bookNested For Loops

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.
