3. Variables, Data Types, and Arithmetic Expressions

The C language allows data types other than just integers to be stored in variables as well, provided the proper declaration for the variable is made before it is used in the program. Variables can be used to store floating-point numbers, characters, and even pointers to locations inside the computer’s memory.
