In compiler theory, a reaching definition for a given instruction is an earlier instruction whose target variable can reach the given one without an intervening assignment. For example, in the following code: d1: y:= 3 d2: x:= y d1 is a reaching definition for d2. In the following, example, however: d1: y:= 3 d2: y:= 4 d3: x:= y d1 is no longer a reaching definition for d3, because d2 kills its reach: the value defined in d1 is no longer available and cannot reach d3.
Many maintenance projects come down to price. After all, if they were free, the only cost would be time. According to our carpet cleaning cost estimator, the average price to clean a carpet is $167.

Average carpet prices start at $2 a square foot and increase with quality. Middle-grade quality carpet ranges from $3 to $4 a square foot, and high grades and designer grades cost about $5 or more per square foot. According to Costhelper, if it's not already included in the cost, expect to pay an additional $2.50 to $6 per square foot for padding, and $2 to 6 per square foot for installation. Be wary of free padding promotions or low-cost carpet deals.
