The C language function library is a comprehensive collection of C standard library, IO functions, character processing functions, string functions, mathematical functions, time and date functions, and other common functions, which includes hundreds of commonly used C language functions. The "C语言函数库详解.doc" document provides a detailed introduction and explanation of the function prototypes, detailed functions, and usage examples of commonly used function libraries. The commonly used standard header files in C language include: 1. <assert.h>: diagnostics 2. <ctype.h>: character classification testing 3. <errno.h>: error handling 4. <limits.h>: integer constants 5. <locale.h>: locale environment 6. <math.h>: mathematical functions 7. <setjmp.h>: non-local jumps 8. <signal.h>: signals 9. <stdarg.h>: variable argument lists 10. <stddef.h>: common definitions 11. <stdio.h>: input and output 12. <stdlib.h>: utility functions 13. <time.h>: date and time functions The "C语言函数库详解.doc" document is organized into chapters, with the first chapter focusing on the C standard library. It provides detailed explanations and examples of the following: - <assert.h>: diagnostics - <ctype.h>: character classification testing This document serves as a valuable resource for C language programmers, offering in-depth explanations and examples of the various functions available in the C language function library. It is an essential guide for anyone looking to understand and utilize the power of C language functions in their programming projects.
