Go4Expert - c input/output

Compiler bug probably. (-3) - (-3)=0 because any finite number minus itself is zero, so if your compiler thinks this is -6 then it's wrong. Similarly (-3) - -(-3) = (-3) - (3) = -6, not 0.

The answers are correct though, if transposed, so if the output is 0 -6 then that's correct. -6 0 would be wrong. To make certain, split the output with more detail to be sure:

Code:

printf("(-3) - (-3) = %d\n",a);

printf("(-3) - -(-3) = %d\n",b);

Visual Studio 2010 gets the correct answers.

Code:

void test49()

{

        int a,b;

        a = -3- -3;

        b = -3 - - (-3 );

        printf("%d %d\n",a,b);

        printf("-3- -3=%d\n",a);

        printf("-3 - - (-3 )=%d\n",b);

}

Output:

Code:

0 -6

-3- -3=0

-3 - - (-3 )=-6

The bottom line really is to stop using Turbo C 3.0, since it was written in 1842 by a Japanese caveman who had never seen a computer.
