Consider a program that computes the factorial of a number (n). From the specifications you know that: If n < 0, a message "Value out of range" must be issued. If 0 < n < 100, the program calculates…

Options

• AThere are 3 partitions - one for negative numbers, one for numbers up to 100 and the last one
• BThe equivalence partitions cannot be determined for this question because the error message
• CThe requirements are not correct because the partitions are overlapping
• DThe equivalence partitions cannot be determined for this question because factorial of

• D

Explanation

Equivalence partitioning involves dividing input data into partitions that are treated the same by the system under test. The given specifications create overlapping partitions: For n<0n < 0n<0, an error message "Value out of range" is issued. For 0<n<1000 < n < 1000<n<100, the factorial is calculated. For 100<n<200100 < n < 200100<n<200, the same error message "Value out of range" is issued. However, the range between 0 and 100 is exclusive of 0 and 100, meaning that the partitions overlap and create ambiguity for the boundary values. Thus, the correct statement is that the requirements are not correct because the partitions are overlapping.
