Moving Objects in Turbo C++

Expand Post »

How do you make an object, say a rectangle, move in turbo c++, using right and left arrow keys?

I want the object to move when a user presses right or left arrow keys.

Please reply ASAP either here or at my email <<email address snipped>>

Re: Moving Objects in Turbo C++

Use the nonstandard getch() to handle your keyboard input - but beware, it's not supported on all compilers and the input is non-buffered. That being said, there's no C/C++ standard for asynchronous input as far as I know, so using getch() is your best bet.

Using variables to keep track of the object's location, you can then draw it using Turbo's graphics.h file. There's more information about Turbo graphics here:

Hope this helps

Re: Moving Objects in Turbo C++

No one will write the exact code for you.

So do some reading and write it yourself.

Start with something a bit more trivial - Learn how to manipulate user input, and how to generate output first. then you'll be one step towards creating a program which combines input/output.

There is no "exact" syntax for doing what you want.. How you accomplish it is entirely up to you, although you need to learn the basics first, then you'll know what options you have available to you.

here's your solution

you can use function getkey() for getting integer for that key

C++ Syntax (Toggle Plain Text)
{
int ch;
if(kbhit())
{
      ch=getkey();
 }
 
switch(ch)
{
//for right errow key     
case 77:
// type your code here i.e. if you press the right errow key this will happen
//gotoxy(x,y)  function can help you here
 
//for left errow key     
case 75:
// type your code here 
 
//for up errow key     
case 72:
// type your code here 
 
//for down errow key     
case 80:
// type your code here 
 
}
{
int ch;
if(kbhit())
{
      ch=getkey();
 }

switch(ch)
{
//for right errow key     
case 77:
// type your code here i.e. if you press the right errow key this will happen
//gotoxy(x,y)  function can help you here

//for left errow key     
case 75:
// type your code here 

//for up errow key     
case 72:
// type your code here 

//for down errow key     
case 80:
// type your code here 

}

you can make you own program which will let you know the integer value that getkey() returns for all keys..try it yourself

if u get some error like " function getkey should have a prototype " paste goto.c attached with solution file in bin of your turbo cpp compiler.

hope this will hlp ...
