Nested Loops
Explore how to use nested loops in C++ to perform repetitive tasks in multi-dimensional scenarios. Understand the structure and scope of variables within nested for and while loops, and learn how to control loop execution using break and continue. This lesson includes practical examples and exercises to build your confidence in implementing nested loops for tasks like matrix iteration and pattern generation.
Nested loops are loops inside other loops. They are often used when we need to perform repetitive tasks in a multi-dimensional way, such as iterating over the elements of a matrix (e.g., iterate over all the columns of a row before moving on to the next row and repeating the process) or generating combinations of items.
Nested for and while loops
It is possible to nest for and while loops. Nesting means including one for or while loop in another for or while loop. The inner for / while loop will execute all its iterations for every single iteration of the outer for / while loop. The syntax for a nested for ...
