My friend doesn't believe you. ;)

Are you storing the patient data in a text file or a database? If you use a database, your question is easily answered.

If you are using a text file to store the data, you might want to consider...

I was under the impression that some functions can be implemented as macros instead. I thought that's why they list it as a 'Feature Test Macro'.

But after reading 'man 7 feature_test_macro' I...

If you are running this on Linux, you cannot use getch() from <conio.h>. If you still want that functionality, you need to use the following:

They're useless, because if it didn't appear, the understanding would be the same. It's also useless, because you typed two words (although one is suffering from poor spelling), when I show you how...

Don't do this. Either put nothing, or change the two useless words to two meaningful words.


// Print arrays.

I don't think I'm proficient in C, as I have never taken any courses on C. I read C Primer Plus about 18 years ago, and dabbled in it occasionally.

About 5 years ago, I felt I wasn't really...

I don't know why this idea escaped me.

What have you tried?

Instead of a hand out, what code do you have so far?

I was thinking he also wants to have the results sorted, which stops you from using the above method, doesn't it? Because if you sort the frequency of your example, the relation to letters would be...

I would make a struct then.


struct _alphabet
{
int frequency;
char letter;
};

Then you can just bubble sort based on the frequency without the relation losing meaning.

In your first post you ask how you can sort them. In your last post you ask how you can count the frequency of the letters.

Does the int array contain integers that represent human readable...

What types are the arrays?

There's most likely another way.

Ty for your replies.

I changed the call to add_file like so:

And all references to 'array' in the function add_file I changed...

Thank you, your dick-head comment helped me a lot.

I have my C program complete. But I need to create a GUI for end (L)users.

Can someone recommend a simple language for creating a front end to my C project?

Thank you very much for your input. I'm just starting to program in the C language, and wanted to do this project. I was afraid I was setting out to try and do something that couldn't be done...

I see this as being a problem. What about if I add a unique entry in place of the desired serial number, make the image file and search the .img file by bit shifting until a matching pattern is...
