[QUOTE="Vaxius, post: 2554881"]
After trying to compile the following code, gcc gives me

error: 'setwidth' was not declared in this scope

I'm not sure why it would do this, since iomanip is included.  Am I missing
something?

code:

#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;

int checkPoint(int, int);

int main()
{
    int n, i, j, icount;

cout << "Number of possible moves for a knight on a chess board\n\n";

for (j = 1; j <= 8; j++)
    {
        for (i = 1; i <= 8; i++)
        {
            icount = checkPoint(i, j);

cout << setwidth(5) << icount;
        }
        cout << endl;
    }
}

int checkPoint(int i, int j)
{
    int icount, p, k, n, m;

icount = 0;
    p = -1;

for (k = -2; k <= 2; k++)
    {
        if (k != 0)
        {
            for (n = 1; n <= 2; n++)
            {
                p = -p;
                m = p * (3 - abs(k));

if (1 <= (i + k) && (i + k) <= 8 && 1 <= (j + m) && (j + m)
<= 8) icount++;
            }
        }
    }
    return icount;
}
