(T/F)
1) A struct in the C programming language is a composite data type (or record) declaration that
defines a physically grouped list of variables to be placed under one name in a block of memory,
allowing the different variables to be accessed via a single pointer.
2) In C, a struct can be returned value of a function.

, 3) In C, it is possible to pass a struct to a function by its pointer and get it modified by the
function. correct answers True
True

L6
Which one is bit 23 mask (BIT23)? correct answers (1<<23)

L6
A single-bit bitmask is a bitstring where all the bits are 0 except for a single bit, which is 1. If
that single bit is located at index i, we call the bitmask BITi. For example, BIT0 is equal to 1 and
BIT1 is equal to 2 and BIT2 is equal to 4, and so on. If we intend to reset bits 10 and 20 of an
integer, and we like to create a macro mask, what should go in the blank space below?. If we
intend to reset bits 10 and 20 of an integer, and we like to create a macro mask, what should go
in the blank space below?

#define NEW_MASK ....
x = x & ~NEW_MASK;

A. (BIT10 | BIT20)
