Algorithm of Nested Do while Loop with 4 Levels

The algorithm is a step by step procedure to solve a procedure. Let’s see the algorithm to solve the mentioned problem.

1. Start
2. Declare Variables
3. start outer loop
4. start inner loops
5. print output ” **”
6. increment the variable in every loop.
7. Stop

Pseudo Code of Nested Do while Loop with 4 Levels

1. tag <script>
2. Declare & initialize var i
3. Declare & initialize var j
4. Declare & initialize var k
