Chapter 4.2, Problem 16SCP

Explanation of Solution

Given code snippet:

//define the static function  

public static int countFactors(int n) {

    //loop to derive the factors   

    for (int i = 1 ; i <= n; i++) {

        //condition to check the number of factors  

        if (n %i == 0) {

            //return statement  

            return i;

        }

    }

}

Error in the above code:

• In the given code snippet, the method “countFactors” will not compile.
• This method should count the factors with the use of cumulative sum and should not return inside the loop when it finds each factor.
• It should declare a counter outside the loop that is incremented as each factor is seen...
