C++ plz

read the question carefully, use the main function provided in the following image do the extra credit part that is highlighted in the PDF, I will rate ur answer, ty!

Description: This assignment is to write a program that reads a set of strings from the standard input (keyboard), generates all permutations of that the strings, and then display the results to the standard output (screen) You may use any of the standard library types (e.g., the containers that we learned in the class) in your implementation, including library functions from the library that generate permutations. You will need to study functions related to permutation in the library by yourself if you decide to do so. Or you may write code to generate permutations on your own. Be sure to include the reference(s) that you learn the library or how to_generate ermutations A permutation is defined as an ordered arrangement of a set of objects. For example, the following set of three distinct strings would have six permutations: Strings: "ab" "c" "de" Permutations: 1. ab c de 2. ab de c 3. c ab de 4. c de ab 5. de abc 6. de c alb Here is some information about the algorithm library http://www.cplusplus.com/reference/algorithm/ You may use the following code as a starting point. You'll need to implement generate_permutations and print_permutations functions
