Complete the C++ skeleton program you have been given. The skeleton contains the function declarations, a driver, and empty function definitions. The program currently runs. However, there are several modification you should make for the program to be complete. You will need to implement the empty functions AND make calls to these functions in the main function.

Below is a list of the functions you will need to implement:

void RepeatDisplay(string st, int num);

int SumDigits(int num);

string RepeatItem (string st, int num);

void StringToFile (string filename, string stuff);

void PrintTriangle(int dimension);

int CountVowels (string st);

Further descriptions of these functions can be found in the in the provided source code file:

//Function: RepeatDisplay

//Purpose: This function should print the given string

// num times

//Incoming: name contains the string to be printed

//Function: RepeatItem

//Purpose: This function concatenates the 1st parameter to

// an empty string num times, where num is the

// 2nd parameter. Return the new string

//Incoming: str contains the original string

//Function: StringToFile

//Purpose: This function will open an output file stream

// using the given string (1st parameter). If

// a successful open, the 2nd parameter will be

// printed to the file. If the file does fails

// to open, and error message should be printed

// to the screen.

//Incoming: filename will hold the name of the file to be

// opened for writing

// stuff will hold the string to be written to the

// file

//Outgoing: N/A

//Return: N/A

//Function: PrintTriangle

//Purpose: This function prints a triangle in the form

// X

// based upon the dimension given

//Incoming: row and column dimension (will be same, so one parameter is sent

//Outgoing: N/A

//Return: N/A
