Chapter 10.1, Problem 12E
Program Plan Intro
To find the number of bytes that the computer uses for storing the address of different variables such as characters, integers, and a double-precision number using the sizeof() operator. Also, find whether the size of all is the same or not and provide the reasons for it.

7. Adding Them All Upby CodeChum Admin
Being the business-minded I am, I have a lot of sources of income. My money is getting out of hand and I don't know how much is the total now.
Can you please help me add them all up?
Instructions:
In the code editor, you are provided with a main() function that asks the user for 3 integers.Your task is to create 3 pointers and name them: a_ptr, b_ptr, and c_ptr. Then, assign the address of a to a_ptr, b to b_ptr, c to c_ptr. Make sure to do this before the printf statement found at line 16.Input
1. First integer
2. Second integer
3. Third integer

1. Write code to implement the expression: A =
on 3-, 2-, 1- and 0-address
machines. In accordance with programming language practice, computing the expression should
not change the values of its operands.
2. Solve the following:
a) In a computer instruction format, the instruction length is 11 bits and the size of an address
field is 4 bits. Is it possible to have:
5 2-address instructions, 45 1-address instructions and 32 0-address instructions using the spec-
ified format? Justify your answer.
3. Suppose a computer using direct mapped cache has 232 bytes of byte-addressable main memory
and a cache size of 512 bytes, and each cache block contains 128 bytes.
a) How many blocks of main memory are there?
b) What is the format of a memory address as seen by cache, i.e., what are the sizes of the tag,
block, and offset fields?
c) To which cache block will the memory address 0x13A4498A map?
