1. Acknowledgement.
I would like to express my sincere gratitude to Achyut Shah Thakuri for his invaluable
guidance and support throughout this C programming lab. His insightful explanations
and timely feedback were instrumental in my understanding of the core concepts of C
programming, such as variables, data types, operators, control flow statements, and
functions. His patience and encouragement motivated me to persevere through
challenges and strive for excellence.
I am particularly grateful for his assistance in troubleshooting errors and providing
alternative approaches to problem-solving. I got to learn a lot from his expertise in C
programming, especially in the area of input and output operations. By sharing his
knowledge and experience, he helped me to develop a deeper understanding of the
underlying principles and best practices.
2. Objective
The main objectives of the lab work are as follows:
1. To understand the anatomy of a C program.
2. To design a program with algorithms and flowchart.
3. To understand preprocessor directive and header files.
4. To get familiar with different data types.
5. To write a first C program.
6. To understand the compilation process.
7. To apply arithmetic and logical operators.
3. Theoretical Background
4. Work Done
5. Conclusion
Through this C programming lab, I delved into the fundamental input and output functions,
scanf and printf. I gained practical experience in using these functions to effectively
interact with the user and display formatted output. I learned how to format input and
output, handle different data types, and control the precision of numerical values. By
working on various exercises, I developed a strong understanding of the syntax and usage
of these functions.
I also gained insights into error handling techniques and best practices for input and output
operations. For instance, I learned how to validate user input to ensure it is within expected
ranges and formats. Additionally, I explored techniques to handle potential errors, such as
invalid input or file I/O failures. By implementing these error handling strategies, I can
write more robust and user-friendly C programs.
