Need help with C programming

[Lemon[H]ead]

i'm just wanting to compile a C program that was part of my homework using Borland Uber-Crappy-Commandline C Compiler (tm).

I type bcc32 d:\borland\bcc55\temp.cpp to compile the .cpp file and it gives me "8: Declaration Terminated Incorrectly"

the line it refers to is:

float fahr;

(its in a program to convert temperature in fahrenheit to centigrade and i'm declaring the "fahr" variable)

I wouldnt be surprised if its me that has monked up the use of FLOAT.

the whole program is:

#include <iostream.h>
#include <iomanip.h>

{
float fahr=0;
float cent=0;

cout<<"Temperature in Fahrenheit =\n";
cin>>fahr;

cent =(fahr-32)*(5/9);
cout<<"";
cout<<setprecision(2)<<F<<" degrees Fahrenheit is the same as "<<Cent<<" degrees Celcius\n";

return 0;
}

and if i've fadged something up then someone pls say.

W00t never mind.

I messed that program up royally, and just realised now.

forgot int main(), and fadged up references to the fahr variable by calling it F (which it was before).

ok, nm thanks

okay, i do actually need help. When i try to compile i get

'cent' is assigned to a value that is never used in function main()

the program is now:


#include <iostream.h>
#include <iomanip.h>
int main()
{
float fahr;
float cent;


cout<<"Temperature in Fahrenheit =\n";
cin>>fahr;

cent = (32-fahr)*(5/9);
cout<<"Temperature in celcius is:\n"
cout<<setprecision(2) << cent<< endl;

return 0;
}

hmm cent is actually used so i dont know what the hell it means...

help...?

either you goofed when you copied the code to your last post, or you have an error at this line:

cout<<"Temperature in celcius is:\n"

needs a semi-colon at the end. but, if thats where the error is from, that sure is a mis-leading error message!!

cheers!

Borland, for some reason, loves to give those "never-used" messages alot. Normally they are just warnings, and not actually errors though. I think ^hyd^ solved your problem though, i can't find anything else wrong with it.

heh i added the semi colon, the program now compiles...but gives me the answer "-0" for everythin I put in.

I think its the maths thats fscking things up, the way i've written it.

[^hyd^]

might be because of integer division. try this:

cent = (32.0-fahr)*(5.0/9.0);

ciao!

[Lemon[H]ead]

almost worked, all temperatures are the negative of what they should be...


-edit- nm i got it sorted (fahr-32) instead of (fahr-32)

w00t, thanks for the help

[^hyd^]

np!

but... what's the diff: "(fahr-32) instead of (fahr-32)" ... guess it doesn't matter if you say it's working!!

cheers!

[Lemon[H]ead]

lol
i mean (fahr-32) instead of (32-fahr)

i guess i was just so darn excited i could convert from fahrenheit to celcius...
