MISRA C:2012  Rule-4.1:  (Required)			Octal and hexadecimal escape sequences shall be terminated

Amplification:

An octal or hexadecimal escape sequence shall be terminated by either:

• The start of another escape sequence, or
• The end of the character constant or the end of a string literal.

Example Code:

#include "m3cmex.h"


extern int16_t rule_0401( void )
{
    const char *s1 = "\x41g";                           /*                */ /* Non-compliant */
    const char *s2 = "\x41" "g";                        /*                */ /* Compliant - terminated by end of literal */
    const char *s3 = "\x41\x67";                        /*                */ /* Compliant - terminated by another escape */
    uint16_t c1 = '\141t';                              /*      0284 3628 */ /* Non-compliant */
    uint16_t c2 = '\141\t';                             /*      0284 3628 */ /* Compliant - terminated by another escape */

    return 1;
}
