Which is better vector or array list?
It depends... If you want a speedy processing go for array list If you want thread safety go for a vector
Is it the most efficient approach to access elements with the vector data structure?
Yes. A vector is a variable-length array but constant-time random-access is guaranteed regardless of an array's length.
How can you create array of an object in java?
Array's can hold only primitive data types. if you want a collection of objects you must use an ArrayList or a Vector.
What would happen if you put too few elements in an array when you initialize it?
If the array does not have an initial size parameter, the array would be the size of the initialization vector, so you would not be able to store any data beyond the end of those elements without crashing your program or causing memory bugs. If there is a specified array size and the initialization vector is smaller than that size, then all remaining elements will be set to the value 0; it is not an error to not specify all elements in the initialization vector.
What is the difference between vectors and arrays?
The abstraction are the same. However, the array may be of any objects, while a vector, in narrowed definition, each element is a scalar value (e.g, int, float, double, etc), to fulfill the abs(vector) = aScalarValue property of a vector. An array with the same data type would look exactly the same. But an array of Persons will be difficult to be a vector!
What is Bit And Bit vector in VHDL programming?
These are predefined words in VHDL standards. Bit indicates that the data type is a bit i. e. 0 or 1. A bit_vector is an array of bits. example: a: in bit; b: in bit_vector(1 downto 0);
What do string and vector and array all inherit from that has the size method so you can take it as an argument?
string, vector and array do not have a common base class. Overload your function to accept either a string, a vector or an array.

Main difference between Array List and Vector in Java?
List is not sync'd as a vector is.
Difference between vector and array list?
Vectors are thread safe but array lists are not. Hence array lists are faster than Vectors.
Is it the most efficient approach to access elements with the vector data structure?
Yes. A vector is a variable-length array but constant-time random-access is guaranteed regardless of an array's length.
Why is an array called a derived data type?
An array is not a derived data type at all. In order to be derived there has to be a base class and an array has no base class. Here is the basic declaration of the std::array template class from the <array> header file: template<class _Ty, size_t _Size> class array { // fixed size array of values // ... }; A vector, on the other hand, is derived (from the <vector> header file): template<class _Ty, class _Alloc = allocator<_Ty>> class vector : public _Vector_alloc<!is_empty<_Alloc>::value, _Vec_base_types<_Ty, _Alloc>> { // varying size array of values // ... };
What are numbers lined up horizontally called?
A horizontal array or a row vector.
What is the Difference between array and vector processors?
Vector processor and Array processor are just the same thing, its a CPU design where instruction are set includes operations that can perform mathematical operations on multiple data elements simultaneously.
What is VHDL calculators?
A virtual calculator can be implemented using VHDL. We call it VHDL calculator.
