Full Form of CHAR
What is CHAR?
CHAR, short for Character, is a fundamental data type used in programming languages such as C, C++, Java, Python, and SQL to store a single character value, including letters, digits, punctuation marks, and special symbols. In most systems, it occupies one byte of memory and is mapped to ASCII or Unicode values for representation. In India, CHAR is an essential topic taught in computer science and information technology courses across engineering colleges, polytechnics, BCA and MCA programs, and professional certifications. Students preparing for competitive exams like GATE Computer Science, UGC NET, NIELIT O and A level, SSC, and various state technical recruitment tests frequently answer questions about character data types, their memory allocation, ASCII values, and the difference between CHAR and VARCHAR. This data type forms the building block for string manipulation, file handling, and database design, making it critical knowledge for software developers working in India's expanding IT and software services industry.
