while(*p++=*p2++!='\0');与while(（*p++=*p2++）!='\0');//有什么区别?

C/C++ code

#include <iostream>using namespace std;int main() {     char array[5]="abcd";    char array2[5]="efgh";    char* p =array;    char* p2 =array2;    while((*p++=*p2++)!='\0');        if((*p)=='\0')//为什么不等于'\0'?            cout<<"\0"<<endl;}

C/C++ code

while(*p++=*p2++!='\0');与while(（*p++=*p2++）!='\0');//有什么区别//!=优先级高于=优先级，所以while(*p++=*p2++!='\0');相当于while(*p++=(*p2++!='\0'));
