C++ For Loop

This lesson is part of C++ · All levels

Summary

This lesson discusses the most commonly used iterations of for when the number of iterations is already known at the beginning. Structure for combines the initialization of control variables, conditions, and incremental in a single line so that the code becomes concise. You also learn the pattern of a clustered loop to process two-dimensional data like a matrix.

Key points

Structure for: for (initialisation; conditions; increments).
The control variables are generally declared directly within the for.
Loop for ideal for iterations with a fixed number.
A loop in a cage means there is a loop inside another loop block.
