Question

Consider the following code:
#define SQ(a) (a*a)
int answer = SQ(2 + 3);
What will be the value of answer after the above code executes?​

Answer 1

Answer:

The output of the code will be 25

Answer 2

Answer:

The answer is 25.

Explanation:

i) The given code can be converted to a mathematical function as:

f(a) = a x a

ii) The value of this function at given value of 'a':

f(2+3)= f(5) = 5 x 5 = 25.

iii) Hence, the value of answer after the execution of code will be 25.
