e) Translates programs into machine language.

Consider a table composed of an array INUM of item numbers, an array PRICE
of prices, and an array CGST of unit costs. We wish to look for the value
of the variable NUM in the item number array so as to determine its price
and unit cost.

NUM is called the s

INUM is called the s

PRICE and CGST are called s
