operators. Then reopen the editor and prove your explanation with a small test.
You are ready to continue when you can predict, test, and explain the result.
Your turn
Print the remainder of dividing 17 by 5 using the percent operator.
