ASCII Value

ASCII stands for American Standard Code of Information Interchange. There are 256 (0 to 255) distinct characters and each character has its own value known as ASCII value. With the help of ASCII value characters can be easily converted into binary code which is understandable by c compiler.

Character type	Range	No. of characters	ASCII value
Capital Letters	A to Z	26	65 to 90
Small Letters	a to z	26	97 to 122
Digits	0 to 9	10	48 to 57
Special Symbols		66	0-47, 58-64, 91-96, 123-127
Graphics Character		128	128 to 256
Total		256
