Have you figured out how to sort a 1-D array using your own comparison function, and the standard library qsort() function?

It's exactly the same method, the only trick is getting the compare function declared properly.

#define SIZE 100
void Sort(char arr[SIZE][SIZE], int NoOfRows) {
	int i=0,j=0 ;
	char temp[SIZE] ;
	for(i=0;i<NoOfRows;++i) {
		for(j=0;j<NoOfRows;++j) {
			if(0 > strcmp(arr[i],arr[j])) {
				strcpy(temp,arr[j]) ;
				strcpy(arr[j],arr[i]) ;
				strcpy(arr[i],temp) ;
			}
