NPTEL Problem solving through Programming In C Week 11 All Programming Assignment Solutions | Swayam 2023. With the growth of Information and Communication Technology, there is a need to develop large and complex software.
ABOUT THE COURSE:
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
