Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.

My
Program is written in C++

1. Write a program that produces the output shown below:
2. Include four functions:
getNumber
The function prompts the user to enter a float value
The value entered by the user is returned to main()
showMenu
o The function display a menu of choices (A and B)
No value is returned to main()
getChoice
o The function prompts the user to enter a choice (A or B)
o The value entered by the user is returned to main()
showResult
o The function displays the result
If the user entered a or A, the function displays the number and its square.
5.00 squared equals 25.00
If the user entered b or B, the funtion displays the number and its square root.
The square root of 5.00 equals 2.24.
But if the user enters any other character, the function displays:
Invalid choice.
Must be A or B.
Now closing
