check the greater number among the three numbers in cprogramming

#include<stdio.h>
void main()
{
       int a,b,c;
printf("Enter first number :");
scanf("%d",&a);
printf("Enter the second number :");
scanf("%d",&b);
printf("Enter the third number :");
scanf("%d",&c);
if(a>b&&a>c)
{
    printf("first number  %d  is greater number",a);
}
else if(b>a&&b>c)
{
   printf("second number %d is greater number",b);
}
else
{
  printf("third number %d is greater number",c);
}
  getch();
}

output:

    Enter first number  :14

   Enter second number :56

   Enter third number :45

  second number 56 is the greater number
