Lucas theorem: N is written in P-ary A[n]a[n-1]a[n-2]...a, and M is written in P-b[n]b[n-1]b[n-2]...b, then C (n,m) and C (A[n],b[n]) *c (a[n-1],b[n-1]) *c ( A[n-2],b[-2]) *....*c (a,b) modulo p congruence.namely: Lucas (n,m,p) =c (n%p,m%
Introduction to String class functions in standard C + +Look, it's not CString.The reason to discard char* strings and select the String class in the C + + standard library is because he compares with the former, doesn't have to worry about enough

Continue writing some string operations today.String gives us a lot of ways, but every time we use it, it's going to be a bit of a hassle.Scenario 1:Get a std::string Full_path = "D:\program files\csdn", but I want to get the "D:\program Files\vagaa"
I believe that the use of MFC programming friends to CString this kind of impression should be very profound? Indeed, the CString class in MFC is really convenient and easy to use. But if you leave the MFC framework, are there any classes that are
