The \OOO escape sequence in C is used to represent a character by its octal (base 8) ASCII value.
Here's an example of a C program that uses the \OOO escape sequence to print the character corresponding to octal value 012:
When the program is run, it will output "Character with octal value 012: " followed by a newline character, because octal value 012 represents a newline character in ASCII.
The \OOO escape sequence can be used to represent any character whose ASCII value can be represented in octal. The octal value must be between 0 and 777.
It is important to note that the octal representation of a character is not standardized across all platforms and may produce different results on different systems.
It is recommended to use the standard escape sequences or the \xHH hexadecimal escape sequence instead of the octal representation for portability.
You can also directly use the ASCII value of a character in the program like '\x0a' for newline character.
