Question

C++Implement only (source code) a program to determine whether two two-dimensional arrays are equivalent or not. Two arrays are equivalent if they contain the same values in any order. The program main method defines two two-dimensional array of size 3-by-3 of type integer, and prompts the user to enter integer values to initialize the arrays. The main method calls method isEquivalent()that takes two two-dimensional arrays of integer and returns true (boolean value) if the arrays contain the same values in any order, otherwise it returns false. Hint: use a sort method from Lab 14 in developing the solution for this problem. Document your code and properly label the input prompts and the outputs as shown below. Sample run 1: Array A: 1 2 3 4 5 6 7 8 9 Array B: 1 2 3 6 5 4 7 8 9 Judgment: The arrays are equivalent. Sample run 2: Array A: 1 1 1 1 5 6 1 1 1 Array B: 1 1 1 1 6 6 1 1 1 Judgment: The arrays are not equivalent.

Answer 1

#include<iostream>
using namespace std;
bool isEquivalent(int [][3],int [][3]);
int main()
{
int a[3][3];
int b[3][3];
int i,j,k,l;
cout<<"Enter elements for matrix A.\n";
for(i=0;i<3;i++)
for(j=0;j<3;j++)
cin>>a[i][j];
cout<<"Enter elements for matrix B.\n";
for(i=0;i<3;i++)
for(j=0;j<3;j++)
cin>>b[i][j];
cout<<"\nMatrix A:\n";
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
cout<<a[i][j]<<" ";
cout<<"\n";
}
cout<<"\nMatrix B\n";
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
cout<<a[i][j]<<" ";
cout<<"\n";
}
bool res;
res = isEquivalent(a,b);
if(res == true)
cout<<"Judgement: The arrays are equivalent.";
else
cout<<"Judgement: The arrays are not equivalent.";
return 0;
}
bool isEquivalent(int a[3][3] , int b[3][3] )
{
int i,j,count=0,temp,k,l;
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
temp=a[i][j];
for(k=0;k<3;k++)
{
for(l=0;l<3;l++)
{
if(temp == b[k][l])
count++;
}
}
}
}
if(count==9)//because there are only 9 elements in 3X3 matrix.
return true;
else
return false;
