If a function prototype using a call by reference using pointers is int CalcInfo(float * p1, float * p2); how would you write the same prototype using a call by reference using reference parameters?
A. int CalcInfo(float p1, float p2); B. int CalcInfo(float r1, float r2); C. int CalcInfo(&*p1, &*p2); D. int CalcInfo(float &r1, float &r2);
Assume that programs and data may be shuttled from any level to any other level under the operating system’s control.The time it takes to transfer items between two particular levels is dependent upon the speed of the lowest (and slowest) level involved in the transfer.Why might the operating system choose to shuttle a program from cache directly to secondary memory, thus bypassing primary memory?

An adjustment layer is called "____" because it exists as a layer on the Layers panel.
A. singular B. non-destructive C. safe D. base
Let there be an unclustered hash index on ProfId and assume that, as before, 5 Professor tuples ?t in one page, 10 Teaching tuples ?t in one page, and the cardinality of Teaching is 10,000. Estimate the cost of computing the above join using index-nested loops and block-nested loops with a 51-page bu?er.
Consider the join Professor Id=ProfId Teaching used in the running example of Section 11.3. Let us change the statistics slightly and assume that the number of distinct values for Teaching.ProfId is 10,000 (which translates into lower weight for this attribute).
