本文介绍了使用 C 语言中的 `strcmp` 和 `_stricmp` 函数进行字符串比较的方法，并通过实例展示了如何在不同场景下应用这些函数。此外，文章还提供了一个简单的 C 程序来计算字符串大小，帮助理解字符串操作的基础知识。

The quick brown fox jumps over the lazy dog.

一只敏捷的棕色狐狸跳到了一只懒狗身上。

据说该句是包含所有26个字母的最短的句子。

1句9词26字-----------微软MSDN中常用来做各种字符串比较操作的例子。

MSDN2001

Example

/* STRCMP.C */

#include < string.h>
#include <stdio.h>

char string1[] = " The quick brown dog jumps over the lazy fox ";
char string2[] = " The QUICK brown dog jumps over the lazy fox ";

void main( void )
{
     char tmp[ 20];
     int result;
     /* Case sensitive */
    printf( " Compare strings:\n\t%s\n\t%s\n\n ", string1, string2 );
    result = strcmp( string1, string2 );
     if( result > 0 )
        strcpy( tmp, " greater than " );
     else if( result < 0 )
        strcpy( tmp, " less than " );
     else
        strcpy( tmp, " equal to " );
    printf( " \tstrcmp:   String 1 is %s string 2\n ", tmp );
     /* Case insensitive */
    result = _stricmp( string1, string2 );
     if( result > 0 )
        strcpy( tmp, " greater than " );
     else if( result < 0 )
        strcpy( tmp, " less than " );
     else
        strcpy( tmp, " equal to " );
    printf( " \t_stricmp:  String 1 is %s string 2\n ", tmp );
}

Output

Compare strings:

The quick brown dog jumps over the lazy fox

The QUICK brown dog jumps over the lazy fox

strcmp: String 1 is greater than string 2

_stricmp: String 1 is equal to string 2

// demo.cpp

#include<iostream>
using namespace std;

int main()
{
                 // 01234567890123456789012345678901234567890123==45
     char slang[]= " The quick brown fox jumps over the lazy dog. ";

    cout<< " sizeof(slang)== "<< sizeof(slang)<<endl;

    cin. get();

     return 0;
}
