program w/ switch AND nested if. six error messages

Expand Post »
Hello,
this is my first post, so i'm sure i'll fumble it a little bit.

I'm writing a program that has a switch, a nested if, and an output choice of console or new file on a:.
I feel like all my switch and nest is good, but i'm missing something, like a preprocessor. at least i hope I'm that close

here's a list of errors:

LINE 49 call to undefined function 'SWITCH' in function main()
LINE 49statement missing ; in function main()
LINE 96possible use of tot_chrg' before definition in function main()
LINE 101undefined symbol 'choice in function main()
LINES 113 115 117 119 statement missing ; in function main // this appears four times
LINE 127[three of my different variable names: water_chrg school_fee elec_chrg] are used but never defined in function main()
LINE 127[two of my variable names: bal_due SAN_CHARGE] is assigned a value that is never used in function main()


thanks
jamie

Re: program w/ switch AND nested if. six error messages

Start by remembering that C++ is case sensitive. Then make sure that every variable you use is defined before it's used.

Re: program w/ switch AND nested if. six error messages

I guess i'm not exactly sure what 'defined' means; doesn't the result of my switch and nested if statements define them?

>I guess i'm not exactly sure what 'defined' means
Your variable tells the compiler, "Here I am! I exist. Set aside storage for me." And you do it like so:
C++ Syntax (Toggle Plain Text)
  1. int main()
  2. {
  3.   int variable; // variable is now defined
  4.  
  5.   // ...
  6. }
>doesn't the result of my switch and nested if statements define them?
Not in C++.

Re: program w/ switch AND nested if. six error messages

I guess I'm in over my head; are we talking about this section?

const double SAN_CHARGE = 12.50,
TAX_RATE = 0.07;

char account [6], // No dashes
date [20]; // Month Day, Year

ofstream outfile;

int children;

long int electric,
water;

double bal_due,
elec_chrg,
school_fee,
tax,
tot_chrg,
water_chrg;

One problem at a time. Change your keywords (switch, if, else, and so on) to lower case first, then you should compile with only warnings and we'll work from there.

Re: program w/ switch AND nested if. six error messages

it still won't compile.. i think i'm up the proverbial creek!

should it be:

int main ()

Re: program w/ switch AND nested if. six error messages

Okay, now include <iostream.h> and declare your variables. Notice that what we're doing here is incremental fixes. There are so many problems that you can only work with one at a time, so you walk down the list of errors from the top, recompiling as you fix them because sometimes one fix will remove several error messages.
