Concatenation of stringsString strings are immutable strings, but they can also be spliced, just to create a new object. String string concatenation can use the "+" operator or the concat (string str) method of String. The advantage of the "+" operator is that you can concatenate any type of data stitching into a string, whereas the Concat method can only stitch strings of string type.Examples are as follows:1String S1 = "Hello";2 //Connect using the + operator3String s2 = s1 + ""; 4String s3 =
self () {$local _info = Parse_url (get_option (' SiteURL '));$local _host = $local _info[' host '];Check Selfif (Preg_match (/^http:\/\/\w+\.)? ($local _host)/", $_server[' Http_referer '])!= 0) return true;}

2. You can also connect a string object and a char array in this way.
For example:
Copy Code code as follows:
String s1= "Hello";
Char s2[]= "World";
cout
However, you cannot connect two char arrays or character literals in this way.
For example:
Copy Code code as follows:
String s1= "Hello";
String s2= "World";
String s3=s1+ "world";/right, you can connect a string object and a string literal
String s4= "Hello" + "world";//error, can

, and the compiler will be S3 memory.
void Main ()
{
S1 mine1;//OK, S1 is a type
S2 mine2;//ok,s2 is a type
S3 mine3;//Ok,s3 is not a type
S1.data = 5;//ERRORS1 is a type
S2.data = 5;//ERRORS2 is a type
S3.data = 5;//OKS3 is a variable
}
In addition, there are several ways to define the variable that defines the structure itself in the structure.
struct S6 {
s6* ptr;
};
This notation can only be used in C + +
typedef struct {
