|
programming language
|
a special language used to write computer instructions. Include key words, programmer-defined symbols, operators, puctuation, and syntax.
|
|
|
programming process
|
analyze requirements, design the solution (flowchart & pseudocode), validate the design, implement the design (code), test and debug the solution (compile/run), document the program
|
|
|
Analyze the requirements
|
verify the requirements, evaluate the problem to determine if it is solveable with a program, list required input and output data, determine whether the input data is avaliable for testing
|
|
|
Design the Solution
|
Develop a logical method to illustrate the sequence of steps. Flowcharts, control structures, pseudocode
|
|
|
Control Structures
|
allow the programmer to specify the code that will execute only if a condition is met
|
|
|
Storyboards
|
sketches of the user interface
|
|
|
User Interface
|
what the user actually sees
|
|
|
pseudocode
|
English representation of how the program code should be written
|
|
|
Validate the design
|
user verifies that the requirements are met and the program solves the problem put forth
|
|
|
Implement the design
|
write the code, create the user interface, and include comments in the code that explaint the code's purpose. Also do unit testing.
|
|
|
Unit Testing
|
testing the code as it is written
|
|
|
Test the solution
|
Test boundary values, use sample input data, document problems
|
|
|
Document the Solution
|
