About Problem Solving Through Programming In C
This course is aimed at enabling the students to
- Formulate simple algorithms for arithmetic and logical problems
- Translate the algorithms to programs (in C language)
- Test and execute the programs and correct syntax and logical errors
- Implement conditional branching, iteration and recursion
- Decompose a problem into functions and synthesize a complete program using divide and conquer approach
- Use arrays, pointers and structures to formulate algorithms and programs
- Apply programming to solve matrix addition and multiplication problems and searching and sorting problems
- Apply programming to solve simple numerical method problems, namely rot finding of function, differentiation of function and simple integration
COURSE LAYOUT
- Week 1 : Introduction to Problem Solving through programs, Flowcharts/Pseudo codes, the compilation process, Syntax and Semantic errors, Variables and Data Types
- Week 2 : Arithmetic expressions, Relational Operations, Logical expressions; Introduction to Conditional Branching
- Week 3 : Conditional Branching and Iterative Loops
- Week 4 : Arranging things : Arrays
- Week 5 : 2-D arrays, Character Arrays and Strings
- Week 6 : Basic Algorithms including Numerical Algorithms
- Week 7 : Functions and Parameter Passing by Value
- Week 8 : Passing Arrays to Functions, Call by Reference

CRITERIA TO GET A CERTIFICATE
This course will have an unproctored programming exam also apart from the Proctored exam, please check announcement section for date and time. The programming exam will have a weightage of 25% towards the Final score.
Final score = Assignment score + Unproctored programming exam score + Proctored Exam score
- Assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
- ( All assignments in a particular week will be counted towards final scoring – quizzes and programming assignments).
- Unproctored programming exam score = 25% of the average scores obtained as part of Unproctored programming exam – out of 100
- Proctored Exam score =50% of the proctored certification exam score out of 100
YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF ASSIGNMENT SCORE >=10/25 AND UNPROCTORED PROGRAMMING EXAM SCORE >=10/25 AND PROCTORED EXAM SCORE >= 20/50.
If any one of the 3 criteria is not met, you will not be eligible for the certificate even if the Final score >= 40/100.
