C Data Types 2 Questions and Answers
C Data Types questions with answers help learners understand how data is stored, manipulated, and used in C programming. Data types form the foundation of C as they define the type of data a variable can hold, such as int, float, char, or double. Mastering C data types is essential for students preparing for placement exams or programming interviews at companies like TCS, Infosys, and Wipro. This topic often features in C programming MCQs and technical test questions that evaluate understanding of memory allocation, data precision, and type conversions. Practice these programming questions and answers to strengthen your core knowledge and prepare for real-world coding challenges.
