Thread: making a copy of an array by copying its address..

cant see why it works
ptemp=word[i];

i remember a thread of some user
that asked of ways to do a copy of an array.
and i suggested him to do this
thing.
and then i have been criticized by that "solution"
that we cant make a copy of an array just by assigning its address to other pointer
because (it cannot be copied or something like that)

Code:

int maxNum(char *str) {
	int i, j, max=0, count;
	for(i=0; str[i]; i++){
		count=1;
		for(j=i+1; str[j]; j++)
		if(str[i]==str[j])
			count++;
		if(count >max) 
			max = count;
	}
	return max;
}
void sort(char** word, int size){
	int i, j;
	char *ptemp;
	for(i=0; i<size-1; i++)
		for(j=i+1; j<size; j++){
			if(maxNum(word[i])<maxNum(word[j])|| 
(maxNum(word[i])==maxNum(word[j]) && strcmp(word[i], word[j])>0)){
				ptemp=word[i];
			word[i]=word[j];
			word[j]=ptemp;
			}
		}
}
