Another way to continue a string is to have two or more consecutive strings. Adjacent string literals will be concatenated to produce a single string. For example:
"hello " "there" /* is equivalent to "hello there" */
"hello" "there" /* is equivalent to "hellothere" */Characters in concatenated strings remain distinct. For example, the strings "\xab" and "3" are concatenated to form "\xab3". However, the characters \xab and 3 remain distinct and are not merged to form the hexadecimal character \xab3 .
The concatenation of a wide string literal and narrow string literal is not supported in ILE C/C++. If a wide string literal and a narrow string literal are adjacent, as in the following:
"hello " L"there" the compiler will issue an error message.
Following any concatenation, '\0' of type char is appended at the end of each string. For a wide string literal, '\0' of type wchar_t is appended. C++ programs find the end of a string by scanning for this value. For example:
char *first = "Hello "; /* stored as "Hello \0" */
char *second = "there"; /* stored as "there\0" */
char *third = "Hello " "there"; /* stored as "Hello there\0" */
