看看我的示例代码

struct A
{
   int member;
};

int main()
{
   int A; //Line 1
   A b;   //Line 2 
   b.member = int(); //Line 3
}

错误是

prog.cpp: In function ‘int main()’:
prog.cpp:9: error: expected `;' before ‘b’
prog.cpp:9: warning: statement has no effect
prog.cpp:10: error: ‘b’ was not declared in this scope

如何在第二行访问结构A？为什么我还是得到错误？
