}
else
{
printf("b is greater");
printf("\nThe value of b is:%d",b);
}
getch();
}

Answer 1

What is this (a-b) thing? Something is missing from the first if statement there, it doesn't make sense.

But i have a feeling that you try to print the greatest of two numbers, right? If so, then just modify the first if statement by replacing (a-b) with (a>b). It should work. Oh, and don't forget to check the case when the two numbers are equal.

Answer 2

we need to see the rest of the code, including the print statement.
