Preprogramming techniques
Pre programming techniques is a step-by-step description of program in a simple English language.
Preprogramming tools
- Algorithms
- Flowchart
What is Algorithm?
Algorithms is step-by -step procedure, which is used to solve complex problem. Or we can say algorithm is step by step solution of the problem.
What is Flowchart?
- a step by step procedure for solving a problem in symbolic form is called Flowchart.
- Flowchart solves the problem in symbolic form so it is easy to understand.
- It can be read from top to bottom and left to right
Dry run
- a dry run is a testing process where the effect of a possible faliure are intenionally trialed.
- A dry run is the process of a programmer manually working through their code to trace the value of variable.
- there is no software involved in this process.
- A dry run might also be used to check an algorithm during program design.
- Dry running a program involves the programmer working through a program on paper
