Include double-quote (") in C-string [duplicate]

Question

I would like a to define a variable string in C that contains the following set of characters: a-zA-Z0-9'-_”.

Therefore I would do it like this:

char str[64] = "abcdefghijklmnopqrstuwxyzABCDEFGHIJKLMNOPQRSTUWXYZ0123456789'-_""

As you can see the problem is at the end with " character.

Question 1: How can I work around that?

Question 2: Is there a better way than my way to define a string like that?

PS: I didn't really know how to title my question, so if you got a better one, please edit it.

Answer 1

use the backslash: "\"" is a string containing "

like this:

char str[67] = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'-_\"";

added one for the implicit '\0' at the end (and put in the missing vV) - this could also be:

char str[] = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'-_\"";

and let the compiler count for you - then you can get the count with sizeof(str);

How does it add up to 67?

a-z 26
A-Z 26
0-9 10
'-_" 4
'\0' 1
    ---
    67

Answer 2

Use "\"" (backslash") for putting " in a string
