Person/Number of Commodities to be brought	Laptop	Mouse	Headset	Laptop Bag	Adapter
Ramu	5	15	10	5	20
Raju	10	10	25	10	15
Shyam	3	5	6	3	10

#include <iostream>
using namespace std;
int main()
{

int arr[3][5] ={

{5,15,10,5,20},
{10,10,25,10,15},
{3,5,6,3,10}
};
int i, j;
for (i = 0; i < 3; i++)
{
for (j = 0; j < 5; j++)

cout << *(*(arr + i) + j) << "\t";
cout <<"\n";
}
return 0;
}

Output:

Next i have to display the vendor price list:

#include <iostream>
using namespace std;
int main()
{

int arr[2][5] ={

{45000,1500,2500,1200,1600},
{43000,1200,3000,1000,1500},
};
int i, j;
for (i = 0; i < 2; i++)
{
for (j = 0; j < 5; j++)

cout << *(*(arr + i) + j) << "\t";
cout <<"\n";
}
return 0;
}

Output:

Now i have to find the difference and find the best minimum difference:

#include <iostream>
#include<conio.h>

using namespace std;

int main()
{
int rowCount, columnCount, i, j;
int firstMatrix[10][10], secondMatrix[10][10], resultMatrix[10][10];

cout<<"Simple C++ Example Program for 2 D (dimensional) Array Matrix Subtraction Example\n";

cout<<"Number of rows of matrices to be subtracted : ";
cin>>rowCount;

cout<<"Number of columns matrices to be subtracted : ";
cin>>columnCount;

cout<<"Elements of first matrix : \n";

for (i = 0; i < rowCount; i++)
for (j = 0; j < columnCount; j++)
cin>>firstMatrix[i][j];

cout<<"Elements of second matrix : \n";

for (i = 0; i < rowCount; i++)
for (j = 0; j < columnCount; j++)
cin>>secondMatrix[i][j];

cout<<"Difference of entered matrices : \n";

for (i = 0; i < rowCount; i++)
{
for (j = 0; j < columnCount; j++)
{
resultMatrix[i][j] = firstMatrix[i][j] - secondMatrix[i][j];
cout<<resultMatrix[i][j]<<"\t";
}
cout<<"\n";
}

getch();

return 0;
}

output:

Hence the Vendor 2 is the best vendor.
