Lab Works
This is the first "programming" course in B.Sc.CSIT. It builds the foundation on how to write a program using any high level language. Hence, this course requires a lot of programming practice so that students will be able to develop good logic building and program developing capability which is essential throughout the B.Sc.CSIT course and thereafter. 20% of the total marks is assigned from the practical. Some important contents that should be included in lab exercises are as follows:
Unit 1: (2 Hrs)
Create, compile, debug, run and test simple C programs
Unit 2,3,4: (5 Hrs)
Using different data types available in C, perform arithmetic operations in C, perform formatted input/output operations, perform character input/output operations.
Using relational operator, logical operator, assignment operator, ternary operator, and other operators. Evaluation of Expression to check operator precedence and associativity.
