Explanation of Solution
Class template:
In C++, a class template is used to create a common version of a class and it does not have any additional code for handling multiple data types.
Defining class template objects:
Definition of class template object is little different from normal class object definition.
- The difference is, to specify the data type that user want to pass as the type parameter.
- This data type should be placed inside a pair of an angle brackets, which is followed by the class name is as follows:
Class_name<int> object_name;
From the above declaration, “int” is a data type for the type parameter of the given class.
Example:
For example, consider the following program which is used to square the given value of any types, in which the class template “List” has been defined and its object has been defined in main() function:
//include the required header files
#include <iostream>
using namespace std;
//class template
template<class T>
//definition of the template class
class List
{
//declare the class data member
T x;
//access specifier for the class member functions
public:
//default constructor
List()
{
x=0;
}
//this member function is used to get the user input
void getvalues()
{
//get the value from the user
;&#x...

- (a) Algebraically determine the output state |q3q2q1q0> (which is a 4-qubitvector in 16-dimensional Hilbert space). Show all steps of your calculations. (b) Run a Qiskit code which implements the circuit and append threemeasurement gates to measure the (partial) output state |q2q1q0> (which is a 3-qubit vector in 8-dimensional Hilbert space). this is for quantum soft dev class, you can use stuff like Deutsch Jozsa if u wantarrow_forwardWrite a C++ program that will count from 1 to 10 by 1. The default output should be 1, 2, 3, 4, 5, 6 , 7, 8, 9, 10 There should be only a newline after the last number. Each number except the last should be followed by a comma and a space. To make your program more functional, you should parse command line arguments and change behavior based on their values. Argument Parameter Action -f, --first yes, an integer Change place you start counting -l, --last yes, an integer Change place you end counting -s, --skip optional, an integer, 1 if not specified Change the amount you add to the counter each iteration -h, --help none Print a help message including these instructions. -j, --joke none Tell a number based joke. So, if your program is called counter counter -f 10 --last 4 --skip 2 should produce 10, 8, 6, 4 Please use the last supplied argument. If your code is called counter, counter -f 4 -f 5 -f 6 should count from 6. You should count from first to last inclusively.…arrow_forwardWrite a program that will count from 1 to 10 by 1.

- A Dia file has been created for you to extend and can be found on Company.dia represents a completed ER schema which, models some of the information implemented in the system, as a starting point for this exercise. Understanding the ER schema for the Company database. To demonstrate that you understand the information represented by the schema, explain using EMPLOYEE, DEPARTMENT, PROJECT and DEPENDENT as examples: attributes, entities and relationships cardinality & participation constraints on relationships You should explain questions a and b using the schema you have been given to more easily explain your answers. Creating and Extending Entity Relationship (EER) Diagrams. To demonstrate you can create entity relationship diagrams extend the ER as described in Company.dia by modelling new requirements as follows: Create subclasses to extend Employee. The employee type may be distinguished further based on the job type (SECRETARY, ENGINEER, MANAGER, and TECHNICIAN) and based…arrow_forwardComputer programs can be very complex, containing thousands (or millions) of lines of code and performing millions of operations per second. Given this, how can we possibly know that a particular computer program's results are correct? Do some research on this topic then think carefully about your response. Also, explain how YOU would approach testing a large problem. Your answer must be thoughtful and give some insight into why you believe your steps would be helpful when testing a large program.arrow_forwardCould you fix this?
