2a Question 2a . Declare a class SNAP ("static, mumber, array, pointer") as follows. . The data in class SHAP is statie string st, number int n, array int ta, pointer int "p . A non-default constructor is written for you. 1. The pointer p is dynamically allocated to a single object. 2. The pointer a is dynamically allocated to an array of length n. 3. You are given n> 0. class SNAP public: SNAP(int x, int m) // given to you // you are given that m> o n # m; a new int [n]; p new int; for (int i 0; i

Explanation / Answer

If you have any doubts, please give me comment...

#include<iostream>

#include<string>

using namespace std;

class SNAP{

public:

SNAP(int x, int m){

n = m;

a = new int[n];

p = new int;

*p = x;

for(int i=0; i<n; ++i)

a[i] = 0;

}

int get_n() const{

return n;

}

string get_st(){

return st;

}

void set_st(string s){

st = s;

}

SNAP(){

n = 0;

a = NULL;

p = NULL;

}

SNAP(const SNAP &copy):SNAP(*(copy.p) ,copy.get_n()){

}

SNAP& operator=(const SNAP &c){

if(this == &c)

return *this;

this->n = c.n;

this->a = new int[c.n];

this->p = new int;

this->p = c.p;

for(int i=0; i<c.n;i++)

this->a[i] = c.a[i];

return *this;

}

~SNAP(){

delete[] a;

delete p;

}

private:

static string st;

int n;

int *a;

int *p;

};

string SNAP::st = "SNAP";
