Here is my program:

#include <iostream>
#include <enmvec>
using namespace std;
using namespace ENM;
double diam, vol, pitch, span, rad, diamExposed;
double NWS(double inches)
{
inches = ( vol * 231.0 ) / ( sqrt( diamExposed ( 2.0 * rad - diamExposed ) ) * span + 0.5 * rad * 0.01745 * rad * 2 * acos( 1 - ( diamExposed / rad ) ) - ( 2 * sqrt( diamExposed * ( 2 * rad - diamExposed ) ) ) * ( rad - diamExposed ) );
return inches;
}
int main(void)
{
double inchesRain = 0.0;
rad = diam / 2.0;
diamExposed = 0.0;
cout << "Enter the volume of the Corley Calibrated Bucket ";
cout << "(CCB) in gallons: ";
cin >> vol;
cout << "\nEnter the diameter of the CCB in inches: ";
cin >> diam;
cout << "\nEnter the rise of the roof, in inches, over a twelve ";
cout << "inch span: ";
cin >> pitch;
cout << "\nEnter the total span of the roof, drip line to drip ";
cout << "line, in feet: ";
cin >> span;
cout << '\n' << '\n';
cout << "Inches of CBB diameter exposed:" << '\t' << '\t';
cout << "Inches of NWS rain: \n";
if ( diamExposed == 0.0 )
{
cout << diamExposed << "\t \t \t The NWS rainfall cannot be calculated. \n";
}
else if ( diamExposed < diam )
{
while ( diamExposed < diam )
{
cout << diamExposed << "\t \t \t \t \t" << NWS(inchesRain);
diamExposed = diamExposed + ( 1.0 / 8.0 );
}
}
else
{
cout << diamExposed << "\t \t \t \t \t" << NWS(inchesRain);
}
}



I am getting error 2314 in line 8

that is the line in the NWS function block that contains the really long function inches = ...............

can anyone tell me where/what I am screwing up?

 

n/m, I found it.

 

I'm glad you found it as my programming experience ended with Fortran and punched tape in Jr. High.

 

and he shows his age.... :P

 

I never used all the spaces to save file size (one space equals 8 bits, that's a LOT of bits...). It does make it easier to see but with the new c++ compilers the spaces only matter in the actual function names.

 

So what was it? I never got as far as learning C or C++. I did a lot of stuff a loooong time ago in BASIC and COBOL (high school and college) and then Pascal (college and then I wrote a program for my employer that took time clock data, compiled it and allowed supervisors to call up the data, correct errors and approve the data and then formatted it to be input into the ADP payroll program).

But I'm just naturally curious.

 

COBOL allowed me to see mamny sunrises in college

 

I used to be able to speak forth, FORTRAN, pascal, basic, COBOL, and COMOL (a weird derivative of COBOL developed for the business community on a C64). Those were the days.... I'm only 28 btw.

 

Can you paste only line 8 here? The ads make up few extra lines( to the right), so I'm not really sure what line 8 is...

 

Ah... "diamExposed" is declared as a variable, but also used (inadvertently) as a function name? I.e. there's a missing '*' operator?

 

'error 2314' is helpful.

may I suggest - you need a new compiler.

 

Yup New England, that was exactly the problem. I spent 3 friggin hours chasin down that thing, I can't tell you how many times I looked right over it.

 

I find those real long computational lines very error prone and hard to debug. When I have something like that to code I tend to do (at least the initial versions) by breaking it up into several lines and using lot of intermediate variables - that way it's easy to see where any computational errors are being introduced, and it also gives the the compiler more lines with less code on each line to point at. Once you get it all coded right and debugged you can condense it to one line if you like, but most compilers will be using lots of registers to store intermediate results anyway, so there's not really any cost to leaving it expanded...

 

I be dipped in doo-doo....

I looked at "C++ for Dummies" long ago, and thought it was a thing I wanted to learn.

Never mind - I'm happy struggling along with advanced HTML and all the rest that allows me to communicate here..

"Any sufficiently advanced technology is indestinguishable from magic"

the logical extension to that is therefore:

"A PRACTITIONER THEREOF IS NO LESS THAN A SORCEROR, MAGICIAN, OR WITCH"

Good luck to you then in your esoteric persuits!!!

After all - someone MUST so do...





Technology and it's several markets are their own necessity

 

Compilers have ignored white-space since the beginning of time.
