Answer 1

It's a very famous quiz question. For this you should keep in mind that #define allows you to make text substitutions before compiling the program.
So the following program can be read like this during the time of compilation:-

int x = 16/4 * 4
printf("%d",x)

So according to this, output should be 16

Answer 2

o/p : 16

x=(16/4)*4=4*4=16
