First, the range specification for Plot is wrong. Plot expects three
Elements, not four. So it should be
Do[Plot[Sin[x - c], {x, 0, 4 Pi}, Ticks -> None],
{c, 0, 2 Pi - Pi/10, Pi/10}]
But this will give you no output too, because Do returns Null (nothing).
You can do the following:
Do[Print@Plot[Sin[x - c], {x, 0, 4 Pi}, Ticks -> None],
{c, 0, 2 Pi - Pi/10, Pi/10}]
or
Table[Plot[Sin[x - c], {x, 0, 4 Pi}, Ticks -> None],
{c, 0, 2 Pi - Pi/10, Pi/10}]
