C Program Help

[saggie]

I cannot write this C program that uses a function to calculate the area of a circle, witha circle's circumference. This function (findArea) should call a second function (findRadius) which will return the radius of the circle. I need to show that the program can display the circles area on the screen.

The functions should only calculate the required information, they should not display. All display (printing to the screen) should be done in the main function. The user should be prompted to enter the circle’s circumference – this too should be done in the main program.

The program should repeat until the user wants to stop.

Use the following formulas in your program:
r = c / 2π
a = π r2
r = radius
c = circumference
a = area
π = 3.1416

I at least need help getting the started, can anyone help me?

What have you done so far? Can you start by writing the findArea function, assuming that your findRadius function will work properly?

I am having troubles just getting started. My manual is very basic. I t is the "In Easy Steps" book (not very easy), it tries to teach C in 75 pages.

Well, unfortunately, we can't do your problem for you. At least try something, post the code you wrote, and we can help you debug it/figure out what's not working, but we can't do it all for you.

I will get something working and I will post what i can get done.
