write my assignment 984

Hi i need help with this c++ assignment

• Write a recursive function that will sum every element with an odd subscript in an integer array. Write the function so that it can accept an array of any size.
• Return the sum from the function.
• Write a recursive function that will display a string in reverse order. Remember that individual characters of a string may be accessed using bracket notation or the at() function
• Use default arguments so that the function can be called with a single string argument.
• Write a main driver function that tests both of the recursive functions.
