Question
![Assume `scores` is a vector that contains these integers:
100, 78, 97, 65, 100, 88, 99, 100, 100, 86
Then the following code executes:
```cpp
for(int x = 1; x <= 4; x++)
scores.pop_back();
scores.resize(8);
if(! scores.empty())
scores.push_back(99);
```
**What does the vector contain now?**
