Thread: Why aren't '1' of "col 1" and "1" aligned?

Hi

I attached a screenshot from the output of the following code. Why aren't '1' of "col 1" and "1" (matrix entry) aligned? Could you please tell me the reason for this?

Code:

// read 3x4 matrix. print it, find the largest value,
// count number of zeroes;

#include <iostream>
#include <cstdlib>
#include <iomanip>

using namespace std;

int main()
{

	const int R = 3;
	const int C = 4;
	float m[R][C];
	float largest = 0;
	float smallest = 10000;
	int num_zeros = 0;
	int r, c;
	int entered_largest_r = 0, entered_largest_c = 0;
	int entered_smallest_r = 0, entered_smallest_c = 0;

	cout << "enter the matrix below\n\n";

	for ( r=0; r<R; r++ )
	{
	        for ( c=0; c<C; c++ )
	        {
	                cout << "enter entry for row #" << (r+1)
	                << " and column #" << (c+1) << ": ";
	                cin >> m[r][c];

	                if ( m[r][c] > largest)
	                {
	                     largest = m[r][c];
	                     entered_largest_r = r+1;
	                     entered_largest_c = c+1;
	                }

	                if ( m[r][c] < smallest )
	                {
	                        smallest = m[r][c];
	                        entered_smallest_r = r+1;
	                        entered_smallest_c = c+1;
	                }

	                if ( m[r][c] == 0)
	                {
	                        num_zeros = num_zeros++;
	                }
	        }

	}

	cout << "\n\n";

	cout << "entered matrix is given below\n\n";
	cout << setw(10) << "" << setw(10) << "col 1" << setw(10) << "col 2"
             << setw(10) << "col 3" << setw(10) << "col 4\n\n";

	for( r=0; r<R; r++ )
        {

                cout << "\n" << setw(10) << "row " << (r+1);

	        for( c=0; c<C; c++)
	        {
	                cout << setw(10) << m[r][c];

	        }

	}

	cout << "\n\n\n";

	cout << "largest matric element is: " << largest << ", entered at row #" << entered_largest_r
             << " and column #" << entered_largest_c << "\n\n";
        cout << "smallest matrix element is: " << smallest << ", entered at row #" << entered_smallest_r
             << " and column #" << entered_smallest_c << "\n\n";
        cout << "number of '0' matrix element(s): " << num_zeros << endl << endl;

	system("pause");
	return 0;
