C++ While loop

In C++, while loop is used to iterate a part of the program several times. If the number of iteration is not fixed, it is recommended to use while loop than for loop.

Flowchart:

Cpp While loop 1

C++ While Loop Example

Let's see a simple example of while loop to print table of 1.

Output:

1
2
3
4
5
6
7
8
9
10

C++ Nested While Loop Example

In C++, we can use while loop inside another while loop, it is known as nested while loop. The nested while loop is executed fully when outer loop is executed once.

Let's see a simple example of nested while loop in C++ programming language.

Output:

1 1
1 2
1 3
2 1
2 2 
2 3
3 1
3 2
3 3

C++ Infinitive While Loop Example:

We can also create infinite while loop by passing true as the test condition.

Output:
