用C语言编码实现:用指针实现：将字符串" C language programming "拼接到字符串" Our favorite is "的后面。

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

int main() {
    char str1[50] = "Our favorite is ";
    char str2[] = "C language programming";
    char *ptr1 = str1 + strlen(str1);
    char *ptr2 = str2;

    while (*ptr2 != '\0') {
        *ptr1++ = *ptr2++;
    }

    *ptr1 = '\0';

    printf("%s\n", str1);

    return 0;
}

输出结果：

Our favorite is C language programming
