In the following code, I am creating an array of ASCII code for non-printing characters and validating each character through the isprint library function in a “ for loop“. The isprint is a library function that returns a non-zero value if the argument is a printable character. The answer to your question is that I will use the isprint function for each character. Now you are thinking about how I will validate? Now let’s see a C program to validate the above-mentioned non-printable characters. The following table contains the non-printable characters with their ASCII value in decimal and hex format. The non-printing characters are characters for content designing in word processors, which are not displayed at printing.

Word refers to these special characters as non-printing characters. In addition, Word uses several special characters for its own purposes, such as characters to indicate the end of a line or a paragraph. This blog post explains the non printable characters with their ASCII (American Standard Code for Information Interchange) value in decimal and hex format. Besides the normal content of your documents in Word, there are also characters that don’t normally display on the screen.
