Today, a colleague asked me how to embed the DLL dynamic link library directly into the C # developed application. Program It is only an .exe file rather than a folder. I thought about this issue carefully. Publish the secret file to the user. In

First function: calculate the number of substrings in a string.Int strstr_cnt (const char * string, const char * substring ){Int I, J, K, Count = 0;For (I = 0; string [I]; I ++ ){For (j = I, K = 0; (string [J] = substring [k] & (j If (! Substring [k

There are two types of string streams in C ++, one is defined in sstream,Another type is defined in strstream.They basically implement the same thing. Strstream containsClass strstreambuf;Class istrstream;Class ostrstream;Class strstream;They are

Cast is used for type conversion. Cast commonly used in C ++ has the following types:1. static_cast: used to convert the Child class to the parent class in inheritance. For example, child * Ch = new child (); Father * Fa = static_cast (CH );2.
