The document discusses computer programming, which is the process of developing instructions to enable a computer to perform tasks. It involves writing, testing, and maintaining source code. Key aspects include knowledge of programming languages, problem definition and analysis, algorithm design, coding, testing and debugging. Flowcharts use symbols to represent the logical steps of a program and are a type of algorithm.
Introduction to programming (week 1)
- 2. The process of developing and implementing various sets of instructions to enable a computer to do a certain task. These instructions are considered computer programs and help the computer to operate smoothly.
- 3. It is also the process of writing, testing and maintaining the source code of computer programs
- 4. Knowledge and mastery of the programming language. Logic formulation
- 5. Is an artificial language that can be used to control the behavior of a machine, particularly a computer.
- 6. Problem definition Problem Analysis Algorithm design Coding Testing and debugging
- 8. Use of symbols and phrases to designate the logic of how a problem is solved. A combination representing the logical sequence in which a combination of steps or operations to be performed. It is a blueprint of the program.
- 9. Terminal (Start/Begin) Used to signify the beginning and end of flowchart
- 10. Preparation or Initialization (Sum=0, A=1) Used to select initial conditions
- 11. Input / Output (Read A or Print A) Shows input and output
- 12. Processing (Sum=A+B) Performs any calculations that are to be done
- 13. Decision (If A>B) Signifies any decisions that are to be done.
- 14. Flowlines – signifies the process that is to be aexecuted next.
- 16. Is a finite set of instructions that specify a sequence of operations to be carried out in order to solve a specific problem.
- 17. Draw a flowchart that will compute and display the sum and product of two numbers. Write its equivalent algorithm.
- 18. Draw a flowchart that will compute and display the area of a rectangle using the formula: Area =Length X width Start L=0 W=0 Area=0 Area=L *W Display Area End Read L, W
- 19. Draw a flowchart that will compute and display the area of a rectangle using the formula: Area =Length X width, if the Area is greater than 5, display the word Hello and if not display Hi Start L=0 W=0 Area=0 Area >5 Display Area End Read L, W Area=L *W Display Area
