#include <stdio.h>

int main (void)

{

               int number_1, number_2, number_3;

               //Input numbers.
               printf ("Input first number: ");
               scanf ("%d", &number_1);
               printf ("Input second number: ");
               scanf ("%d", &number_2);

               printf ("Input third number: ");
               scanf ("%d", &number_3);

               //Finding the greatest number and output the result.

               if (number_1 > number_2 && number_1 > number_3)
               {
                              printf ("First number is greatest."); 
               }
               else if (number_2 > number_3)
               {
                              printf ("Second number is greatest.");
               }
               else
               {
                              printf ("Third number is greatest.");
               }

               return 0;

};

Output

Input first number: 25

Input second number: 19
Input third number: 34

Third number is greatest.
