Full description about vector in Vector
Use do,while to create a loop that runs once before checking the condition.
Use switch to facilitate and reduce the number of if and esle ifs and make the program lighter to run.
Use the empty() command in the vector to check if the vector is empty or not.
Use the auto access modifier to allow the program to detect the type of variable inside the vector in the for (auto number : numbers) command.
Create an infinite while loop to receive a number from the user on line 57 of the program and place the number in the vector with the push_back() command. In this loop, the exit is in the hands of the user, so that if the user enters the number -1, the condition of the loop becomes false and the program exits the loop.
