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.
