C語言字串拷貝示例

在C語言中，如何拷貝字串？創建一個原始檔案：program_to_copy_string.c，參考以下實現代碼 -

#include <stdio.h>

int main() {
    char s1[] = "xuhuhu.com";       // String Given
    char s2[18];                   // Variable to hold value

    int length = 0;

    while (s1[length] != '\0') {
        s2[length] = s1[length];
        length++;
    }

    s2[length] = '\0';           // Terminate the string

    printf("Value in s1 = %s \n", s1);
    printf("Value in s2 = %s \n", s2);

    return 0;
}

執行上面示例代碼，得到以下結果 -

Value in s1 = xuhuhu.com
Value in s2 = xuhuhu.com
