2D char array with dynamic mem allocation gives mem corruption
Hi guys,
Iam struck with 2D char array! Hope, you could help on this.
My requirement is, I want to add the string in string array and I dont know the size at compile time. Hence, have to use dynamic mem allocation.
Here is the code what iam trying..
Code:
void main(void)
{
char **name, string[100] = "Xyz String";
int i=0, n=25, index=0, numOfRows=1;
name = (char **)calloc(numOfRows, sizeof(char **));
for(i=0; i<n; i++)
AddStr(name, &index, string);
for(i=0; i<index; i++)
printf("--->%03d %s\n",i,name[i]);
for(i=0; i<index; i++)
free(name[i]);
free(name);
}
int AddStr(char **name, int *index, char *str)
{
int i=0;
//reallocating the mem for 2D row size as its incrementing every time. // NOT Sure, is this required or correct?
name = (char **)realloc(name, ((*index)+1) * sizeof(char **));
//allocating the mem for column for every row
name[*index] = (char *) calloc(strlen(str)+1, sizeof(char));
strcpy(name[(*index)++],str);
}
Pls. help to to solve this!
