ASCII – American Standard Code For Information Interchange.
- C supports only the characters that were given in the below ASCII table because C follows the ASCII character set. The remaining characters are treated as invalid.
- In C, 8 bits are used to represent a character. i.e. 0 – 255.
- But as of now, only 128 symbols were being used, and the remaining are reserved for future use or custom use.
- The above 8 bits of info represent the decimal value 64 i.e ‘@’ symbol in the ASCII table.
Please learn the below conversions :
- Decimal –> Binary, Octal, Hexadecimal.
- Binary –> Dec, Oct, Hex
- Hex –> Bin, Dec, Oct
- Oct –> Bin, Dec, Hex
NOTE: No need to write a C program for the above. Just learn the mathematical procedures of these conversions.
