Program Errors

cmangum3 (14)
Hey all, so I have this code right here but it's returning a fair amount of errors and I was wondering if I could have a couple more eyes to help me correct them.

Thanks in advance. I'm working on them now so I'm sure I'll have quite a few gone one my own by the time I get responses.

Always start with the first error, and look at the line number; the actual error will usually be close to the line number that it says something wrong is happening on (usually!).

Your first problem is that you're declaring std::string result in more than one place - see line 74 and 117. Only declare it once.
Same thing with digit and checksum.
You also can't declare the variables there because they are within the same switch block.

102	[Error] 'stoi' is not a member of 'std'
103	[Error] 'to_string' is not a member of 'std'


Are you compiling with C++11? Add -std=c++11 or if that doesn't work, -std=c++0x to your compiler options if you're working with GCC (g++). Some older version of MinGW have a bug where those string conversion functions don't work, so you have to make your own.

You also never define a function called CreateBarCode.

#include <iomanip> is needed for std::setw

cont, zipode --> both typos.

A "do" loop is actually a do-while loop. The require syntax looks like this:
1
2
3
4
5
 
bool my_condition = true
do
{
    std::cout << "Do stuff, modify condition to false to end the loop" << std::endl;
} while (condition);


PRO-TIP: COMPILE INCREMENTALLY. Don't write your own program in one go and then try to compile. Make sure it can compile, and then add more onto it. Otherwise, you end up with 100 errors like this.
