Thread: Bugging ... Compile Time Error

I dont know whats terribly going wrong with this, well I know there's some memory allocation with this but I tried hard to fix it and when it gets fixed it doesn't shows up the desired value, this is the code that shows the compile-time error:

Code:

#include <stdio.h>
#include <string.h>

#define $WORD_LIST(X) "resource/" X

typedef struct char_type
{
	char** ptr;
}ccarray;

int ccarray_create(ccarray *c)
{
	c = (ccarray*)malloc(sizeof(ccarray*));
	
	c->ptr = (char**) malloc(sizeof(char**) * 1024);
	return 0;
}

int ccarray_insert(ccarray *c, char* str, int pos)
{
	c->ptr[pos] = str;
	printf("%d %s\n", pos, c->ptr[pos]);
}

int ccarray_destroy(ccarray *c)
{
	free( c->ptr );
	free( c );
	return 0;
}

int ccarray_read_file(ccarray* c, char* filename)
{
	FILE * fptr;
	char* line;
	int i;
	
	fptr = fopen(filename, "r");
	line = (char*) malloc(sizeof(char)*100);
	i = 0;
	
	while( fscanf(fptr,"%s",line) != EOF )
	{
		ccarray_insert(c, line, i);
		i++;
	}
	free(line);
	fclose(fptr);
}

int ccarray_print(ccarray* c)
{
	int i = 0;
	while ( c->ptr[i] != NULL )
	{
		printf("Line: %s\n", c->ptr[i] );
		i++;
	}
}

int main()
{
	ccarray * c;
	ccarray_create(c);
	ccarray_read_file(c, $WORD_LIST("sample.txt"));
	ccarray_print(c);
	ccarray_destroy(c);
	return 0;
}

... and this thing runs fine but doesn't shows any result:

Code:

#include <stdio.h>
#include <string.h>

#define $WORD_LIST(X) "resource/" X

typedef struct char_type
{
	char** ptr;
}ccarray;

int ccarray_create(ccarray **c)
{
	(*c) = (ccarray*)malloc(sizeof(ccarray));
	(*c) = (ccarray*)malloc(sizeof(ccarray));
	(*c)->ptr = (char**) malloc(sizeof(char**) * 1024);
	return 0;
}

int ccarray_insert(ccarray **c, char* str, int pos)
{
	(*c)->ptr[pos] = str;
	//printf("%s ", (*c)->ptr[pos] );
}

int ccarray_destroy(ccarray **c)
{
	free( (*c)->ptr );
	free( c );
	return 0;
}

int ccarray_read_file(ccarray** c, char* filename)
{
	FILE * fptr;
	char* line;
	int i;
	
	fptr = fopen(filename, "r");
	line = (char*) malloc(sizeof(char)*100);
	i = 0;
	
	while( fscanf(fptr,"%s",line) != EOF )
	{
		ccarray_insert(c, line, i);
		i++;
	}
	free(line);
	fclose(fptr);
}

int ccarray_print(ccarray** c)
{
	int i = 0;
	while ( (*c)->ptr[i] != NULL )
	{
		printf("Line: %s\n", (*c)->ptr[i] );
		i++;
	}
}

int main()
{
	ccarray * c;
	ccarray_create(&c);
	ccarray_read_file(&c, $WORD_LIST("sample.txt"));
	ccarray_print(&c);
	ccarray_destroy(&c);
	return 0;
}
