It may seem overkill, but the first thing to do is to sort them.

C

#define swap(x, y) do {int tmp; tmp = x; x = y; y = tmp; } while (0)
int getMiddleNumber(int a, int b, int c)
   {
   if (b < a) swap(b, a);
   if (c < b) swap(c, b);
   if (b < a) swap(b, a);
   return b;
   }

Then all you have to do, is use b - it is in the middle.
(this code pinched from here[^])

"Using macros like that (while convenient) is generally frowned on. You can't debug a macro, so you have to hope your code is right."

Agreed, but it's been quite a while since I used straight C and I couldn't remember where I put my QuickC disks... :laugh:

C#

void swap(int *x, int* y)
   {
   int tmp; 
   tmp = *x; 
   *x = *y; 
   *y = tmp;
   }
int getMiddleNumber(int a, int b, int c)
   {
   if (b &lt; a) swap(&b, &a);
   if (c &lt; b) swap(&c, &b);
   if (b &lt; a) swap(&b, &a);
   return b;
   }

I would not suggest sorting. In this case it might work well. But as the list increases, the complexity increases. The best way to use is to use two variables, one to store the largest, and the other to store the second largest. Then traverse through the array from first to last and compare its value with those two variables and at last you'll get the second largest variable in the second variable.

I want to find second highest number from the three numbers x,y and z using C language if(y>xz) then x, if(xz||x>yy||x>z<y) then z
