PLEASE HELP ME

hello everyone i need to draw an arrow and rotate the arrow with an angle entered by user this is my homework please help me

Homework is all about “learning to learn”, not “ask someone else to do it for me”.

Seriously.

What is your current level of knowledge? Have you managed to set-up an opengl window? Drawn something on the screen at all? If not, begin with these tutorials:
