Write in C++ Now, what if Sam wants to insert Eevee after Pikachu but he doesn't know where Pikachu is located in his list. Let's help him search for a Pokemon by its name and insert another Pokemon directly after it. Write a function secondPlace() that takes six parameters and inserts a new Pokemon into a list right after another specified pokemon. Once you find the specified Pokemon, use the insertAfter() function from the previous sub-question to add the new Pokemon. The function should return the new number of strings in the array. Note The same Pokemon may appear in the list multiple times (Sam has a bad memory). Assume that Sam wants every instance of the Pokemon he is searching for to be followed by the Pokemon he is attempting to insert. If the array is already full or if the number of strings that are going to be added to the array plus the current number of strings exceeds the total size of the array, the array should remain unchanged. Assume all inputs are lowercase…

1. Create a UML using the UML Template attached. 2. In this lab, you will be creating a roulette wheel. The pockets are numbered from 0 to 36. The colors of the pockets are as follows: Pocket 0 is green. For pockets 1 through 10, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 11 through 18, the odd-numbered pockets are black and the even-numbered pockets are red. For pockets 19 through 28, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 29 through 36, the odd-numbered pockets are black and the even-numbered pockets are red. Create a class named RoulettePocket. The class's constructor should accept a pocket number. The class should have a method named getPocketColor that returns the pocket's color, as a string. Demonstrate the class in a program that asks the user to enter a pocket number, and displays whether the pocket is green, red, or black. The program should display an error message if the user…
