Write a program that asks the user to enter the number of spheres. Then, your program should ask the user to enter the radius (r) for each sphere to calculate its volume and then display it with two digits after the decimal point. At the end of the input process, your program should display the message "Done...". Use the following formula: 3 Volume =ar 4 Note: you must use a loop and mathematical functions to solve this problem correctly. The following are sample runs.

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.
