Token are usually separated by white space which can be one or more

• Blank's

• Tabs

• Newline

• Form Feed

• Comments

1. Blank's :-

A blank space refers to the regular space character that you type using the space bar. It is represented by the character ' '. If you want to check whether a character is a space, you can use the ' ' character directly.

2. Tabs :-

The tab character (\t) is an escape sequence that represents a horizontal tab. When encountered in a string, it causes the cursor to move to the next horizontal tab stop.

3. New line :-

In C programming, you can create a new line by using the newline character \n within a string.

4. Form feed :-

In C programming, the form feed character (often represented as 'f') is an ASCII control character that serves as a page break. When encountered, it instructs the printer to eject the current page and continue printing at the top of another page.

5. Comments :-

comments are text ignored by complier comments are useful for documentation of your code useful programme

There are two types of comments

• Single line comments

• Multi line comments

  1. Single line comments :-

In C programming, a single-line comment starts with // and extends to the end of the line. These comments are completely ignored by the compiler during compilation.

2. Multi line comments :-

In C programming, you can use multi-line comments to add explanatory text that spans multiple lines. These comments are ignored by the compiler and are useful for documenting your code.
