Operations of vector class

The vector class is available in Java and C++ programming languages. It is a class implementing a dynamic array. A dynamic array is an array whose size automatically increases when an element is added to it. The vector class stores elements in a contiguous memory block and assigns the memory to the elements whenever required during execution.

Phyton: Program 6: Write a program that allows the user to add data from files or by hand. The user may add more data whenever they want. The print also allows the user to display the data and to print the statistics. The data is store in a list. It’s easier if you make the list global so that other functions can access it. You should have the following functions: · add_from_file() – prompts the user for a file and add the data from it. · add_by_hand() – prompts the user to enter data until user type a negative number. · print_stats() – print the stats (min, max, mean, sum). You may use the built-in functions. Handling errors such as whether the input file exist is extra credit. To print a 10-column table, you can use the code below: for i in range(len(data)): print(f"{data[i]:3}", end="") if (i+1)%10==0: print() print() Sample run: Choose an action 1) add data from a file 2) add data by hand 3) print stats 4)…
