C ++ PROGRAMMING

The purpose of this program is to determine the amount of cloth in square inches needed to make a certain kind of garment. Rather than using one big pile of main( ), you need to use functions for these calculation that incorporate pass-by-value parameters. In addition, you need to include various int or double const declarations within your program. Finally, embed your program in a loop so that the calculation can be repeated as often as the user wishes. IN ORDER TO RECEIVE FULL CREDIT, YOU MUST DEFINE AND CALL FUNCTIONS AND PASS ARGUMENTS.

You should base your calculations on the following table:

Shorts

The following program dialogue should help you figure out what kind of program I am looking for.

Tailor Fabric Calculator:
Whaddya want? [P]ants or [S]hirts or shor[T]s: P
Gimme your waist size in inches: 30
Gimme your height size in inches: 72
Pleaded front? [Y/N]: Y
Baggy Look? [Y/N]: N
For your pants, you'll need 79.9968 square inches of fabric!
Try again? [Y/N]: Y

1 1/2 square inch per waist size inch of the person being fitted 2/3 square inch per waist size inch of the person being fitted 1 3/10 square inch per waist size inch of the person being fitted 4/9 square inch per height inch of the person being fitted 3 3/8 square inch per height inch of the person being fitted 1/2 square inch per height inch of the person being fitted 1/10 square inch per waist size inch of the person being fitted, if pleaded front is desired 1 1/2 square inch per arms length inch of the person being fitted, if long sleeves are desired If pockets are desired, add an extra 5% to the fabric amount calculated so far If baggy look is desired, add an extra 15% to the fabric amount calculated so far
