I don't know jack about Visual Studio, and I'd like to keep it that way because I like doing stuff on the command line, I have my preferences. But my teacher uses it to compile and I'm curious what I did wrong because gcc didn't throw anything. So, code (Without …

Hi everyone well currently I am working on a simple malloc and free implementation but I am facing some problems . I get a segmentation fault this is my output inserting node 0 0xc87000 inserting node 1 0xc87014 inserting node 2 0xc87028 inserting node 3 0xc8703c inserting node 4 0xc87050 …

Hi. Sooner or later I had to go into the depths of C. Today was the day I tried my first things with C. However, I am having a problem although I do not know what actually causes it. The goal of the pogram is to combine the parameters into …

My program begins by opening a dictionary file, the first line of which contains the number of words in the dictionary. If I print the words immediately after scanning them into the arrays, they appear fine, but if I later examine a previous entry, I can see it has been …

I am having trouble correctly allocating memory for a parent function that will remain upon the child functions exit. the call to the child function is [code=c]HTTP_packToGen((char*)http_headerContent.HTTP ..[/code] the HTTP variable within http_headerContent is a char pointer that isn't allocated until the child function is called, http_headerContent is a static …

Hello, This is an extension of this thread: [url]http://www.daniweb.com/software-development/c/threads/357681/1525001#post1525001[/url] My purpose is to create a class that handles a network message.

HMm... already frustrated at it... But is there something wrong in my malloc? Everytime I try to display the record, it gives me random things as answer(see code below)? Was it that I didn't free it or was I wrong in declaring malloc itself? Thanks in advance. [CODE] #include <stdio.h> …

Hi, This is probably, a really novice question, but I have some code that is using the malloc() function to declare an array, the problem is that I am using a special compiler to compile code for hardware which gives me a lot of errors because of the stdlib.h header …

I have basic idea about malloc and calloc i heard about falloc and dlmalloc, can any one explain about it?

I've a 2-d array declared as such [CODE]lower_tri = (float **)malloc(sizeof(float *)*(dimention)); for(i =0; i < dimention; ++i) lower_tri[i] = (float *)malloc(sizeof(float)*(i+1));[/CODE] So that it looks like... [] [][] [][][] [][][][] ... However, it causes a segmentation fault when I try to de-allocate the array with [CODE]free(lower_tri);[/CODE] (only in unix, …

Hi, I am attempting to create a dynamic array using realloc in 2 dimensions. Currently i have managed to get it to work using realloc to dynamically resize the amount of rows but when I attempt to use realloc to dynamically resize the amount of columns per row I keep …
