wcscmp

strcmp, wcscmp一样都是比较字符串的指针函数原型

int strcmp( const char*string1,const char*string2);

int wcscmp( const wchar_t*string1,const wchar_t*string2);

参数

string1,string2为以零值结尾的字符串所有版本的c运行库都支持

返回值

< 0

string1小于string2

0

string1相当string2

> 0

string1大于string2

wcscmp 比较宽字符

例子

/* STRCMP.C */

#include <string.h>

#include <stdio.h>

char string1[] = "The quick brown dog jumps over the lazyfox";

char string2[] = "The QUICK brown dog jumps over the lazyfox";

void main( void )

{

char tmp[20];

int result;

/* Case sensitive */

printf( "Comparestrings:

%s

%s

", 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("strcmp: String 1 is %s string 2

", tmp );

/* Case insensitive(could use equivalent _stricmp) */

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("_stricmp: String 1 is %s string 2

", tmp );

}

结果

Compare strings:

The quick brown dog jumpsover the lazy fox

The QUICK brown dog jumpsover the lazy fox

strcmp: String1 is greater than string 2

_stricmp: String 1 isequal to string 2
