I have written a code to add matrices,the code is all fine the only problem is that when i m printing the output it is looking something like this 12 12 12 12 12 instead of this i want it as 12 12 12 12 12 12 12 12 12..Can u please help me...

In a later lesson you learn how to do this at run time instead of at the time it's compiled. In either case, the size does have to be dimensions do have to be known beforehand. You can use a function or a class to determine the length and number of rows from the file. Arrays have to be initialized with the dimension size.

How could a "while" be controlled when filling an array from a file? Great, but if you don’t know the length of the actual number of rows, the outer loop can’t be a “for” loop.

The second is just the stupid-way to do this problem, using additional instead. I will give two kinds of methods (one is similar to the author’s, but a bit shorter)

#include <iostream>
#include <iomanip>
using namespace std;
//
// int main()
// {
// 	int row = 10;
// 	int column = 10;
// 	int table_array[row][column];
//
// 	for (int i = 1; i < row; i++)
// 	{
// 		for (int j = 1; j < column; j++)
// 		{
// 			table_array[i][j] = i*j;
// 			cout << setw(5) << table_array[i][j];
// 		}
// 		cout << endl;
// 	}
// 	return 0;
//
//
// }

// int main()
// {
// 	int row = 13;
// 	int column = 13;
// 	int table_array[row][column];
//
// 	for (int i = 1; i < row; i++)
// 	{
// 		int temp = 0;
// 		for (int j = 1; j < column; j++)
// 		{
//
// 			temp += i;
// 			table_array[i][j] = temp;
// 			cout << setw(4) << table_array[i][j];
// 		}
// 		cout << endl;
// 	}
// 	return 0;
// }

The first method just takes the cout into the loop as well.
The second is just the stupid-way to do this problem, using additional instead.
