There is class having a constructor taking a single int argument (there is
no default constructor). Declare an array of 500 objects of that class.

是年轻的faculty，没有其他路子搞钱，只能死搞grant，7-9% payline of NIH，基本
没有太多机会。找个有钱的大lab，先干几年research track。等待时机反攻。。。。

is a loop necessary?
for(int i=0; i<500; i++) {
pClasses[i] = new MyClass(int);
}

array of 500 objects of that class.

I am a new learner of C++, can you elaborate a little bit? Thanks a lot!
why "pClasses[idx] = new MyClass(int);" works?
what is idx?

几年前我有考虑过这条路的。当时版上好多人都警告我这是一条career dead end.
如果你是在National lab里面当scientist 还行，在大老板手下当RAP不是一个特别好的
选择。

vector也算数组，就是不知道考官同意不同意这个观点，我觉得至少这个不是他想要的答案

It's all depending on your contract. Research track and tenure track shouldn
't have too much difference, but both follows institute's guideline. Some
institutes allow the transition from research track to tenure track, but not
vice versa. However, research track don't usually come with start funding
at the starting point, therefore it's pretty tough to kick the ball rolling
for a NIH funding. If everything works well, you may fund your project
through internal grant or some non-NIH grant. When you gets grant on your
hands, you can initiate a new process for a better contract with your
institute for either a promotion or go to somewhere else with the grant.
It's all about how to negotiate with your institute.

It is all about grants. I know someone who was a research faculty for 10
years, now he/she is fully tenured with 2 R01 and 1 R21 in 6 years. A
tenure track faculty has start up fund but usually has to have new and novel
idea to get grant (you usually can't do what your old boss is doing).
However, a research faculty can be very close to his/her P.I. project and
get R01 as long as he/she can show to the reviewers that the project is an
independent idea.
Both positions require external funding or goodbye to the position in 5-6
years (research faculties might have some extra time). As for institutional
funding, everyone is fighting for it. It could be harder than external
funding.

What about this answer?
class Array{
Array(int);
}
Array *a;
a = (Array *)malloc(sizeof(Array) * 500);

对了一半，只分配了内存块，如果class不是POD(有vptr)或者含有动态内存指针, 这个array还是没法用

我说的是，如果刚做完postdoc，有这种机会，好像比进tenure track要好些。如果能
找到不需要你自己争取funding的位置（花大老板的钱），只是埋头做研究，发CNS，呵

500 个是同一个 class吗？

very nice solution~
//my solution:
//create: using placement new
A* pa = static_cast (malloc(sizeof(A)*500));
A* pn = pa;
for (int i = 0; i < 500; ++i)
{
pn = new(pn) A(i);
++pn;
}
//destroy: explicit invoke destructor
pn =pa;
for (int i = 0; i < 500; ++i)pn++->~A();
free(pa);

interesting, why do you think it doesn't work for vptr? vptr is nothing just
a pointer, kind like:
class A
{
void* pVtbl;
int value;
public:
A(int v):value(v) {};
};
then:
A temp(123);
A* pBuffer = (A*)malloc(sizeof(A)*500);
for(int i=0;i<500;++i)
{
mempcy(pBuffer++, &temp, sizeof(A));
}
这个问题应该是让你模仿vector去实现类似功能（不是直接让你用vector）

这个array还是没法用
