Chapter 7, Problem 46E
Program Plan Intro
Computer problem-solving model:
The phases present in the computer problem-solving process is given below:
- First phase: Analysis and specification phase
- In this phase, analysis defines the problem and specification means identifying the problem that users trying to solve it.
- The output of this phase defines the problem statement.
- Second phase:
Algorithm development phase- This phase develops a logical sequence of steps which are used to solve a problem.
- In this phase, testing algorithm is used to check whether the given solution is able to solve the problem or not using the given sequence of steps.
- The output comes from this phase is make a general solution to the problems that are specified in the analysis and specification phase.
- Third phase: Implementation phase
- This phase is used to convert the algorithm that is provided by second phase into a
programming language. - The output of this phase is a working computer program that implements the algorithm that is given by second phase.
- This phase is used to convert the algorithm that is provided by second phase into a
- Fourth phase: Maintenance phase
- This phase is used to maintain the program.
- User needs to modify the program if any error occurs in the code.
- If error or modifications occur in the program, the given problem is sent back to first, second or third phase based on the modification.
- The output is not produced from this phase.
- This phase is used to maintain the program.

That EFA takes 6 one bit inputs: aj, bj, Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit outputs: sj, Cout and rout. The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only on t₁ and to in the first place: t₁ to Description 00 Output Relationship Ignored Inputs Addition Mode 2 Coutsjaj + bj + Cin, Tout= 0 Tin 0 1 Shift Left Mode Sj = Cin, Cout=bj, rout = 0 rin, aj 10 1 1 Shift Right…arrow_forward

- Programming Problems 9.28 Assume that a system has a 32-bit virtual address with a 4-KB page size. Write a C program that is passed a virtual address (in decimal) on the command line and have it output the page number and offset for the given address. As an example, your program would run as follows: ./addresses 19986 Your program would output: The address 19986 contains: page number = 4 offset = 3602 Writing this program will require using the appropriate data type to store 32 bits. We encourage you to use unsigned data types as well. Programming Projects Contiguous Memory Allocation In Section 9.2, we presented different algorithms for contiguous memory allo- cation. This project will involve managing a contiguous region of memory of size MAX where addresses may range from 0 ... MAX - 1. Your program must respond to four different requests: 1.
