Descending Order Check

Write a program to find whether the given array is sorted in descending order.

Input Format:

Input consists of n+1 integers. The first integer corresponds to ‘n’ , the size of the array. The next ‘n’ integers correspond to the elements in the first array. Assume that the maximum value of n is 15.

Output Format: 
Print yes if the array is sorted in descending order. Print no if the array is not sorted in descending order.

Sample Input 1: 
 5
 2
 3
 6
 8
 1
 Sample Output 1: 
 no

Sample Input 2: 
 5
 20
 13
 6
 4
 1

 Sample Output 2: 
 yes

Code

  #include<stdio.h>
int main(){
  int a[15],i,flag=1;
  int n;
  scanf("%d",&n);
  for(i=0;i<n;i++)
  {
    scanf("%d",&a[i]);
    if(i>0)
    {
      if(!(a[i-1]>a[i]))
        flag=0;
    }
  }
  if(flag)
    printf("yes");
  else 
    printf("no");
  return 0;
