What's the C escape sequence for blanks?

Question

I'm writing a program to count blanks, tabs, and newlines. I remember what the escape sequence for tabs and newlines are, but what about blanks? \b? Or is that backspace?

Answer 1

\b is backspace (ASCII 0x8). You don't need an escape for regular space (ASCII 0x20). You can just use ' '.

Answer 2

You mean "blanks" like in "a b"? That's a space: ' '.

Here's a list of escape sequences for reference.

Answer 3

Hi,

'\b' is backspace, and you don't really need an escape sequence for blanks as ' ' will do just fine.

Answer 4

If you want to check if a character is whitespace, you can use the isspace() function from <ctype.h>. In the default C locale, it checks for space, tab, form feed, newline, carriage return and vertical tab.
