how do i make the c program run a function as soon as a button is pressed. for example, "Press any key when ready" how do i make that work without pressing an enter key ? i use inkey$ in Qbasic.. i dont know how i do this in c

If you're talking about a console app, then you just need to use getch()... printf("Press any key to continue..."); getch(); //rest of code will run after //a key is pressed In VC, it's defined as _getch(). Unlike getchar(), it won't make the key's character visible, if it could be.

Jeff is, of course, correct. Also, if you need the keyboard or other events to be visible during the waiting for a keypress (i.e. special function keys or mouse clicks) then use the KeyPressed function which returnes a boolean value as true when the keyboard buffer has data and false when the keyboard buffer is empty. This function does this WITHOUT extracting bytes from the keyboard buffer. This way, you can have the key test routine in a loop that can also still check for special events (for example with a case statement block) that may occur while your are waiting for any other key press to continue. borelli33

try using the kbhit(); function suppose your function is abc(); try if(kbhit()) { abc(); }
