Using the C++ STL and assuming you have a vector of integers called V1, a) Write a statement to sort the elements of the vector. b) Write a statement to sort the elements and make sure the order of equal keys is retained  in the sorted output.

A1: File Handling with struct C++   This program is to read a given file and display the information about employees according to the type of employee. Specifically, the requirements are as follows. Read the given file of the information of employees. Store the information in an array or arrays. Display all the salaried employees first and then the hourly employees Prompt the user to enter an SSN and find the corresponding employee and display the information of that employee.

Declare a vector of integers in C++ named vec and initialize the vector to 10, 20, 30, 40, and 50. Modify the first element of the vector to be 100 and modify the last element to be 1000. The resulting vector should then be 100, 20, 30, 40, and 1000. Using cout statements, display the resulting vector to the terminal.

Write the following function #input: a numerical vector x #output:the normalized vector, i.e. the vector rescaled into [0,1] # the formula to normalize is (x-min(x))/ (max(x)-min(x)) # you can NOT use the functions min and max # you can use %%, nrow, ncol, and length # you can write multiple functions
