C Print Only Printable Chars

What are Printable Characters?

When working with strings in C programming, it's not uncommon to encounter characters that are not printable, such as newline characters, tabs, or other non-ASCII characters. In some cases, you may want to print only the printable characters in a string, ignoring any non-printable characters. This can be useful for a variety of applications, including data processing, text analysis, and more.

Printable characters are those that can be displayed on a standard keyboard and are typically used to represent text. In C, printable characters include letters (both uppercase and lowercase), digits, punctuation marks, and whitespace characters (such as spaces, tabs, and newline characters). Non-printable characters, on the other hand, include control characters, escape sequences, and other special characters that are not typically displayed on a standard keyboard.

Example Code: Printing Only Printable Chars

What are Printable Characters? In C programming, printable characters are those that have an ASCII value between 32 (space) and 126 (tilde). This range includes all the letters, digits, punctuation marks, and whitespace characters that are commonly used in text. To print only printable characters, you can use a simple loop to iterate over the string and check each character's ASCII value. If the value falls within the printable range, you can print the character; otherwise, you can skip it.
