Cstring -- left, right, find, reversefind

Cstring: Left (intNcount)

-- Returns the ncount character string before the string

Example:

Cstring STR (_ T ("Shop, Workshop "));

STR = Str. Left (4 );

Result: Str = "Shop ";

 

Cstring: Right (INT ncount)

-- Returns the string of ncount characters after the string

Example:

Cstring STR (_ T ("Shop, Workshop "));

STR = Str. Right (2 );

Result: Str = "Workshop ";

 

Cstring: Find (_ T (","))

Returns the index value of "," in the string.

Example:

Cstring STR (_ T ("Shop, Workshop "));

Int idex = Str. Find (_ T (","));

At this time: idex = 4;

 

Zong: to obtain "," content on the right

STR = Str. Right (Str. getlength ()-1-str.find (_ T (",")));

Where:

Str. getlength () = 7;

-1 exclude ","

-Str. Find (_ T (",") exclude all words before ","

 

Cstring: reversefind

Int reversefind (tchar ch) const;

Return Value:

Returns the index of the last character that matches the required character in the cstring object. If the required character is not found,-1 is returned.

Parameter: the string to be searched.

Note:

This member function searches for the last character that matches a substring in this cstring object. This function is similar to the runtime function strrchr.

Example: // cstring: reversefind example:

Cstring S ("abcabc ");

Assert (S. reversefind ('B') = 4 );
