Algorithms Quiz | SP2 Contest 1 | Question 6
Predict the output of the below C program:
#include <stdio.h>
int main()
{
int a = - -3;
printf ( "a=%d" , a);
return 0;
}
|
(A) a=3
(B) a=-3
(C) a=2
(D) None of the above
Answer: (A)
Explanation: Notice the space between the two minus(-) operators. Here unary operation minus(-) is applied twice instead of the pre-decrement operator, we know in maths that minus*minus gives plus. Therefore, – -3 = -(-3) = 3.
