QA·C Help - 3627

	3627	Single-quote character in a string literal is not preceded by a backslash character.

Constants

This string literal includes a single-quote character (") - an apostrophe. An escape sequence representation may be preferred.

When a single-quote character is required in a character constant, it must be represented using an escape sequence (\'); but this isn't essential in a string literal.

Similarly, when a double-quote character is to be represented in a string literal, it must be represented using an escape sequence (\"); but this isn't necessary in a character constant.

Some coding standards recommend that, for consistency, all single-quotes and double-quotes should be coded using escape sequences whether they occur in character constants or string literals.

For example:


/*PRQA S 2017,3123,3211,3408,3602,3625 ++*/

char pca = '"';                                 /* Message 3626 */
char pcb = '\"';                                /*              */
char pcc = '\'';                                /*              */

const char * psa = "an apostrophe:     '";      /* Message 3627 */
const char * psb = "an apostrophe:    \'";      /*              */
const char * psc = "a quotation mark: \"";      /*              */
