谁能帮忙解释一下这个为什么无法运行。
#include <iostream>using namespace std;
int main()
{
int a, b, c;
cout << "please enter a,b,c" << endl;
cin >> a >> b >> c;
cout << "the biggest is ";
int mid;
{if (a > b)
mid = a;
{
if (mid > c)
cout << mid;
else
cout << c;
}
if (b > a)
mid = b;
{
if (mid > c)
cout << mid;
else cout << c;
}
}
system("pause");
return 0;
}
