How to show all the value(s) an int variable took in a ``for`` loop?

I have to ask the user to choose the initial value, the finale value and the incrementation in a for loop. My problem is that the c variable doesn't seem to be going up according to the i variable.

Everytime I try to run the program it only displays c=d when I cout << c; If I take out the break; it just displays c with the value d an infinite amount of time. Here's what I wrote:

int d, f, i, c;

cout << "Quelle est la valeur de depart?\n";//whats the initial value
cin >> d;
cout << "Quelle est la valeur de fin?\n";//whats the final value
cin >> f;
cout << "Quel est l'incrementation?\n";//increment?
cin >> i;

if (f > d)
{
    for (c=d; c <= f; c=c+i)
     {
        cout << c << endl;
        break;
    }//for
}//if+

else if (f < d)
{
     for (c=d; c >= f; c=c-i)
     {
         cout << c << endl;
         break;
     }//for
}//else if-
else 
{
    c = d;
    cout << c << endl;
}//else

system("pause");
return 0;

Thank you.
