Question
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
Output
Enter·a:·1Enter·b:·6Enter·c:·3Total·=·10
(a) Given that a pointer is a variable that references the memory address of another variable,
how do we declare, assign, and initialize pointers? Explain in full detail, by describing the
operator that gives us access to a variable's location in memory.
(c) Does an integer pointer store an integer itself or something else?
(d) What is the purpose of pointers? What do they allow us to do? What would happen if we
didn't have pointers?

Now that I'm knowledgeable about pointers, I'm going to point all of my 5 fingers to them. Let's see who's tough now! Instructions: In the code editor, you are provided with a main() function where the user is asked for 5 double numbers.Then, in lines 19 - 23, your task is to set the addresses of these numbers to each of the pointers. The address of the first number, a, should be assigned to the first pointer, the address of the second number, b, should be assigned to the second pointer, and so on.Input 1. First number 2. Second number 3. Third number 4. Fourth number 5.

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?arrow_forward
