Question

What is the difference between P-uses and C-uses of a variable in dataflow analysis?

a.

P-uses are used in computations, while C-uses are used in predicates

b.

P-uses are used in predicates, while C-uses are used in computations or I/O statements

c.

P-uses are used in I/O statements, while C-uses are used in computations or predicates

d.

P-uses are used in computations or I/O statements, while C-uses are used in predicates

Posted under Software Testing Software Engineering

Answer: (b).P-uses are used in predicates, while C-uses are used in computations or I/O statements Explanation:P-uses are predicate uses, such as those in the conditional part of an if-statement, while all other uses are C-uses.
