Thx for the clarification. The following works now



#include <stdio.h>

int main(void)
{
// you need malloc otherwise memory error.
char* string=(char*)malloc(5);

This works.



#include <stdio.h>

int main(void)
{
// you need malloc otherwise memory error.
char* string=(char*)malloc(5);

#include <stdio.h>

int main(void)
{
// you need malloc otherwise memory error.
char* string=(char*)malloc(5);
set(string);
printf("%s",string);
return 0;
}

THank you

Here what is the meaning of & used? THanks.

Thanks man. Don't call me wacko though. I was trying to create a tree like structure.

Fixing that small error it prints 123.

I did coding on galaxy tab. woot

Ok i'll look into it :o

Say you are in chat room and in it there are 3 users.
paul127, mary532, mark456
You type pau and press tab to automatically complete paul's user name. The following code prototypes that feature.

Thanks. I had to reset i and j to their original values inside while loop. Here's code returning "app" as expected after matching.

Thanks tc. I've tried your code.



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

int main() {
char buf[3][10]={"pine", "apple"};

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

int main() {
char buf[3][10]={"apple", "pineapple", "banana"};
char** ptr=(char**)buf;
puts(*ptr);
}

ok thanks ;)

Output gives blank line instead of "hello".

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

char* test(char* s) {
char ret[]="";
strcpy(ret, s);
return ret;
}

int main() {

free(ptr[1]);


This gives me either memory dump or seg fault. How to free ptr, ptr[0] and ptr[1] safely?

OK memory leaked so it can't free it.

This works.

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

int main() {
char string[]="apple";
char** ptr=(char**)malloc(2*sizeof(char*));
ptr[1]=(char*)malloc(10*sizeof(char));
...

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

int main() {
char** ptr=(char**)malloc(2*sizeof(char*));
ptr[0]=(char*)malloc(10*sizeof(char));
...

oh yeah i forgot to put malloc in line 26

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

typedef struct {
int value;
char* value2;
