1-In C, what do the following mean, and what are the differences between them:

a) || versus |

b) && versus & (the binary operator)

c) ! versus ~

d) & versus * (both found in front of an identifier or variable name)

e) ++a versus a++

2- Give 2 examples of an embedded system.

3- Consider an 8-bit char named inchar. The least significant bit is called bit 0 and the most significant bit is called bit 7. Write one line of C code to do each of the following steps.

a) Set bits 1, 3, and 7 to 0 without affecting any other bits. (That is, clear these bits.)

b) Set bits 0, 4, and 6 to 1 without affecting any other bits. (That is, set these bits.)

c) Invert (toggle) bits 2 and 5 without affecting any other bits.
