Unit II: Variable and Data Types | BCA 2nd Semester C Programming Notes Pdf

A variable is a data name that may be used to store a data value. Unlike constants that remain unchanged during the execution of a program, a variable may take different values at different times during execution. A variable name can be chosen by the programmer in a meaningful way to reflect the program's function or nature.
