iostream help...

Using g++ 2.95.4. When trying to compile this function:
void main()
{
float mean, numAbove = 0;
ifstream nmbrs;
nmbrs.open("nmbrs.txt", ios::in);
.......
nmbrs.clear();
nmbrs.seekg( 0, ios::beg );
mean = mean / 100.0;
numAbove = numAboveAverage(nmbrs, mean);
.........
}


float numAboveAverage(istream & nmbrs, float mean)
{
float AboveNum;
}


I get the following error:
project3-1.cpp:62: implicit declaration of function `int numAboveAverage(...)'
project3-1.cpp:62: warning: cannot pass objects of type `ifstream' through `...'

Im lost, anyone have any input? Thanks in advance.

I can't really see, where is the mistake here.
I have overflow the text and noticed, that you haven't posted the complete code.

question:

Have you done a declaration for your datatypes???????


-> And the is something about declarations in the error message!!!!

I just added the datatypes to the top of the screen... should I post all the code? 77 lines total as of now!.

Actually the entire program works, until that function is called. I I comment out the call to the numAboveAverage() it works w/o error.

OK, so whats your point... was looking for help not pretty little sarcastic cartoons.

it's ironic because I gave a lecture to my classmates today about why void main() is bad practice; I'm just saying that I feel like hurling myself off of a building upon seeing void main() after that 3-hour class :p

Sorry

>project3-1.cpp:62: implicit declaration of function `int numAboveAverage(...)'
I'm not familiar with G++ error messages, but this appears as if you forgot to prototype numAboveAverage, the compiler assumed a function returning int and taking any number of arguments, and didn't like when you passed it an ifstream object.

I thought it was cute. ^_^ And BMJ's advice was sound, even if it wasn't the help you were looking for.

that cartoon is sweet, lmao



ahahahahahahaha


ahahahahahahaahahash



sweet :D

Salem's avatar better shows the void main hatred:

ahh.. prototype... schmack, my mistake. I did like the cartoon, however I didnt know whether or not he was telling me to take a jump off a building or what .. this being my first post I was like what the?.. :0), anyways thanks.

Oh! No no no! I would never tell a first time poster to jump off a building! I love new people on the board!

Just imagine speaking and arguing for 3 hours about void main() vs. int main()

Upon seeing void main() I wanted to throw myself off a building into oncoming traffic :D

You have to be more forceful, it takes me at most 30 seconds to beat reality into someone about void main, and even then most of the time is spent walking to my library, pulling out the ISO Standard, and flipping to the (bookmarked!) page. Every once and a while I hit them with the book, but only for 2nd+ offenses.
