Help!!! Simple Menu Program

[ghofigjong]

Anyone pls help me, i'm just learning C and my professor gave me a project. To make a simple Menu using only stdio.h, How do I input the Arrow Keys? Please Help

[orbitz]

Are you sure they wanted you to make a menu you use arrows with?? Wouldn't a simple:

1. Option one
2. Option two
3. Option three

Choice>

Work?

My professor said I should use Arrow keys like this:

(The All Caps for example is the higlighted option)
OPTION1 option2 option3

when i press right option2 will be highlighted using cprintf and so on which ever choice i have selected till I press enter.

option1 OPTION2 option3

I think it has to do with ASCII codes or something

You could find the ascii value for the arrow keys, then have a variable for storing which one is highlighted (choice), and re-print the choices each time you push the arrow keys, with the right choice being highlighted.

main
{
int choice=1, buff;

printf("CHOICE 1  choice 2  choice 3");
for(buff=getch()!='ENTER')
{
  if(buff=='LEFT ARROW')
  choice++
}

with that as a small example. Then for choice==1 print "choice 1 CHOICE 2 choice 3" etc.

Draco, I sure hope that's pseudo code
>>for(buff=getch()!='ENTER')
eh?

Also, getch() is still non-standard C.

[Draco]

yes, it is pseudo code. I'm a believer in tutoring others, not doing all the work for them.

Thanks for all the help:
Here's what i've done

{
s1();d1();c=0;
while(a!='\r')
	{
	a=getch();
	if(a==77)    /*ASCII code for right arrow*/
		c++;
	if(a==75)   /*ASCII code for left arrow*/
		c--;
	if(c>3||c<-3)
		{c=0;}
	if(c==1||c==-3)
		{mc=2;s2();d2();}
	if(c==2||c==-2)
		{mc=3;s3();d3();}
	if(c==3||c==-1)
		{mc=4;s4();d4();}
	if(c==0)
		{mc=1;s1();d1();}
	}
if(mc==1)
	{pro1();}
if(mc==2)
	{pro2();}
if(mc==3)
	{pro3();}
if(mc==4)
	{pro4();}

/*s1,s2,s3,s4 are functions that uses cprintf to display the selected menu */

Thanks again for all the help
