Find Are underneath curve, using array, structs & functions for 10 terms

[loanrefi]

OS Windows 7, Visual Studio 2012.

I'm building a program to calculate the area underneath a curve using:

Struct
Array

User will be able to enter up to 10 Terms

I need guidance as to what comes next, I think at this point I need a loop but I need guidance. Any advice is greatly appreciated.

My programs doesn't compile right now and I'm getting this error when I try to compile & run:
'"C:\Users\Me\Documents\Visual Studio 2012\Projects\MyProject150713\Debug\MyProject 150713.exe"'
is not recognized as an internal orexternal command,

operable program or batch file.
Press any key to continue...

I'm not going to worry about the error because I think it's because of problems with my code.
