Scope of this Manual

C++, like C, is a language that is heavily reliant on a rich set of library functions to provide the following:

• Portable operating-system interface (file and screen I/O)
  
  
• String and buffer manipulation
  
  
• Floating-point math transformations
  
  
• Other supporting functionality

For information about the run-time library functions, see the Run-Time Library Reference. For information on the Microsoft Foundation classes or the iostream classes, see the Class Library Reference or the iostream Class Library Reference, respectively.
