wcscmp

strcmp, wcscmp一樣都是比較字元串的指針函式原型

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

基本介紹

• 中文名：wcscmp
• 釋義：指針函式原型
• 性質：專業術語
• 來源：數學算法

參數

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

string1, string2 為以零值結尾的字元串所有版本的c運行庫都支持

返回值

< 0	string1 小於string2
0	string1與string2相等
> 0	string1 大於 string2; wcscmp 比較寬字元

函式代碼

/* 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:\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(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("\t_stricmp: String 1 is %s string 2\n", tmp );

}

輸出結果

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
