MISRA.STRINGS.CONCAT

Narrow and wide string literals concatenated.

MISRA-C++ Rule 2-13-5 (required): Narrow and wide string literals shall not be concatenated.

[Undefined 2.13.4(3)]

Rationale

Concatenation of wide and narrow string literals leads to undefined behaviour.

Example

char_t n_array[]  = "Hello" "World";   // Compliant
wchar_t w_array[] = L"Hello" L"World"; // Compliant
wchar_t mixed[]   = "Hello" L"World";  // Non-compliant
