ReverseArray

create your own class, allocate that class in main, and define these methods inside that class, calling them from the Main method.
Create a method called CopyArray that takes an array of ints and allocates a new array which is an exact copy of all the data from that array and returns that array (remember, you can't just say copy = oldArray because the value of the variable is the address in memory, not the data that is stored there).
Create a method called ReverseArray that takes an array of ints and reverses all the elements (without creating another array). This means the first element would now be the last, the second element would be the second to last, etc.
Create a method called FindEvens that takes an array of ints, and returns an array containing the index of each element in the array that is even. For example if you passed in an array array {33 21 20 55 88 100 71 68} it would return an array {2 4 5 7} (hint: you first need to find out how big the array you're returning is).
Create a method called IsCapitalized that takes a string and returns true if the first letter is capitalized.
Create a method called CountCapitals that takes a string and returns how many capital letters are in it (you must write this method yourself, do not just use something built-in to C#)
Create a method called FindFirstCharacter that takes a string and a character and returns the index of where that character was first found (returning -1 if it was not found)
Create a method called Capitalize that takes a string and returns a string where every letter is capitalized.
Create a method called LowerCase that takesa string and returns a string where every letter is lower case.
