C++ Question:
Consider the following class called Myscores that stores all the scores for a game.
class Myscores {
public:
Myscores() { // constructor
nScores = 0;
}
void addScore(int newscore) {
score[nScores] = newscore;
nScores++;
}
private:
int score[10];
int nScores; // number of scores stored
};
i) The score member variable can store at most 10 scores. Change the code so that score can store as many scores as needed when a Myscores object is created. (Hint: use dynamic memory). Change/add constructor and destructors as needed.
ii) Add a copy constructor for the above case.
Explanation / Answer
#include <iostream>
using namespace std;
class Myscores{
private:
int n;
int *scores;
int nScore;
public:Myscores(){
nScore=0;
}
Myscores(int n){
scores = new int[n];
}
~Myscores()
{
delete[] scores;
}
Myscores(const Myscores &m){
nScore=m.nScore;
if(m.scores){
scores= new int[nScore];
for(int i=0;i<nScore;i++)
{
scores[i]=m.scores[i];
}
}
else
scores=0;
}
void addScore(int newscore)
{
scores[nScore] = newscore;
nScore++;
}
};
