A)
The Standard Template Library (STL) includes the collection of data types and
- A special data type called vector is offered by STL which is useful for standard arrays.
A vector stores the elements or values in sequence order and the values are stored in continuous memory locations.
- The subscript operator “[]” in the vector helps to read the content of each element.
- If there is a need of vector to be used in the programs, then the following header file must be used:
// Header file for vector
#include<vector>
After including the header file, then it is easy to initialize the vector object.
“#include vector” header file must be included to define the vector in a
Syntax:
Syntax to define a vector is as follows:
//syntax for declaring a vector with size
vector <data_type> name_of_vector(no_of_elements);
In the above line,
- The keyword “vector” represents the vector declaration.
- The “<data_type>” represents the type of data the vector can hold; the data types such as “int”, “float”, “string”, “char”, and “double”.
- The “name_of_vector” represents the name of the vector.
- The “no_of_elements” inside the brackets refers the number of elements that the vector can hold.

This ALU will implement a bitwise left rotation. Forthis lab assignment you are not allowed to use Digital's Arithmetic components.IF YOU ARE FOUND USING THEM, YOU WILL RECEIVE A ZERO FOR LAB2!The ALU you will be implementing consists of two 4-bit inputs (named inA and inB) and one 4-bit output (named out). Your ALU must rotate the bits in inA by the amount given by inB (i.e. 0-15).Part-1: User InterfaceYou are provided an interface file lab2_part1.dig; start Part-1 from this file.NOTE: You are not permitted to edit the content inside the dotted lines rectangle. Part-1: ExampleIn the figure above, the input values that we have selected to test are inA = {inA_3, inA_2, inA_1, inA_0} = {0, 1, 0,0} and inB = {inB_3, inB_2, inB_1, inB_0} = {0, 0, 1, 0}. Therefore, we must rotate the bus 0100 bitwise left by00102, or 2 in base 10, to get {0, 0, 0, 1}. Please note that a rotation left is…arrow_forward
