52: If the following program fragment(assume negative numbers are stored in 2's complement form)
unsigned i=1;
int j=-4;
printf("%d",8*size of(int));
output is (log in answers are to the base two)

A.	An unpredictable value
B.	8*log(x+3)
C.	log(x+3)
D.	None of these
	Answer Report Discuss
	Option: C Explanation : Let size of (int)=1. So, -4 will be stored as 11111100. Since we are adding unsigned and signed integers the signed gets converted to unsigned. So, i + j will become 11111101. We are trying to print this as an unsigned integer. So, what is printed will be 2⁸-1-2. So, log (x+3)=8(i.e,size of (int)).
