  3. Course Objectives • Develop algorithmic problem solving skills • Understand modern software engineering techniques for the design of program solutions • Learn the ANSI C programming language

  4. Course Overview • Introduction to computers & programming • Problem solving; variables; expressions, printf • Top down design; functions • Selection structures; if and switch statements • Repetition and loop statements

  5. Course Overview • Modular programming • Data types and operators • Arrays • Strings • Structure and Union Types • File Processing • Pointers and dynamic memory allocation • Stacks, Queues, Binary Trees

  6. Texts • Problem Solving and Program Design in C, Hanly and Koffman, Addison-Wesley, 1996.

  7. History of Electronic Computers • First electronic computer built in late 1930’s by Atanasoff and Berry • First general purpose computer called ENIAC, 1946 • These computers used vacuum tubes. Later computers used integrated circuits, LSI, VLSI

  8. Categorization of Computers • Microcomputers • Workstations • Mainframes • Supercomputers • Minicomputers • Servers

  9. Computer Hardware • Main memory • Secondary memory • Central processing unit • Input devices • Keyboards • Mouses • Output devices • Monitors • Printers

  10. Memory • The memory of a computer is an ordered sequence of storage locations called memory cells • Each memory cell has a unique address • The data stored in a cell are called the contents of the cell • A cell may contain diverse types of data - numbers, characters, or program data

  11. Bytes and bits • A memory cell is a grouping of smaller units called bytes. • A byte is the amount of storage required to store a single character • A bit (binary digit) is the smallest unit a computer can deal with • A bit is either 0 or 1

  12. Storage and Retrieval of Information in Memory • To store a value in a memory cell, the computer sets each bit of the cell to 0 or 1, destroying the previous values • To retrieve a value from a memory cell, the computer copies the contents of the cell to another area

  13. Main memory • Random access memory (RAM) is volatile (data is lost when the computer is turned off). • Read only memory (ROM) is non-volatile and is often used to store the startup instructions of the computer • Cache memory is fast RAM

  14. Secondary Storage Devices • Disk drives are read-write random access devices with files organized in directories and subdirectories • Hard disks • Floppy disks • CD-ROM drives are (usually) read-only random access devices • Tape drives are read-write sequential access devices

  15. Central Processing Unit • Coordinates all computer operations • Performs arithmetic and logical operations on data • Stored programs are executed in a cycle of instruction fetch, instruction decode, data fetch, instruction execute, result store sequences

  16. Input/Output Devices • I/O devices allow us to enter data for a computation and observe the results of the computation • Keyboard • Mouse • Monitor • Printer

  17. Programming Languages • Machine languages are the native languages of the computer and are coded as strings of 0’s and 1’s • Assembly languages substitute symbolic names for strings of 0’s and 1’s • High-Level Language instructions correspond to sequences of assembly language instructions and are easier to read/write

  18. Relationship Between High-Level and Machine Languages • In order to be executed by a computer, a program written in a high-level language (source program) must be translated to machine language • The translator is called a compiler • The resulting program is called an object program

  19. Operating System • The software which controls the operation of a computer is called the operating system • Operating systems may have graphical interfaces (GUIs) command line interfaces (CLIs) or both

  20. Software Development Method • Specify the problem requirements • Analyze the problem • Design the algorithm to solve the problem • Implement the algorithm • Test and verify the completed algorithm • Maintain and update the program

  21. Case Study: Miles to Kilometers • Analyze the problem • Problem input: distance in miles • Problem output: distance in kilometers • Additional constraints on the solution?

  22. Design • Algorithm • Get the distance in miles • Convert the distance to kilometers • Display the distance in kilometers • Refine the algorithm • The distance in kilometers is 1.609 times the distance in miles
