在C语言中的布尔数组谜题

解决布尔数组谜题的程序

#include <iostream>
using namespace std;
void makeZero(int a[2]) {
   a[ a[1] ] = a[ !a[1] ];
}
int main() {
   int a[] = {1, 0};
   makeZero(a);
   cout<<"arr[0] = "<<a[0]<<endl;
   cout<<"arr[1] = "<<a[1];
   return 0;
}

输出

arr[0] = 0
arr[1] = 0
You can use other ways too. Like this one which does not require the negation operation.
a[ a[1] ] = a[ a[0] ]
