1.2

Write code to reverse a C-Style String. (C-String means that “abcd” is represented as five characters, including the null character.)

void reverse(char* str){if(str==NULL)    return;int i=0,j=strlen(str)-1;while(i<j){int tmp=str[i];str[i]=str[j];str[j]=tmp;//forget i++,j-- when writing on paperi++;j--;}}

在纸上，看似简单的代码还是总出问题：我忘记了i++，j--，将纸上的程序输入到计算机中时导致死循环
