Reread your text on basic syntax.[code]int words { int words = 1;[/code]It looks like VB. Functions should have a parenthesized parameter list, and it's not a good idea to name a local variable the same as the function.

AD: There's no need to cast away constness (it may do no harm, but I avoid things that can be bad habits). And your integer comparison function can be a victim of integer overflow.

You've got a lot there that needs tweaking. I first found it confusing how you got typos in what would appear to be a copy-and-paste, but I guess what you posted was an intermediate attempt since it wouldn't even compile. After fixing those and ditching the user input for the …

Why are you using this form: [INLINECODE](a + i*arraysize +j)[/INLINECODE] rather than subscript notation [INLINECODE]a[i][j][/INLINECODE]? It's simpler, for one, and it is also easier to see that [INLINECODE](a + i*arraysize +j)[/INLINECODE] means the same as [INLINECODE][COLOR="Magenta"]&[/COLOR]a[i][j][/INLINECODE]. Or that [INLINECODE][COLOR="Magenta"]*[/COLOR](a + i*arraysize +j)[/INLINECODE] means the same as [INLINECODE]a[i][j][/INLINECODE]. So what you …

You're using sscanf as if it were fscanf. You can make the two behave similarly, but sscanf will need different directives and variables.
