Aim: To implement a program to allocate memory dynamically for 2 dimensional array (accept and print matrix) using pointers.
Code:
#include
class matrix
{
int **p,r,c,i,j;
public:
matrix(int,int);
~matrix();
void getdata();
void display();
};
matrix::matrix(int x,int y)
r=x;
c=y;
p=new int *[r];
for(i=0;i p[i]=new int [c]; } matrix::~matrix() { for(i=0;i delete p[i]; delete p; cout<<"\nMemory deallocated successfully\n"; } void matrix::getdata() { cout<<"\nEnter matrix values:\n"; for(i=0;i { cout<<"Enter values for row:"< for(j=0;j cin>>p[i][j]; } } void matrix::display() { cout<<"\nThe matrix is:\n"; for(i=0;i {; for(j=0;j cout< cout< } } void main() { int rows,cols; clrscr(); cout<<"Enter number of rows and columns for a matrix\n"; cout<<"Enter number of rows\n"; cin>>rows; cout<<"Enter number of columns\n"; cin>>cols; matrix A(rows,cols); A.getdata(); A.display(); getch(); } Output: Enter number of rows and columns for a matrix Enter number of rows 3 Enter number of columns 3 Enter the values of the matrix Enter values for row 1 1 2 3 Enter values for row 2 4 5 6 Enter values for row 3 7 8 9 The matrix is 1 2 3 4 5 6 7 8 9 Memory deallocated successfully
p[i]=new int [c];
}

Enter the values of the matrix
Enter values for row 1
1 2 3
Enter values for row 2
4 5 6
Enter values for row 3
7 8 9
The matrix is
