ICPTP L2: Program Design

What is a Computer Program?

• A set of precise steps that describe exactly the tasks to be performed and the order in which they are to be carried out

• A set of detailed, unambiguous and ordered instructions

• A series of instructions to carry out a particular task written in a language that the computer understands

• Structured English used to represent algorithms

What does a Programmer do?

• Gather requirements

• Prepares instructions of a computer program

• Runs the instructions on the computers

• Tests to see if it's working properly

What is an algorithm?

• A set of precise steps that describe exactly the tasks to be performed and the order in which they are to be carried out

• A series of instructions to carry out a particular task written in a language that the computer understands

• A set of detailed, unambiguous and ordered instructions

• Structured English used to represent algorithms

What is pseudo code?

• A set of detailed, unambiguous and ordered instructions

• A series of instructions to carry out a particular task written in a language that the computer understands

• Structured English used to represent algorithms

• A set of precise steps that describe exactly the tasks to be performed and the order in which they are to be carried out

What is the purpose of desk checking the algorithm?

• To gather requirements

• To test the program on the computer

• To write up the program documentation

• To identify major logic errors early

What is Step Two in Program Development?

• Define the problem

• Outline Solution (Design/Plan Solution)

• Test Algorithm for correctness

• Develop the outline into an algorithm

What is Step Three in Program Development?

• Define the problem

• Outline Solution (Design/Plan Solution)

• Develop the outline into an algorithm

• Test Algorithm for correctness

What is Step Four in Program Development?

• Develop the outline into an algorithm

• Outline Solution (Design/Plan Solution)

• Define the problem

• Test Algorithm for correctness

What is Step Five in Program Development?

• Develop the outline into an algorithm

• Outline Solution (Design/Plan Solution)

• Code the algorithm into a specific programming language

• Define the problem

What is Step Six in Program Development?

• Document and maintain the program

• Run the program on the computer

• Outline Solution (Design/Plan Solution)

• Define the problem
