C Special Characters

Strings - Special Characters

Because strings must be written within quotes, C will misunderstand this string, and generate an error:

char txt[] = "We are the so-called "Vikings" from the north.";

The solution to avoid this problem, is to use the backslash escape character.

The backslash () escape character turns special characters into string characters:

Escape character	Result	Description
'	'	Single quote
"	"	Double quote
		Backslash

The sequence " inserts a double quote in a string:

Example

char txt[] = "We are the so-called "Vikings" from the north.";

The sequence ' inserts a single quote in a string:

Example

char txt[] = "It's alright.";

The sequence inserts a single backslash in a string:

Example

char txt[] = "The character is called backslash.";

Other popular escape characters in C are:

Escape Character	Result	Try it
n	New Line
t	Tab
�	Null
