Hi,

I'm not clear as to when memory is allocated from the stack, free store or data area.Can someone please elaborate?

I've somehow managed to fix that error through a sequence of attempts but cant figure out what fixed it. :| But the error was actually in another malloc. thanks to valgrind.

I'm stuck in another...

Thanks.I'll try them both.

wow..ok..the malloc casting was out of habit.I'll stop doing that

Second, are these the ONLY malloc calls in your code, or are there others?

that doesnt seem to be the problem. The input to the function short int *waveform was initialized in a similar manner.It didnt cause a problem.

I've included stdlib,no problem there.
Yes.It is an array of short ints
Here is the entire function


RiffWaveFile and RiffHeader are structures as follows.

Hi,
I need an array of approx. 2,00,000 elements.But malloc fails to allocate beyond 65872.
When I give
(short int*)malloc(sizeof(short int)*65000);
It works but seg faults when I give
(short...

ok...It was the return value! thanks a lot! memory leaf fixed :P

Hi,
Here's my code

Hi,
I'm implementing kd trees and have pseudo code for most of the functions but the delete operation.Its quite complicated and I have no idea how to implement it.Any help is appreciated

Hi,
I'm new to php.I had to include common content to a lot of webpages in my website like menubar etc. and i was told i could load them dynamically from a single file using php.Can someone help me...

2. no..theyre messed up.
it says -52,0,0

1. BRILLIANT!

i used a temp variable for the sprint f and it worked!!!!!!!! thanks a ton!

I have a code snippet that strangely works one way on a fedora 6 machine and another way on a fedora 8 machine.


void Form1::SendToApp()

I have a c++ program that performs a functionality.
generate.h

struct code
{
bool out;
bool *reg;
};

class Cyclic

still need help with this :(

Thats what I'm saying too.Let me explain bit erasure.

Lets say I transmit 01001101
theoretically, I recieve 01?01?01
ie. I dont know those bit values...though I'm in doubt now how thats even...

Hi,
In an assignment I'm supposed to introduce packet errors and bit erasures in the packets.packet errors I can do.Bit erasures mean we have no idea if its a 1 or a 0.how can I introduce something...

Thanks a lot! :D

hey..I need to convert a 8 value bool array to char.How can I do this?

Hi,

I need help with implementing cyclic codes.Its much like crc.I've found a lot of software implementations for crc but havent understood them.I've looked at a crc guide which gave,

So to...

I wrote the server and client programs.I'm sending data from server to client.

Server

Hi,

I want to transfer a file as it is via a socket...not read the file contents and send it.How can I do this?

expression parser that handles polynomials?

I'm actually implementing something similar to a CRC..I need to use one of the factors to divide a message and get the remainder...any help with this is appreciated

Hi,

I need to write C++ code to find the factors of a polynomial.For eg. X^2-1 should return x-1 and x+1...anyone have any ideas on how to do this?

Hi,

I'm implementing linear block coding and need some ideas on how to go about storing the cosets.

i.e.
If i have an alphabet C={000,101,010,111}
I need to perform
C+000={000,101,010,111}...

Hi,

I've got a program that I wish to run in a powerful server so that it can run on several cores simultaneously and work faster.I need to do client server programming for this.That is, I recieve...

Hi,

We are doing some audio data collection.So I need to write a program which when run would generate a beep and record from a microphone until the next beep and save it as a wave file.This...

Hi,

Thanks to everyone I was able to submit my huffman coding assignment successfully.Now I've got to do arithmetic coding and it seems really confusing.I've looked at arturo campos's page ...

I'm reading a file and I'd like to get short,int etc. apart from the usual char because I want to read 16 bit values...is there a way?

Its solved...it had to do with a declaration..thanks

I only use new and delete and Im not freeing anywhere else except my destructors...which I commented and I still get the error...what other possibilities exist?

I'm getting this error at the end of my program...

*** glibc detected *** ./a.out: free(): invalid pointer: 0x00617ca0 ***

Hi,

Whenever a user types ./a.out with the wrong number of arguments I want my program to output something like
Usage: ./a.out <-e/-d> <FIlename> <Value>

how can I do this?

passed the file pointer..the seg faults stopped :)

thanks

Hi,

In a function of my program, I open and close the file once every recursion...and the recursion is very large....I've made sure im not writing when its closed or not opening when its open or...

yes...everything else is ok...only this character is being skipped

I'm coding pdf files...and its appearing within the file...not at eof

I'm sorry..i mis read my files...its actually skipping a "ÿ" from the input files...and ÿ is not in my tree
