#include <stdio.h>

int main (void)

{

     int num_1, num_2, num_3;

     int greatest;

     //Input numbers

     printf ("Input first number: ");

     scanf ("%d", &num_1);

     printf ("Input second number: ");

     scanf ("%d", &num_2);

     printf ("Input third number: ");

     scanf ("%d", &num_3);

     //Finding the greatest number

     if (num_1 >= num_2 && num_1 >= num_3)

          greatest = num_1;

     else if (num_2 > num_3)

          greatest = num_2;

     else

          greatest = num_3;

     //Print result

     printf ("Greatest number: %d", greatest);

     return 0;

};

Output

Input first number: 4

Input second number: 5

Input third number: 6

Greatest number: 6
