Different Types of Loops
Loop runs a statement or group of statements multiple times till the given condition is true. There
are different types loops. Although they perform the same task, but their working is different. Let us
take a look at the types of loop.
Different types of loops are:
1. While Loop 2. For Loop 3. Nested Loop
While Loop/Conditional Loop
While Loop executes a statement or group of statements till a given condition is true. Once the
condition is false, the loop is terminated.
Example: To print number from 1 to 10.
Condition: Write numbers from 1 to 10.
Decision: Have we reached number 0.
Pseudocode:
Program Start
set a to 0
while a is less than 10
increase the value of a by 1
display a
Program End
Example: To print a statement five times by using a while loop.
Condition: Till the time the test expression remains true, the body of the while loop will run.
Decision: Have we printed the statement five times or not?
Pseudocode:
Program Start
set a to 0
while a is less than 5
increase the value of a by 1
display Hello World
Program End
Example: To print number from 5 to 1.
Condition: Till the time the test expression remains true, the body of the while loop printing
statement will run and once the condition is false the loop will stop executing.
Decision: Have we printed 1?
Pseudocode:
Program Start
set a to 0
while a is equal to 1
display the value of a
decrease the value of a by 1
Program End
