In my assignment I am supposed to use a pointer to create a 2-D array dynamically. Initialize each element in the array to the sum of its row and column. Then display each element of the array on the console.
I have the program written and it works except for the part that says initialize each element in the array to the sum of its row and column.
For the life of me I cannot wrap my head around how to do that. Can anyone give me a little help or suggestion as to a best method. I have set it to initialize everything to zero at the moment.
I tried doing this with no success
for (int j=0;j<5;j++) //initalize array elements to sum of row and column
{
for (int i=0;i<5;i++)
p[i][j]=i+2;
}//Scott
// Homework Chapter 14A
#include "stdafx.h"
#include <iostream>
#include <iomanip>
#define frz system("pause");
using namespace std;
int main()
{
int **p;
p=new int* [5];//creates 2 rows
for(int row=0;row<5;row++)//creates 2 columns
p[row]=new int[5];
cout<<"Base address of memory pointer: "<<p<<endl;
for (int j=0;j<5;j++) //initalize array elements to sum of row and column
{
for (int i=0;i<5;i++)
p[i][j]=0;
}
for (int j=0;j<5;j++)
{
for (int i=0;i<5;i++)
cout<<setw(5)<<p[i][j];
cout<<endl;
}
cout<<endl;
p=NULL;
delete [5] p; //deallocate dynamic memory
cout<<"Base address of memory pointer: "<<p<<endl;
cout<<endl;
frz;
return 0;
}
