[求助]求一个程序~~谢谢

づ嗳嘚亽鈊↑

例如：
Welcome to China!

反过来输出：
China to Welcome!

要求：必须处理字符串在初始的储存string里

下面是例子
For example:
{
string a;
getline(cin,a); //if you input the string”Welcome to China!”
//your process
//………
cout<<a; //then the output is “China to Welcome!”
}

半个灵魂

For example:
{

string a;
getline(cin, a); //if you input the string”Welcome to China!”

//your process
string::size_type pos = a.size()-1, pre_pos = pos;
int size =a.size();
while (pos=a.rfind(' ', pos))
{
a.append(a,pos, pre_pos);
pre_pos=--pos;
}
pos = a.find(' ', 0);
a.append(a, 0, pos-1);
a.erase(a.begin(), a.begin()+size+1);

cout<<a;//then the output is “China to Welcome!”
}
