How to Work with Nested For Loops in C++

A nested for loops are almost the same as a nested while loops. They allow you to create a set of iterations within another set of iterations, but in more convenient way. It is particularly useful when dealing with two-dimensional or multi-dimensional data structures with elements your want to iterate through.

Remember like in the previous section, we had a task that involved creating a rectangle in a console using three loops? As you already could guess there is a more straightforward and flexible way to accomplish this.

cpp

main

copy
123456789101112
#include <iostream> int main() { for (int i = 0; i < 5; i++) { for (int j = 0; j < 5; j++) { std::cout << '#'; } std::cout << std::endl; } }

Understanding nested loops may be challenging initially, but once you grasp the concept, it becomes easy. So, let's try to practice.
