Bitwise Operations
1. Write a function that has an int parameter n, makes an integer mask having the bit 1 at the nth place from the rightmost bit, and returns the mask. For example, when n = 5 is passed to the function, the function will return 0x20 (Note that 0x20 is 00000000 00000000 00000000 00100000). 2. Write a function that has two int parameters num and n, and returns TRUE when the nth bit in num is 1, otherwise FALSE. This function should use the function in the above problem (1). (Be careful how to handle Boolean values in C.)3. Write a function that has a single int parameter n and returns an int: 0 if n is negative, otherwise 1. You are not allowed to simply check the integer value, and should use the function in the above problem (2). 4. Write a function that has four unsigned char parameters, combines the four one-byte integer values into an unsigned integer, and returns the unsigned integer. When the four one-byte integers are combined, the first value must be used for the first byte in the resulting unsigned integer, the 2nd value for the second byte, the 3rd value for the 3rd byte, and the 4th value for the last byte. 5. Write a function that has int parameter n, makes another type of mask having n bit 1's from the left most bit and 32- n bit 0's next. The mask is called netmask in this seminar, and the function will return the netmask. (Note that a netmask consists of two parts of bit 1's and bit 0's.)6. Write a function that has two unsigned int parameters of an IPv4 address (i.e., an unsigned int) and a netmask (i.e., an unsigned int), and returns the network id part in the IPv4 address. (Note that the network id part in an IPv4 address is obtained from the address by clearing some bits that are indicated by the bit 0's in a netmask.)7. Write a function to check odd-parity of a given int parameter. That is that the function returns 1 when the number of bit 1's is odd, otherwise 0.8. Write a main function that tests all the functions in (1) - (7).
