- When writing C# code, how do you indicate a namespace? Question options: You must specify the namespace by using the "namespace" keyword, followed by the namespace. You must use the "declare namespace" keywords, followed by the namespace. You must utilize the using clause, or using directive, by specifying "using", followed by the namespace. You must use create a file called "namespaces", and include all namespace code in this file. Then, the namespace can be used by name in your program. Question 14Write a menu driven C++ program to do the following: 1. Read Employees information from a data file: Name, Hrs work, rate of pay 2. Write the following data to an output text file.

- make a program in c++ which has a class named Student. The class should have appropriate data members to store the enrollment number, name and email of a student. make an appropriate function for taking the basic information like enrollment number, name and email from user. In addition, make another function to append the data to a text file on hard disk. Furthermore, there should be a function which displays the content of the file on console. In the main function create objects of the above class and call the appropriate functions to add information of a student, store it in a file and display on the consolePlease use strtol and strtod. Please have the int main function first as well and write in C++. Develop a C++ program that reads an unsigned number in some base and outputs theequivalent value in a target base. The input file providing these values will be organized toallow for comment lines and blank lines along with data lines. Use only a single source file so Ican more easily script the downloading and compiling of your submissions.Your program must require a single command line argument, the name of an input file. Thisinput file will consist of any number of lines, each falling into one of three varieties:1. Comment - These lines always start with an at-symbol ('@') and should be completelyignored.2. Blank line - Used to visually organize the input file and should be completely ignored.3. Data line - These are the ones your program will process and are described below.Data lines will all have exactly 3 items separated by a single space character and end with anewline:1. an input…I need help in this question in C program. Assume the following declarations:struct EmployeeTag{char name[40];int ID_number;float salary;};typedef struct EmployeeTag EmployeeType; Write a program that will read employee structure one at a time from the file "employee.dat" created in the previous problem. The value of each structure should be displayed on the standard output device.
