How to Input Non-Printable Characters to a C Program
Understanding Non-Printable Characters
When working with C programs, you may encounter situations where you need to input non-printable characters, such as newline, tab, or backspace. These characters are not visible on the screen but play a crucial role in programming. In this article, we will explore how to input non-printable characters to a C program.
Non-printable characters are used to control the flow of a program or to perform specific actions. For example, the newline character (\n) is used to move the cursor to the next line, while the tab character (\t) is used to insert a tab space. To input these characters, you need to use their ASCII values or escape sequences.
Inputting Non-Printable Characters in C
The C programming language provides several ways to input non-printable characters. One way is to use the ASCII value of the character. For example, the ASCII value of the newline character is 10, so you can use the code \x0A to represent it. Another way is to use escape sequences, such as \n for newline or \t for tab.
To input non-printable characters in a C program, you can use the scanf() function with the appropriate format specifier. For example, to input a newline character, you can use the code scanf("%c", &ch), where ch is a character variable. You can also use the getchar() function to read a single character from the input stream. By using these methods, you can easily input non-printable characters to a C program and perform various operations with them.
