printf("%d",a[i]);

}

Answer / shruti

The above solution is ritee.. :-)

cheers..

Answer / arpit dhandhania

Both the solution above is wrong...

Answer #1: It will input an extra element in array coz array is starting from 0 and goes till n so total elements n+1

Answer #2: C Automatically starts array from 0 index and not 1 if not programmed otherwise and in the given program we are starting the loop from 1

Solution

void main()
{
int a[30],n;
scanf("%d",&n);

for(int i=0;i<n;i++)
scanf("%d",&a[i]);

for(i=n-1;i>=0;i--)
printf("%d",a[i]);

}
}

if( n%2 == 0 )
c = n/2 - 1;
else
c = n/2;

for ( j = 0 ; j < c ; j++ )
