NESTED LOOP
Learning Objectives
10.1 Nested for Loop 10.2 Nested while Loop
10.3 Nested do-while Loop 10.4 Using break Statement in Nested Loop
10.5 Using continue Statement in Nested Loop
In the previous chapter, we have learnt about loops and their Definition
uses. Loops are quite helpful in creating complex programs.
They helps us to reduce the lines of code, which helps us to A Nested loop is a loop inside another loop,
create lighter codes that use memory efficiently. We can also where the inner loop executes completely for
use a loop within another loop creating a nested loop. There each iteration of the outer loop.
are different types of nested loops.
Types of Nested Loop
Nested for loop Nested while loop Nested do-while loop
Structure of a nested loop:
Outer loop structure statement
{
Inner loop structure statement
{
Statements inside inner loop
}
Statements inside outer loop
}
Let us study the different types of nested loops in detail.
