Question

In a given polynomial, enter the coefficient 'cf' as a parameter and create the member function 'numofCoeff', which returns the number of terms with the same coefficient as 'cf'.

class Polynomial; // 전방 선언

    class Term {

    friend Polynomial; // Polynomial 클래스에서 접근 가능

    private:

         float coef;  

        int exp;

    };

class Polynomial {

    private:   

Term *termArray;

int capacity;

int terms;

public:

....

}

int Polynomial:numofCoeff(float cf)

Answer 1

CODE:

int Polynomial:numofCoeff(float cf)

{

    int count = 0;

    //Iterate through all the terms

    for(int i = 0;i < terms;++i)

    {

        //For each term check the coefficient against the param

        if(termArray[i].coef == cf)

        {

            ++count;

        }

    }

    return count;

}
