Thread: Getting garbage after I malloc space...

So my goal is to get the name of the directory by itself.
But when I print it at the end, I get the name + some garbage.
I don't understand why, since I am malloc'ing the right amount of characters...

Code:

int main () {
	char address[] ="./testrun/forfun";
	char *dirName;
	char *pch;
	int i = 0, lastslash = 0;

	pch = strrchr(address, '/');
	lastslash = pch - address + 1;
	pch = NULL;
	dirName = (char *)malloc(sizeof(char) * (strlen(address) - lastslash));

	while (address[lastslash] != '\0'){
		dirName[i] = address[lastslash];
		i++;
		lastslash++;
	}

	printf ("%s\n", dirName);

	return 0;
}

Would somebody help me?
I have tried doing realloc on dirName inside the while and all, but it doesn't like that either...
