Question :

What is the output of the following program?

#define SQR(x) (x*x)

main()

{

int a,b=3;

a= SQR(b+2);

printf("%d",a);

}

Answer:

The ans is B(11).

Since it passes like (3+2) to #define, where it calculates as

(3+2 * 3+2), as Ist preference is multiply & then addition, it evalvates as

(3+ 2 * 3 +2) = (3+6+2)=11.
