Problem: Write a C++ program to take the dimensions of a matrix (m,n) as input from the user. The program should then take the matrix (let us call it A) itself as input from the user. Following this, the program should compute the product of the transpose of A with A (i.e. ATA of size n x n) and display the result. To accomplish this task, write a function of the form void compute_matrixtranspose_matrix_product (int A[][MAX], int m, int n, int ATA[][MAX]).

Problem: Write a C++ program to take the dimensions of a matrix (m,n) as input from the user. The program should then take the matrix (let us call it A) itself as input from the user. Following this, the program should compute the product of the transpose of A with A (i.e. ATA of size n x n) and display the result. To accomplish this task, write a function of the form void compute_matrixtranspose_matrix_product (int A[][MAX], int m, int n, int ATA[][MAX]).

Constraints
n is a positive integer, m,n <= 8

Student submission:
#include <iostream>
using namespace std;
#define MAX 100
void compute_matrixtranspose_matrix_product(int A[][MAX],int m, int n,int AtA[][MAX]){
	int **At = new int*[n]; 
	for(int i=0;i<n;i++){
		At[i] =  new int [m];
	}
	for (int i = 0; i<n;i++){
		for (int j=0; j<m;j++){
			At[i][j]=A[j][i];
		}
	}
	for (int i = 0;i<n;i++){
		for (int j = 0; j<n;j++){
			AtA[i][j]=0;
			for (int k=0;k<m;k++){
				AtA[i][j]+=At[i][k]*A[k][j];
			}
		}
	}
	for(int i=0;i<n;i++) delete [] At[i];
delete [] At;

			cin >> A[i][j];
		}
	}
}
void display(int AtA[][MAX],int n){
	for (int i =0;i<n;i++){
		for (int j=0;j<n;j++){
			cout << AtA[i][j]<<" ";
		}cout<<endl;
	}

	get_input(A,m,n);
	compute_matrixtranspose_matrix_product(A,m,n,AtA);
	display(AtA,n);
	return 0;
