You can use "string" class in C++ for string operations or you may use c style string functions as well. #include <string> String class in C++ provides all basic function to operate on strings. you may details descriptin at http://www.cplusplus.com/reference/string/string/
You do not need to program string manipulation as it is already part of the standard library. See std::string and std::wstring.
C++ already provides a string class in the C++ standard template library. #include<iostream> #include<string> int main() { using namespace std; string s {"Hello world!"}; cout << s << endl; }
The runtime library is a collection of routines that implements basic functionality of the platform. Routines such as I/O, memory control, startup, shutdown, common system functions, etc. are located in the runtime library.
std::string::substr();
In short you cannot, unless you provide a suitable alternative to the standard library yourself (in other words, reinvent the wheel). At the very least you will need to include the common runtime definitions (crtdefs.h) just to create a bare-bones program that does absolutely nothing, but you'll need to implement all the standard IO functions yourself. Even third-party replacements make extensive use of the standard library, so you're completely on your own here. The standard library exists so that you can draw upon a rich set of primitive but highly optimised, tried and tested functions which act as building blocks upon which you can create your own programs.

The C++ standard library contains all the pre-defined functions.
C++ built-in functions are those functions that are provided for you as part of the language itself, and includes all of the C standard library functions (all of which were inherited from C) and is expanded upon by the C++ standard template library. C++ implementors may provide additional functions that are platform-specific, however these are not considered built-in functions becuase C++ is a cross-platform language. These are best described as 3rd party functions. The functions you yourself write are known as user-defined functions.

Standard Template Library. The STL basically provides templates for common containers, such as lists and queues, as well as functions, iterators and algorithms.

Write your own C++ functions for the following problems:o Sort a book list in a library based on the disciplineo Print the sorted output on the console
This are the predefined functions in c, which are already write.Examples : printf(),scanf().
The plus operator between string constants allows string concatination: string a = "Hello, "; string b = "World!"; string c = a + b; The output of c would be: "Hello, World!".
Yes.
