是必须带:name(name),salary(salary)?

Question

Emp(string name" ",double.salary=0):name(name),salary(salary)

Answer 1

Emp(string name" ",double.salary=0):name(name),salary(salary)
完全等价于：
Emp(string Name" ",double Salary=0):
{
strcpy(name,Name);
salary = Salary;
}
前者就是后者简单的赋值语句的简写而已，两者等价。

Answer 2

不是必须
好好学语法吧， 先搞清楚这是个什么语法再说
