#include <stdio.h>
#include <conio.h>
void main()
{
  int x, y, z, temp, small;
  clrscr();
  printf ("Enter the value of 3 numbers: ");
  scanf ("%d%d%d", &x, &y, &z);
  temp = (x < y)    ? x : y;
  small =  (z < temp) ? z : temp;
  printf ("The Smallest of this 3 numbers: %d", small);
  getch();
}

Output:
