The char data type is used to store the characters. The characters stored in a variable of char data type have a value equivalent to its integer code. These codes are often called American Standard Code For Information Interchange or ASCII codes. The ASCII code for upper case characters A to Z starts from 65 to 90 and for lower case characters a to z, it starts from 97 to 122.
The general size of a character is 1 byte. However, just like the integers the size of a char can vary according to the data type modifiers. Since all characters and symbols can be represented in their numerical ASCII value, the char type is often considered as an int type.
