c /c ++庫strxfrm()將源字符串的字符轉換為當前語言環境,並將其放置在目標字符串中。對於該LC_COLLATE類別,該類別在locale.h中定義。 strxfrm()函數執行轉換的方式是,兩個字符串上的strcmp結果與兩個原始字符串上的strcoll結果相同。句法:
size_t strxfrm(char *str1, const char *str2, size_t num); parameters: str1:is the string which receives num characters of transformed string. str2:is the string which is to be transformed num :is the maximum number of characters which to be copied into str1.
例子:
Input:'geeksforgeeks' Output:13
// C program to demonstrate
// strxfrm()
#include <stdio.h>
#include <string.h>
int main()
{
char src[10], dest[10];
int len;
strcpy(src, "geeksforgeeks");
len = strxfrm(dest, src, 10);
printf("Length of string %s is:%d", dest, len);
return (0);
}
輸出:
Length of string geeksforgeeks is:13
範例2:
Input:'hello geeksforgeeks' Output:20 // in this example it count space also
// C program to demonstrate
// strxfrm()
#include <stdio.h>
#include <string.h>
int main()
{
char src[20], dest[200];
int len;
strcpy(src, " hello geeksforgeeks");
len = strxfrm(dest, src, 20);
printf("Length of string %s is:%d", dest, len);
return (0);
}
輸出:
Length of string hello geeksforgeeks is:20
範例3:
// C program to demonstrate
// strxfrm()
#include <iostream>
#include <string.h>
using namespace std;
int main()
{
char str2[30] = "Hello geeksforgeeks";
char str1[30];
cout << strxfrm(str1, str2, 4) << endl;
cout << str1 << endl;
cout << str2 << endl;
return 0;
}
輸出:
19 Hell Hello geeksforgeeks
