Exercise 2: Fill in the code so that the program reads in the data values from the temperature file and prints them to the screen with the following output:

78.90

87.40

60.80

70.40

75.60

Exercise 3: Add code (member function, call and function implementation) to print the average of the numbers to the screen so that the output will look like the output from Exercise 2 plus the following:

The average temperature is 74.62

float FloatList::findAverage() const

{

float sum = 0;

for (int count = 0; count < length; count++)

sum = sum + values[count];

return sum / length;
