C program to print numbers in descending order

C program to print numbers in descending order

Output:

Enter the number of elements:
10
Enter the elements to sort:
1 2 3 4 5 6 7 8 9 10
The numbers in descending order:
10 9 8 7 6 5 4 3 2 1

Implementation:

#include <stdio.h> #include <stdlib.h> void swap(int *x,int *y) { int temp; temp=*x; *x=*y; *y=temp; } int main(void) { int n,*a,i,j; printf("Enter the number of elements:\n"); scanf("%d",&n); a=(int*)malloc(sizeof(int)*n); printf("Enter the elements to sort:\n"); for(i=0;i<n;i++) { scanf("%d",(a+i)); } /* sorting the numbers in descending order */ for(i=0;i<n-1;i++) { for(j=i+1;j<n;j++) { if(a[i]<a[j]) { swap((a+i),(a+j)); } } } /* printing the sorted elements */ printf("The numbers in descending order:\n"); for(i=0;i<n;i++) { printf("%d ",*(a+i)); } return 0; }
