outputGrades (lines 140–165) uses nested counter-controlled
for statements to output values of the
array grades, in addition to each student’s semester average. The output in Fig. 7.21 shows the result, which resembles the tabular format of a professor’s physical grade book. Lines 146–147 print the column headings for each test. We use a counter-controlled
for statement so that we can identify each test with a number. Similarly, the
for statement in lines 152–164 first outputs a row label using a counter variable to identify each student (line 154). Although
array indices start at 0, lines 147 and 154 output
test + 1 and
student + 1, respectively, to produce test and student numbers starting at 1 (see Fig. ...
