Re: How to Sort a MultiDimensional Array

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.

If your are trying to sort a MultiDimensional array of character you can see this. this is simple bubble sort

C Syntax (Toggle Plain Text)
#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) ;
			}
		}
	}
	return ;
}
#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) ;
			}
		}
	}
	return ;
}
