Program Of Array of Constructor Parameter In C++

#include<iostream.h>

#include<conio.h>

class add

{

private:

int x,y;           // Data Member

public:

add(int p,int q)   // Default Parameter Constructor

{

x=p;

y=q;

}

void display()

{

int r;

r=x+y;

cout<<"\n NAswer="<<r;

}

};

main()

{

clrscr();

int i;

add a[3]={add(2,4),add(5,7),add(9,10)};

for(i=0;i<3;i++)

{

a[i].display();

}

getch();

}

  In this section we consider the Array<T> class constructor which takes two numeric arguments of type unsigned int. The definition of this constructor is given in Program . Given argument values m and n, the constructor first allocates an array of n elements of type T using operator new, and then sets the length field to n and the base field to m. The running time is a constant plus the time do the array allocation.
