发帖数: 524 | 1 Let's say I have a class A defined as follows. The vector v as a member of
the class should be initialized to have size = 10. The following code does
this job. However, I am wondering if it is possible to initialize v in the
initialization list, i.e., the same way that a is initialized?
class A{
int a;
vector v;
public:
A() : a(0) {
v = vector(10);
}
} | z****e

int a;
vector v;
public:
A() : a(0),v(vector(10)) {
cout<
}
};
or:
A::A() : a(0),v(10) {
cout<
} | t****t

(the {1, 2, 3} syntax) to initialize it.
