Software Lifecycle & Algorithm Design in C++: A Comprehensive Guide

This course covers the software life cycle, top-down design method for algorithm creation, C++ algorithm implementation, program documentation, Unix homework, textbook usage, WPI system log-on/off, editor familiarity, and relevant textbooks. Understanding main and secondary memory, central processing units, instruction sets, and assembly language basics, such as opcode and data structures. Learn the assembly language, register operations, CPU functions, and data handling. Follow detailed programming instructions and examples from the textbook "C++ How To Program" by H.M. Deitel.

Presentation Transcript

  1. CS1005 • Become familiar with the software life cycle. • Be able to design algorithms to solve problems, using the top-down design method. • Demonstrate the ability to implement algorithms in C++. • Be able to write appropriate program documentation, and to adhere to a documentation standard. • Gain experience with Unix

  2. Homework • Get the textbook • Know how to log on/off WPI system • Learn how to use an editor • Read chapters 0 and 1 • Look at website for this course • Put all due dates in your planner

  3. Main memory • Volatile (lost when computer turned off) • Limited in size (costly) • Provides fast transfer (CPU – memory, memory – CPU) • Only data in main memory can be processed by the CPU

  4. Secondary memory • Data permanent until you change it • Unlimited size • Portable • Slow transfer rate compared to main memory

  5. Central Processing Unit • Brings info (data and instructions) from secondary memory to main memory • Processes (transforms) data • Stores results in secondary or main memory

  6. Instruction Set • Arithmetic operations • Comparisons • Transfer of control (jumps) • Transfer of info from one place to another • I/O operations

  7. Register R1 Register R2 Add the contents of R1 to R2 and Leave the result in R1 Each instruction is 2 bytes in length. The first byte is the opcode, the second byte contains data which varies according to the opcode Opcode = 10111011 Data = 0001 0010

  8. Assembly Language • Is different for each type of computer • Requires that the programmer think like a computer • Is tedious and detailed • Very cryptic

  9. A = B + C R1 66 00000011 C contains 3 65 00000010 B contains 2 64 00000000 A contains 0 R2 7 01000000 Program Counter (PC) 6 10111101 STORE (A), R1 5 00010010 4 10111011 ADD R1, R2 3 01000010 2 10110110 LOAD R2, (C) 1 01000001 0 10110101 LOAD R1, (B) Instruction Register (IR)
