Thread: String Compare manual built

Hi, I just tried to make a manual Comparing strings by using this code:

Code:

int compare(const void* i, const void* j);
int main()
{
	int i = compare("hi", "hi");
	printf("%d", compare);
}
int compare(const void* i, const void* j)
{
	return (strcmp(*(char**)i, *(char**)j));
}

it doesn't work!, any help? another thing I'm still confusing on type casting a variable (char**) i , can someone explain me it ?! thanks

Have a closer look at line 5.
Do you want to print the address of the compare function?

There is no need for casting:

Code:

int compare(const void* i, const void* j)
{
    return strcmp(i, k);
}

Of course you could write it like this:

Code:

int compare(const void* i, const void* j)
{
    const char *cp1 = i;
    const char *cp2 = j;
    
    return strcmp(cp1, cp2);
}
