Loop Statements

Suppose in the calculation of area of the circle, we need to take 10 inputs for radius and calculate the area for each input, it is a very tiresome process to write 10 scanf/cin statements for each input and calculate the radius for each one. It is for this reason the loop statements are very useful in any programming language.

C and C++ provides the following loop statements:

• while-loop
• for-loop
• do-while-loop
