    很简单的C代码，执行时会报错：Abort trap: 6

    void strcat2(char *s, char *t) {
    //s指向'\0'
    while(*s)
    s++;
    while(*s++ = *t++)
    ;
    }

    int main() {
    char s[] = " hello ";
    char t[] = " world ";
    strcat2(s, t);
    printf("%s\n", s);
    printf("%s\n", t);
    }
  • char
  • ++
  • while

    突然觉得喷神王ying的有篇文章还是多有道理的，代码的简洁不在于行数在于表意。
