hi, i have a problem with this, please be sure that this is not to ask for answer, this is to ask for what i want to do

actually i have written some of the code but i have stuck with ...can someone give me some advice on what should i do. i am not asking for answer...

this is my code:

Code:
#include <iostream>
#include <cstdlib>
using namespace std;

int main()
{
    int n;
    
    cout<<"Please enter how many integers per line [ 1 < 100 ]: ";
    cin>>n;
    
    int row = n;
    int col = n;
    int matrix[row][col];
    
//assign limitation between values
    
    if(n<100 && n>0)
    {
//initialize and insert values into the matrix   

        for(int row = 0; row < n; row++)
        {
                for(int col = 0; col < n; col++)
                
                        cin>>matrix[row][col];
        }   
    
//sum each row

        for(int row = 0; row < n; row++)
        {
            int sumRow = 0;
            
            for(int col = 0; col < n; col++)
            {
                sumRow = sumRow + matrix[row][col];
                cout<<"sum of row "<<row+1<<" = "<<sumRow<<endl;
            }    
//sum each column

        for(int col = 0; col < n; col++)
        {
            int sumColumn = 0;
            
            for(int row = 0; row < n; row++)
            
                sumColumn = sumColumn + matrix[row][col];
                cout<<"sum of column "<<col+1<<" = "<<sumColumn<<endl;
        }


//check parity 



    }
    else
    {
        return 1;
    }         
system("pause");
return 0;
}
