Member Function outputBarChart
Finally, line 52 in member function
processGrades calls member function
outputBarChart to print a distribution chart of the grade data using a technique similar to that in Fig. 7.9. In that example, we manually calculated the number of grades in each category (i.e., 0–9, 10–19, ..., 90–99 and 100) by simply looking at a set of grades. In this example, lines 110–111 use a technique similar to that in Fig. 7.10 and Fig. 7.11 to calculate the frequency of grades in each category. Line 107 of Fig. 7.16 declares and creates
array frequency of 11
unsigned ints to store the frequency of grades in each grade category. For each
array grades, lines 110–111 increment the appropriate element of the
frequency array ...
