char cc = 255;
if(cc == 255)
printf("cc equal to 255");
printf("cc not equal 255");
Answer: cc not equal 255
The line cc = 255 will give a warning but not an error in C.
After execution of this statement, value of cc will be -1. Char variable takes 7 lower bits as magnitude and the most significant bit as signature. In this case, all bits including the signature bit is 1 which makes it a negative number. The value of the negative number may be calculated as shown below:
cc = Negative signature( two's complement of binary 1111111)
= Negative( not of binary 1111111 + 1)
= Negative( 0 + 1)
