in c++: with clear explanation please.

Write a program that asks for the users height (inches), weight (inches), and age, and then computes current clothing sizes according to the formulas: Hat size = weight in pounds divided by height in inches and all that multiplied by 2.9. Jacket size (chest in inches) = height times weight divided by 288 Note: Jacket size is adjusted by adding 1/8 of an inch for each 10 years over age 30. (Note that the adjustment only takes place after a full 10 years. So, there is no adjustment for ages 30 through 39, but 1/8 of an inch is added for age 40.) Waist in inches = weight divided by 5.7 Note: This is also adjusted by adding 1/10 of an inch for each 2 years over age 28. (Note that the adjustment only takes place after a full 2 years. So, there is no adjustment for age 29, but 1/10 of an inch is added for age 30.) Now have your program calculate the users jacket and waist sizes after 10 years. Your program should allow the user to repeat this calculation as often as the user wishes. Instructions: Create 5 functions to support the following actions: o Reading input from the keyboard o Calculating Hat Size o Calculating Jacket size o Calculating the waist o An output function which displays or prints to file the clothing sizes for now and 10 years down the road. The main function is the driver where you call your functions in order and have them calculate and run answers.
