Hello everyone
(this is my first post)Im working in a Word Cound program where I need to insert every new word in an array,first i calc the number of words (which is 113000) then i use calloc to allocate this array but i get a seg error every time, can someone help me with this mess...
thx 4 reading

Can you post the code you're trying to use? Specifically the initialization and population of the huge array?
Thx for the quick reply.The initialization of the array is:
char**array1=(char**)calloc(113000,sizeof(char));
Don't cast the return value of calloc()/malloc(). If you #include <stdlib.h> and are actually using a C compiler to compile your C code then you won't get any warnings.
Also, a pointer is not the same size as a char. Your second argument to calloc() should be sizeof(char *). That allocation just creates room for the pointers to your words. Then you'll need to allocate more memory for each of your words (the length of the word + 1 is a good amount of memory to allocate for that).
If you understand what you're doing, you're not learning anything.
Ok, the problem is that you're trying to initalize an array of arrays using a function call that just returns memory for a single array. What you need to do is this.
There's also something you need to do to initialize the char** array, and that needs to be done before the code sample above, but I don't remember how to do that.Code:char** array[how many arrays][size of each array]; for (int x = 0; x < [how many arrays]; x++) { array[x] = (char*)malloc([size of each array]); }
Basically, you first need to allocate memory for the array of arrays, and then you need to allocate memory for each one of the arrays within the array of arrays. That's why you're getting the error.
Thank u very much people i'll try to work on that and i'll give u the feedback.
