My question is do you have to be good at math to be a good programer?

I don't think so (although it could help in some scenarios). I think it would be most important if you're writing software that deals with number crunching with mathematical formulas, etc.. Otherwise, I think most of the math you'd need is fairly simple stuff. For instance, you often have to think about things like array indexes to get information from an array or sometimes splice information into an array. One common scenario for that is string parsing (for instance, parsing command-line options).

I think much of programming is being able to learn the various programming languages and programming libraries and having creative insight to figure out how to use them to do what you want in terms of software. And what you want to do with software could be any number of things, sometimes requiring heavy math but sometimes not.

Maybe you can help walk me through my errors with Open Watcom:

Here's my first error:
legion\scores.cpp(99): Error! E029: col(25) symbol 'getline' has not been declared

for (i = 0; !ins.eof ( ) && i < 10; i++)
{
getline (ins, top_five[i].name, '#');
ins >> top_five[i].score;
eatwhite(ins);
ins >> top_five[i].tnclass;
eatwhite(ins);
}

I don't understand this one.

Here's my first error:
legion\scores.cpp(99): Error! E029: col(25) symbol 'getline' has not

been

declared

for (i = 0; !ins.eof ( ) && i < 10; i++)
{
getline (ins, top_five[i].name, '#');
ins >> top_five[i].score;
eatwhite(ins);
ins >> top_five[i].tnclass;
eatwhite(ins);
}

I don't understand this one.

It doesn't know about 'getline'. You can do either of the following:
- Prefix that call with std:: - Example:
std::getline(ins, top_five[i].name, '#');
- After your #include lines, put "using std::getline;" (without the double- quotes)

Also, be sure to #include <string>

This is for the first idea:

leg034.cpp(42): Error! E921: col(18) namespace 'std' not allowed in using-declaration
leg034.cpp(42): Error! E006: col(11) syntax error; probable cause: missing ';'

still with this error:

scores.cpp(99): Error! E029: col(25) symbol 'getline' has not been declared

I added the second one and I get this error.

leg034.cpp(42): Error! E926: col(12) syntax error: 'std::getline' has not been declared as a member

Also, be sure to #include <string>

#include <string> is there up top.

Can you post the code that is generating those errors? It's difficult to help without seeing the code (what's at columns 18 and 11?). This is what it should look like (underneath your #includes and before your functions):
using namespace std;

It looks like the compiler knows about namespaces, so I'm not sure why std would not be allowed (unless perhaps it's an older compiler and its headers don't declare the standard library things in the std namespace).

Here's the function:

-- snip --

bool open_input_file (int& i)
{
ifstream ins;

ins.open(SFILE);
if (ins.fail( ))
{
// cerr << "Creating New Top 10 Scores..." << endl;
ins.close();

return false;
}

for (i = 0; !ins.eof ( ) && i < 10; i++)
{
std::getline (ins, top_five[i].name, '#');
ins >> top_five[i].score;
eatwhite(ins);
ins >> top_five[i].tnclass;
eatwhite(ins);
} // end while

ins.close ();

return true;

} // end open_input_file

-- snip --

It looks like the compiler knows about namespaces, so I'm not sure why std would not be allowed (unless perhaps it's an older compiler and its headers don't declare the standard library things in the std namespace).

I'm using Watcom 1.9 at the moment. I've also tried DJGPP. I'm not sure what to do at this point. I was up all night hassling with this.

I would say you need basic maths. Like the four operators, + - / *.
(Add, subtract, divide and multiply) but that's really all. The more
math you do the better, it gets your brain working in different and
wonderful ways which is never bad and can help in programming.

Another nice thing in programming is abstraction. Gotta love it.
