LEARNING OBJECTIVES: To introduce concepts of programming with a basic and widely used programming language C and introduction to scripting concepts in Linux operating system. The major objective of this course is to provide students with understanding of code organization and functional hierarchical decomposition with using complex data types. COURSE OUTCOMES: After completing the course, students shall be able toCO1. To understand the use of software and programming for problem solving. CO2. To understand modular programming approach in diversified problem in biological domains. CO3. To apply the concepts of input, output and control statements, functions, arrays, strings, structures, and file handlers to solve biological problems using C language CO4. To apply programming logic to solve Bioinformatics problems.
