Imagine a class of 7 students that have a quiz every week for 5 weeks. The instructor records the grades in a table. A particular cell of the table is designated by student number and week number. For example:

• The grade for student 0 week 1 is 42
• The grade for student 3 week 4 is 93
• The grade for student 6 week 2 is 78

A compact notation for specifying a cell uses the row and column indexes like this:

gradeTable[ row ][ col ]

For example:

• gradeTable[ 0 ][ 1 ] is 42
• gradeTable[ 3 ][ 4 ] is 93
• gradeTable[ 6 ][ 2 ] is 78
