A computer program is designed to perform calculations involving integers. If variable 'x' is assigned the value 15 and variable 'y' is assigned the value 3, what will be the result of the expression 'x % y'? (Here, '%' represents the modulo operator).
सही उत्तर: ख) The modulo operator (%) gives the remainder of a division. In this case, 15 divided by 3 is 5 with a remainder of 0. Therefore, the correct answer is 5.
The modulo operator (%) returns the remainder after division. When 15 is divided by 3, the result is 5 with a remainder of 0. Option B represents this correctly.

Consider an 8-bit data word. If the most significant bit (MSB) is set to '1', what is the range of possible values that can be represented?
सही उत्तर: ख) 0 to 256
An 8-bit data word can represent 2^8 = 256 distinct values. When the MSB is set to '1', the range of representable values spans from 0 to 255 (inclusive) because it's using one bit for the sign and the remaining 7 bits for magnitude.
