Well I'm getting some errors when I'm trying to compile this C++ program. It's really starting to make me mad as the code should be correct. Here is a list of the problems I am getting thanks for the help.

prog12.cpp: In function `int main()':
prog12.cpp:72: error: invalid conversion from `const char*' to `char'
prog12.cpp:89: error: expected primary-expression before "else"
prog12.cpp:89: error: expected `;' before "else"
prog12.cpp:92: error: expected primary-expression before "else"
prog12.cpp:92: error: expected `;' before "else"
prog12.cpp:100: error: ISO C++ forbids comparison between pointer and integer
prog12.cpp:126: error: invalid conversion from `const char*' to `char'
prog12.cpp:160: error: expected `}' at end of input

[bla!!]

post your code. You have some very simple formatting errors. I'm guessing you missed a semicolon somewhere and it's throwing off the rest of your code.

You've got quite a few formatting errors in there.

Go back through, thinking of what conditinals you actually want, and then analyze your parenthesis.

Block everything in your IF statements with brackets {}. Even if they're only one liners. I think you're missing quite a few closing brackets and some of your conditional logic is off.

[toxicity_27]

Can anyone else help me? I just want to get this thing done so I can get it off of my mind.

First off, replace all instances of:

if (code = "G")

with:

if (code == 'G')

On line 71, you make a reference to 'water1' which has not been previously declared (it doesn't exist yet).

And the end of the code block for the if statement starting at line 79 is missing it's closing brace.

Okay, so I fixed those errors, but now I get these errors*.

Hmm, it seems you lack much attention to detail.

I said replace all instances of:

if (code = "G")

with:

if (code == 'G')

Note the use of single quotes, not double.

Wow, I'm sorry, I didn't even notice that, yes I must lack attention to detail .
