Answer the following statements true (T) or false (F)

Question

1. A local class and a nested class are the same thing.
2. If v is a vector and i is an int variable, then in the following the value of i can be any nonnegative int value:
v[i] = i;
3. It is valid to initialize member variables in a class on the same line in which the variable is declared. For example, the following sets xx to 1000:
```
class A
{
public:
A(){}
private:
int xx = 1000;
};
```
4. If we use an out of range index with a vector, there be an error message from the compiler.

Answer 1

1. False
A local class has its definition in a block, whereas a nested class has its definition within another class.
2. False
3. True.
However, this feature is only available in C++11 or higher.
4. False.
The Standard Library vector was designed for speed, not safety. There is no range checking done for indexing. As we shall see, there is a range checked member function for the string and vector.
