初学者请问：getline中使用Tab制表符在.size()里如何计算的？
Accelerated C++ 第一章的例子，想用getline抓取带有空格的姓名，然后发现，输入姓名时用了Tab的话，输出就不能对齐了
int main(){ string sname; getline(cin, sname); const string greeting = "Hello, " + sname + "!"; const string blank(greeting.size(), ' '); const string second = "* " + blank + " *"; const string first(second.size(), '*'); cout << first << endl; cout << second << endl; cout << "* " << greeting << " *" << endl; cout << second << endl; cout << first << endl; return 0;}
