C++ Standard Library

C/C++ Standard Library comes with various useful functions for use in your programs.
You “include” the appropriate interface header file into code so the compiler can check the syntax.
We will discuss various system calls related to the current time
Includes local time, GMT time, time formatting
Numerous mathematics-oriented functions in the math library, including sine, cosine, etc.
We also handle random numbers
Several functions for testing and converting characters
Several functions for manipulating C character array strings
Here are links to various items in the Standard Library: http://www.cplusplus.com/reference/clibrary/ http://www.cplusplus.com/reference/clibrary/ctime/ http://www.cplusplus.com/reference/clibrary/cmath/ http://www.cplusplus.com/reference/clibrary/cstdlib/ http://www.cplusplus.com/reference/clibrary/cstring/ http://www.cplusplus.com/reference/clibrary/cctype/
