gcount returns 0

Those results were before the read.

After the read, open returns 1; good returns 0; end returns 1; and bad returns 0 (??)

myFile.is_open returns 1
myFile.good returns 1
myFile.eof returns 0

I'm trying to read the contents of a file using the ifstream constructs. I've written a program that is a carbon copy off the website, under Reading From a File:

C++ Binary File I/O

Thanks everyone :]

Hi all--

I'm writing a program that initializes an integer double pointer to NULL, and realloc's it's size each time a particular method is called. Something like:



int** list = NULL;
...

Got it. Thanks for the help, it's immensely appreciated.

That makes sense.

On the same token, why is:


1) char** stringArray = {"string1", "string2"}; //not allowed
2) char* stringArray[] = {"string1", "string2"}; //allowed


but

So I guess my question is: why are you allowed to assign a pointer to a string literal, and not a pointer of a double pointer to a string literal? (aka. char* strlit = "string" but not char**...

Think about obtaining the top section of the triangle, that is:

0
01
012
0123
01234
012345

How would that be accomplished?

I'm reasonably new to c and dynamic memory allocation really confuses me.

Take this code snippet:



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

int main() {

Brilliant! Thanks cas

Think of separating the problem into two halves: one for the top half of the triangle and one for the bottom half

Hi all--

This issue is completely perplexing me, the following is code that reads in lines from a file and is supposed to copy each line into an array:


235 ...

Thanks!

I'm working with code that grabs strings from a file and then works with said strings in different ways.

I would like to check if the first character in a char* is a #:



FILE* file =...

Why is it fundamentally better to use the syntax:


if(42 == answer)

as opposed to:


if(answer == 42)

Having made the aforementioned change I get the following error:

Undefined symbols:
"KeyValueComparator::operator()(KeyValuePair, KeyValuePair) const", referenced from:
_main in...

This has been driving me insane, and I'm not sure what's wrong:

I have a header file (KeyValueComparator.h):


#ifndef KEY_COMP
2 #define KEY_COMP
3
4 #include <string>
5 #include...

I have two char array variables:

char* key set to "foo"

and char* test set to "bar"

When I attempt a strcmp(key, test), my c program seg faults.

What's going on here?

Ok.

Does that method do what it is intended to do? Create a count_table_t pointer object and return it?

Hi--

I'm having trouble defining a method that is supposed to return a pointer to a struct:



count_table_t* table_allocate(int size)
{
count_table_t *test;
...
