if, then, and gotos

Unregistered · 04-02-2002

i did alot of programming on the TI-83-86 graphin clacs and got very used to the if, then, goto style of programmin. is there anything like this in C++.
im obviously a n00b so thanks for any help.

Yes, but goto's are generally frowned apon. Instead of calling a goto, you would call a function.

example:

Code:

int add(int a. int b)
{
	return a + b;
}

int subtract(int a, int b)
{
	return a - b;
}

if (myVariable == "add")
{
	int value = add(3, 2);
} else {
	int value = subtract(3, 2);
}

Yes, they are if, else, and goto's in C++. Some simple examples would be as follows:

Code:

if( variable != 53 )
{
     // Do something here
}
else
{
     // Do this other thing instead
}

Also there is else if ( ) // for multiple if's... Goto's I believe work like this.

{   // Start of some function

     // Something
     goto EXIT;


EXIT:
     return (0);
}

I think generally goto's are considered poor programming so I never use them. I have never encountered a situation where I could not use something else to avoid a goto situation. But any other questions, just post.

Don't use goto in C++!

oh dear god, unless you are writting a bios for a piece of hardware, NEVER EVER USE GOTO...
your boss will kill you...

one entry point and exit point... thats the key....

thanks alot for all the help.
I have another question already though.
Is there a clrscn (clearscreen) type command that can be used
for programms only running in the dos prompt?
thanks again,
