struct problems

Ok first off I am in CompSci I at college and this is a problem with a program I am doing.

I have a struct with 2 strings, 3 floats, and 3 int arrays. Plus I have a bunch of structs in one array. :roll:
Anyhow I am trying to sort the array of structs into order based on one of the floats. I know the process what I am having problem with is I am getting 2 errors I don't know how to fix. I am unfamiliar with structs so it may be just that.

#1: In my int main() I am trying to call a funtion using my main array and I am getting this error:Error 406: "FinalLab.cc", line 108 # Argument type 'StudentInfo *' does not match expected parameter type 'student *'; '
struct StudentInfo' is not an unambiguously derived class of 'tentative struct student'.
SortByTestAverage(student, studentNumber);
I am using "void SortByTestAverage(struct student[], int& studentNumber);"

#2: In my funtion that swaps the info between two indexes in my array I am getting this: Error 24: "FinalLab.cc", line 121 # '<identifier>' expected instead of 'student'.
nameTemp=student[cs].first;
This confuses the hell out of me and I am using a similar viod to #1

oh I found another the "cs" up there in 2 is a global variable that is getting: Error 249: "FinalLab.cc", line 122 # Subscript operator must have pointer to object and integral operands; 'int[int]' was found.

any help with my homework would be wonderfull hehe. :lol:

Your code looks very strange. Post the entire program (or, even better, a link to it if possible) so that we can actually see what's wrong.

I'm guessing you're supposed to actually specify which structure student[] should be, e.g. "struct StudentInfo student[]"... I could be wrong though. There's not much you're giving to work with...

Compiler errors tend to pile up, so if the error as I interpreted is correct, fixing the first problem in both functions should make the bad text go away :)

That would be a very good idea, yes.

I will see what I can do about posting a copy of the program. I am out of town for the weekend so see you all monday

That is my program in total. Sorry about the angelfireness but being poor means no good webspace for me. :lol:

I think I see the problem. It seems to be because the file is named FinalLab.cc. The .cc extension indicates to a compiler that it should be written in "objective C", which is not the same as C++. When I renamed the file to FinalLab.cpp, it compiled perfectly and I could run it.

Hmm odd it didn't fix a thing for my. Well I am moving the program to a different computer (Mine with mandrake) later to try it cause there is the possibility that it is the compiler on the computer I am using(Schools ancient computer that is very large in size and I am sure has tape wheels).

See my new post in linux workstation -> application to watch my slow progress of getting my linux box working :)

no make that installation forum hehe

Tape wheels... lol! Well, the error messages looked like no compiler that I recognized.
Just remember to rename the file to FinalLab.cpp instead of FinalLab.cc
