ASCII Values in C


The full form of ASCII is the American Standard Code for information interchange. It is a character encoding scheme used for electronics communication. Each character or a special character is represented by some ASCII code, and each ascii code occupies 7 bits in memory.

In C programming language, a character variable does not contain a character value itself rather the ascii value of the character variable. The ascii value represents the character variable in numbers, and each character variable is assigned with some number range from 0 to 127. For example, the ascii value of 'A' is 65.

In the above example, we assign 'A' to the character variable whose ascii value is 65, so 65 will be stored in the character variable rather than 'A'.

128 total character which is used mostly during program.
 
Total number of Character in ASCII table is 256 (0 to 255).
 
0 to 31(total 32 character ) is called as ASCII control characters
include 'Escape', 'Backspace' and 'Delete'.
 
32 to 127 character is called as ASCII printable characters
 
128 to 255 is called as The extended ASCII codes
