'character' : unrecognized character escape sequence
The character following a backslash (\) in a character or string constant is not recognized as a valid escape sequence. The backslash is ignored and not printed. The character following the backslash is printed.
To print a single backslash, specify a double backslash (\\). The following sample generates C4129:
void main() { char array1[] = "\/709"; // C4129 char array2[] = "\n709"; // try this }
