Here is the prototype of the function:
void fillTopoArray(string topoFileName, int topoGraph[MAX_VERTICES], int *nodeCount, int *edgeCount);
Here is how the parameter passed to the...

I have a function such that one of its parameters is a 2D array of type int. The parameter is defined as follows:
int topoGraph [MAX_VERTICES]

Thank you very much.
Yes - that is the point that I was missing.

Below are two functions:
void printGraph(const int* topology, int dimSize)
for(int rowIndex = 0; rowIndex < dimSize; rowIndex++)
for(int columnIndex = 0; columnIndex <...

After passing the address of the first element (&array) of a multi-dimensional integer array to a function with a "const int*" parameter, parameter seems to be pointing to the wrong...
Following function obtains the system-maintained structure for a message queue:
bool getMessageQueueStats(int mqId, struct msqid_ds* buf)
if(msgctl(mqId, IPC_STAT, buf) ==...
No, there is no reason - It's just bad programming.
When does an invalidation of a pointer take place ?
I think that it depends on the layout of the memory at a certain time.
Hence, even for...
Given the following piece of code in D.cpp :
//set string myString
//set boolean myBoolean2 and myBoolean1
bool marked = false;
Given the following line numbered 780 in my_daemon.cc:
valgrind generates the following invalid read error:
This problem seems to be weird.
At one execution of my program, time increment works fine, but on another run of my program at a later time, it does not. (I run it with the same user)
My question was something else.
Can you imagine any factor which may cause gmtime() or localtime() functions to behave differently for the same input at different times ?
That is, I sometimes...
To give an example to false looking result of gmtime(), given the following year/month/day/hour/minute input:
The result returned by gmtime() is:
Following C++ function is expected to add 5 minutes to a certain date and time in "Broken-down time" format, and output the new date and time in the same format again:

I think that it is not legitimate to erase entries in a map in the following way:
//fill in temp here

Using C++, I want to process sub-folders on my home folder sequentially each with a special naming format and containing some binary files in it:

This is much better.

What do you think about the function below ?
const char *BEGIN = dataStream.str().c_str();
const char *END = dataStream.str().c_str() +...

Sorry, I admit that my question was not clear.
If I have the following binary stream in hex representation:
00 01 02 03 00 00 04 05 00 00 00 06 07
what I want is to obtain the size of...

Is there any function in C++ 's standard library or in STL which gives the number of consecutive characters in a stringstream object ?
std::count() and strspn() do not seem to be what I...
Following function utilizing boost's string tokenizer class crashes as might be expected:
bool CheckCommand(const string& cmd, const string& line)
if (line.length() == 0)...
Let me clarify the reason why I posted this thread.
Assuming we have following "u_char" binary data (call it myData) with hex representation of size 23 bytes :
55 11 93 2b 55 6a 56 5c 60 2d...
All the sizes for data types that I listed in my posting have been verified to be correctby using sizeof() statements.
I want to define a C-struct as shown below, which will be written to a message queue:
struct in_addr addr1, addr2; // 4-byte
u_int32_t s; ...

So the following code snippet will do the job:
const char *BEGIN = buffer;
const char *END = buffer + 1000000;
size_t numberOfNullChars = count(BEGIN, END, 0);

What if I want to count for the number of NULL characters in a char array ?
Given the following value for buffer with no terminating null character:
buffer = 'a'
buffer = 0...
