Introduction

The MicrosoftÒ run-time library is a set of more than 550 ready-to-use functions and macros designed for use in C and C++ programs. The run-time library makes programming easier by providing

Fast and efficient routines to perform common programming tasks (such as string manipulation), sparing you the time and effort needed to write such routines

Reliable methods of performing operating-system functions (such as opening and closing files)

The run-time library is important because it provides basic functions not provided by the C and C++ languages themselves. These functions include input and output, memory allocation, process control, graphics, and many others.

This book describes the run-time library routines included with Microsoft C/C++ version 7.0. These comprise all of the routines included with earlier versions of Microsoft C, as well as many new routines.
