The first problem I notice: you cast malloc(), which suppresses the error you should receive for not including stdlib.h ...

Even after fixing that, it still segfaults, so I'm looking at the rest...

This declares a string literal. Nothing wrong with that as long as you don't try to modify the string (you'll likely segfault if you do). If you don't want a string literal, you can assign the...

Also you want to pass "width" to printsquare()

edit:

You pass it to getwidth() but that isn't useful at all. If you declare "width" in getwidth() and return it, that's good enough; then you...

You said you didn't want the exact answer, so I didn't write your program for you.

You can simply check the input inside the getchar() loop with isdigit() or whatever you like.

You can approximate fgets() with something like the following:



#include <stdio.h>
#include <stdlib.h>

int
main (void)
{

You want something like this:



int ch;
...
while ((ch = fgetc (textfile)) != EOF) {/* do your thing */}


You need to find a good reference so you can look up the standard functions...

C99 supports this; there may be good reason at times for not relying on its implementation on a given compiler, but it's C.

It's also unfortunate that "validate" is tested when it's uninitialized.

I'm primarily a unix guy, but I believe conio.h is a borland extension ... so it's not valid in more than just unix: it's not standard C at all

You can use getchar() instead, which is in the FAQ

The standard type for that is "ptrdiff_t" as defined in stddef.h

If you include "fstat" and/or "lstat" in your google string, you should get one of the many webified man pages.

If you're using linux, google on LFS (large file support). You just need to compile with an extra flag or two with gcc in order to change off_t from 32- to 64-bit.

It's hard to know what's going on without seeing the source.

Dot files are conventionally treated differently by unix utilities and apps, but as far as standard C functions are concerned, they're just files with filenames that start with a dot. They're not...

Like quzah says, you need to put a printf() loop inside the sort function, for example:



#include <stdio.h>


void sort (int a[], int n);

int main (void)

Hey, you forgot common lisp!

I have to admit that my first reaction to a warning that suggests that I need a cast is to look to see what I did wrong. It's generally fixable without the cast, though this probably depends...

According to the standard, redefinition is allowed, though with constraints (6.10.3 item 2). gcc emits a warning with the following code, but it compiles.

According to the standard, it's 0 or 1.

I see your point, though ... it shouldn't really matter.

strchr() returns a pointer to the first occurrence of a char in a string, or NULL if the char isn't found. It's a very useful function for parsing text, and it's in the standard C library. You...

int i = 0;

This kind of declaration is allowed in C99 but not in previous versions of ansi C (or K&R C). This isn't really an issue unless you try to use a...
