This page (http://www.instant-registry-fixes.org/troubleshooting-and-preventing-ntdlldll-errors/) says that ntdll.dll is "a Native API file of Microsoft operating systems and it contains NT kernel...

char filenames[fcount][16];
You're declaring a variable-length array here. It's not standard C89 to do that. If I were you I'd just declare the array as
char filenames[MAX_FCOUNT][16];

You can't assign anything inside a structure declaration. A structure declaration just defines a type. It's like a blueprint; you're telling the compiler, "if I ask you to create a Something, this is...

Well, it has one advantage over a return value -- you have to pass in an address, whereas you could ignore a return value. :) I don't think that's how I would write it, though.

Why is root a global variable? As far as I can see, it doesn't need to be, and it's just causing confusion because several functions take a root parameter.

Declaring variables inside for loop initialization sections is indeed C99-only. I wouldn't do it if I were you.


double just has more precision (usually). Oftentimes, a float is 4 bytes and a...

You can even use fancy preprocessor macros and so on to replace the malloc()/free() calls in existing code with your own functions.

BTW, __LINE__, __FILE__, __DATE__, and __TIME__ are all standard...

Why don't you use the quadratic formula (http://en.wikipedia.org/wiki/Quadratic_equation#Quadratic_formula)? If all of the equations are quadratic, it should work.

You can do square roots in C...

/* replaced 0 by 1 */
Depending on who you ask, the first fibonacci number can be 0 or 1. (Personally, I'd agree with you and have it 1.)

Why not use more descriptive names than num1, num2, etc?

if(fib = fnum)

Try ==. = is for assignment, == is for comparison. (Your compiler should warn you about this if you enable warnings.)

Plus I don't think this is what you want.
for (fib=1;...

You don't want a semicolon after a while loop:
while( number<= 0 ); {
->
while( number<= 0 ) {

My only suggestion is to try a profiler so that you can see exactly where your program is spending all of its time. If you have access to the code from the other program, profiling it as well might...

What are you forgetting here?
for(j=0;j<41;j++)
for(i=0;i<79;)
txt[j][i]=32;
Hint: it's an infinite loop . . . .

And it's a lot easier to use character constants like ' ' and '\r' in your...

You could save the numbers as you find them instead of printing them, say in a char array, and then print that array in reverse. On the other hand, it would probably be better to use a different...

@Adak: I already mentioned that, though admittedly it was buried in my long post.

The main logical problem with your code still exists. Numbers aren't the same thing as strings. You can't have an...

for loops generally have three sections. You've forgotten the increment section. :)

You're also missing a closing parentheses on the strlen() call . . . .

But we know what you mean. :)
char...

Yeah, most of the time it's a good idea. Sorry I didn't explain it further.


Yes. Accessing such memory could lead to data corruption or at the very least segmentation faults.


Correct.

...

while( line % 55 != 0 )
Note that 0 % 55 is 0, so you'll pause before printing anything, and then display 55 lines ad infinitum. The best solution is probably to use something like this:
while(...

That last post was getting crowded so I thought I'd start another one -- especially since it's a higher-level one.

Since you're trying to handle both numbers and strings, why not have two separate...

GCC doesn't like your code.
sort.c: In function ‘read_list’:
sort.c:13: warning: format ‘%s’ expects type ‘char *’, but argument 2 has type ‘int *’
sort.c: In function ‘insert_sort’:
sort.c:75:...

You can read image files in your program in a standard way, if you want to write the reader yourself. wotsit.org is a good reference for this, as already mentioned.

Or you can use a library to...

ex_1.emotion_options = (char **)malloc(sizeof(char *[MAX_EMOTION_SIZE]));
That's uninitialized, so if you don't fill in MAX_EMOTION_SIZE elements of that array, then this will be freeing random...

Well, if you think it makes the program easier to understand, then what can I say? :)

I really do think that there must be a better way, but unless you post some real code I probably won't think...

puts("Give me input numbers, each separated by space."); //gcc error: puts was not declared within this scope
You need to #include <stdio.h>, because that's where puts() is located.


The current...

Sorry to go behind jephthah's back here, but if this is your original structure

So does Perl! In fact, you can do it with just one line, on the command line.
perl -pe 's/\s/g'
But that's beside the point.

Note that ssharish's code works, but it might be more efficient to...

It seems to me that .h files would be better for this, if all you're doing is managing constants (and not actual executable code).

The standard place to include header files, of course, is at the...

Don't forget Dev-C++: http://bloodshed/net/devcpp.html

But I doubt that's the problem, if Ancient Dragon encountered the same issue.

Well, if

then you're out of luck, because, as you say, those numbers could not fit into a 32-bit integer.

On the other hand, if you want one of your structures as the result . . .

If the...

case 'R':
case 'r':
Key_r();

case 'S':

Something like this. I've glossed over details that you seem to already understand.

Declare an array to hold the letter counts one element for each letter, with each element initialized to zero....

Use code tags when you post code -- otherwise it will be an unreadable mess.

This is also the C programming forum, not the C++ one, so C++ code is out of place.

It's also old-style C++ code....

gotoxy() is an ancient Borland function. It's very unportable. No new code should use it or anything from <conio.h>, such as getch() or clrscr().

if(letter[i]==str[count])
Think about what you are doing here. You're saying something to the effect of, "if the i-th element of letter[] equals the count-th element of str[] ...". Since you've...

Perhaps you should have a look at this. http://en.wikipedia.org/wiki/Floating_point#Normalization

TRUE is a commonly-defined constant -- windows.h defines it, along with a whole host of other libraries. true is a C++ keyword, and a C99 keyword if you include <stdbool.h>.

So in ordinary, ANSI...

Not quite. That only works if you had gone one past the maximum allowed value. If you can add more than 1, you need to do this:

If you can add more than the maximum range -- in other words, if you...

You can also set the arguments to your program without actually running the program, such as right at the beginning before you forget, with "set args parameters". This is also the easiest way to...
