EXAMPLE 9.3 Two-Dimensional Array Processing

Data for family cell bills

row 0: 45.24 54.67 32.55 25.61

row 1: 65.29 49.75 32.08 26.11

row 2: 75.24 54.53 34.55 28.16

9.3.2 Processing a Given Row of a Two-Dimensional Array

What if we want to process just one row of a two-dimensional array? For

instance, we could be interested in calculating the sum of the cell bills for

the whole family for a particular month, or identifying who had the highest

cell bill in a particular month.

The general ...
