The task is to write a C++ program that inputs this data into a 1D array and then outputs the average (as a real number). Your job is to write the main() function by per line. The file name is "dataset.txt", and the file calling the provided InputData() and ComputeSum() functions. Write only the main() function, assume the other functions have already been written for yousee the comment inside each function for the tasks they perform. Your main() function is responsible for all other operations #include #include #include #include using namespace std; int InputData(string filename, double data[ ) // opens filename, inputs data into array, returns # of values input: double ComputeSum(double data[], int N) /I returns sum of first N values in the array: int main()
