Translating C numerical operators to Java Boolean operators

Question

I have the following C code. I want to write a Java version of the C condition but I don't know what boolean operators the C numerical operators represent in the if statement.

The C code is:

if ( (n >= 1) * (n < 10) + (n == 0) )
{
     printf("A\n");
}
else
{
     printf("B\n");
    }

    return 0;

What boolean operators do * and + translate to?

Answer 1

You can figure this out by looking at their truth tables. Keep in mind that in C, 0 is false, and any other value (including 1) is true.

 *  | 0 | 1      +  | 0 | 1
    |   |           |   |
 ---+---+--      ---+---+--
 0  | 0 | 0      0  | 0 | 1
 ---+---+--      ---+---+--
 1  | 0 | 1      1  | 1 | 2

In case this is a homework question, I will leave the rest to you. If you need more hints, Google for "boolean operation truth table".
