INSTRUCTIONS TO STUDENTS FOR PREPARING
PROGRAMMING IN C LAB REPORT

This Lab Manual is prepared to help the students with their practical understanding and development of programming skills, and how to make practical files/ report.
Students have to submit Lab Exercise report, and can be collected back after the instructor/course coordinator after it has been checked and signed.

At the end of the session, students should compile all the Lab Exercise reports into a single report and submit during the end session.

The lab report to be submitted during the end session should include at least the following topics: –
1. Top Cover page – Sample page given below.
2. Index – Sample page given below
3. Each experiment should include:
– Title of the program
– Algorithm (optional):

It is a method of representing the step by step process or solution for solving a problem. Each step is called an instruction and written in sequence.

Characteristics of an algorithm are:

Finiteness:- It terminates with finite number of steps.
Definiteness:- Each step of algorithm is exactly defined.
Effectiveness:- All the operations used in the algorithm can be performed exactly in a fixed duration of time.
Input:- An algorithm must have an input before the execution of program begins.
Output:- An algorithm has one or more outputs after the execution of the program.

– Flowchart (optional): Design on Blank Sheet at Left side part of file
– Source Coding
– Output: Write Blank Sheet at Left side part of file

Note: The lab exercises may not be completed in a single specific lab. Students are encouraged to complete the programming questions given in the exercise prior to come to the lab hour and do the lab for the given programs.
