Creating matrix using array

February 24, 2022

I made an array matrix and used for loops, the problem is that it only displays my last input. Please refer to the sample result below.

#include<iostream>
using namespace std;
int main()
 {
   int x = 0, y = 0;
   int a[x][y], i, j;

cout<<"Enter number of Columns: ";
cin>>y;

cout<<"Enter number of Rows: ";
cin>>x;

       cout<<endl;

 for(i=0; i<x; i++)
{
        cout<<endl;
        cout<<"Enter values or row/s: ";
        cout<<endl;
                            
for(j=0; j<y; j++)
{
    cout<<endl;
    
    cout<<"Row "<< i+1 << ": ";
    cin >> a[i][j]; 
   }
   }

cout<<endl;

cout<<"Entered Matrix is: ";

cout<<endl;

for(i=0; i<x; i++)
{
    for(j=0; j<y; j++)
    
        cout<<a[i][j]<<"  ";
        
    cout<<endl;
    
     }


   }

SAMPLE RESULT:

Enter number of Columns: 3

Enter number of Rows: 2

Enter values or row/s:

Row 1: -1

Row 1: -2

Row 1: -3

Enter values or row/s:

Row 2: 4

Row 2: 5

Row 2: -6

Entered Matrix is:
