Problem Passing struct to function

[bigcakes]

Hello, we just learned about structures in my programming class and I am having a hard time editing my existing program using them. Please Help

Input file:
Lewis,Rose 1111 F 75 80 70
Weber,Mark 7821 M 70 69 69
Sooner,Ali 8888 M -1 0 100

What is the problem?

struct structName {
    type1 var1
    type2 var2
    .
    .
    .
    etc.
};

is correct syntax.


P.S. - What environment are you programming on?
(I have a suggestion for your program, but I need to know what you are using to phrase it correctly)

[bigcakes]

Well I am programming in pico which is on my schools system, which is horrible. It was throwing so many errors it was impossible to read them all, haha. I just moved the structure declaration above my prototypes and it stopped throwing errors.

If you want to do any non-school programming you should probably use Dev-C++ or CodeBlocks.
You can find them at:
Dev-C++:
http://www.bloodshed.net/devcpp.html
CodeBlocks:
http://www.codeblocks.org/

P.S. -
Try to stick your prototypes and declarations and stuff in Header (name.h) files. Then add #include "name.h" at the beginning of your Program.
