Introduction to Program Analysis

• Programming is the software concept where it is the playback of a computer job. A computer person should be perfect in programming. The results of any computer job, printout, layout, results, and data processing all these tasks basically depend upon the programming technique and accuracy of programming. Program development is not so simple; it requires a number of systematic working steps to make it easy, simple, and perfect.
• Program development is a skill; it requires logic. Any problem that is to be computerized must be properly analyzed and organized. A program should always be planned because a computer is very precious, and one can't afford a computer by experimenting on methods of problem-solving.

Program analysis should be able to break down the problem into step-by-step procedures. It should ensure steps are within the computer's capabilities.

For example:
Add 2 numbers and display the result

1. Take 2 numbers, suppose a and b, as input.
2. Add 2 numbers.
3. Store the result and increment.
4. Display the value of c. 

For analysis of program there are various methods Those methods are as follows: 

1. Algorithm    : A diagram that shows the steps of a program using symbols and arrows.
2. Flowchart    : A step-by-step written procedure to solve a specific problem
3. Pseudocode : A plain language version of a program’s logic written like code but not in any specific programming language.
