Question

Consider the following code snippet:

showPrimes - display n prime numbers; utilize counting loop and the loop instruction to keep track of the number of primes displayed; candidate primes are generated within counting loop and are passed to isPrime for evaluation
isPrime - receive candidate value, return boolean (0 or 1) indicating whether candidate value is prime (1) or not prime (0)

What is the purpose of the isPrime function?

A. Evaluate the loop instruction
B. Display prime numbers
C. Generate candidate primes
D. Determine if a candidate value is prime

Answer 1

The isPrime function determines if a candidate value is prime by checking if it is divisible by any number other than 1 and itself.

Step-by-step explanation:

The purpose of the isPrime function is to determine if a candidate value is prime.

To check if a number is prime, the isPrime function takes a candidate value as input and returns a boolean (0 or 1) indicating whether the candidate value is prime (1) or not prime (0).

It does this by evaluating whether the candidate number is divisible by any number other than 1 and itself. If it is divisible by any number other than 1 and itself, it is not prime; otherwise, it is prime.
