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;
}
