pattern selection.

[666kennedy]

firstly id like to thank people for helping me with my earlier problems.
anyway, for this program im working on, i want the user to be able to select between two patterns.

eg. pattern1 makes x=1 and y=0
pattern2 makes x=0 and y=0
i tried using if statements, but it doesnt seem to work properly.

here is my code - although i wont put all of it in

cout << "please select which pattern: ";
    cin >> pattern;   
    
    if  ( pattern == '1' )
        {
            target1 = 1;
            target2 = 0;
             
        }
    
    if  ( pattern == '2' )
        {
            target1 = 0;
            target2 = 1;
             
        }
    
    cout << endl << "target 1 is: " << target1 
    << endl << "target 2 is: " << target2;

the cout commands for the targets dont show up as i would expect. there is other stuff later on that needs to be selected and done so the else command wouldnt really work.

thanks

It seems to work fine for me. Can you be more specific about how it's not working properly? Perhaps also tell us what the type of your pattern variable is?

this is a screen dump

please select which pattern: 1

target 1 is: -1.#QNAN
target 2 is: 9.79083e+027
please select each pixel in the pattern:
pixel1:

as u can see the targets dont come up as what ive set, which is a bit crap, unless im putting the numerical value in wrong. i could attach my whole code but it is very long coz im not really started making it neat and having shortcuts.

I'm guessing that pattern isn't defined like this:

char pattern;

If that's the case, then you should probably be comparing pattern against 1 and 2 rather than '1' and '2':

if ( pattern == 1 )
{
  target1 = 1;
  target2 = 0;
}
    
if ( pattern == 2 )
{
  target1 = 0;
  target2 = 1;
}

Try the else statement. I dont know but i get the correct answers when i made a few adjustments in the code.

cout << "please select which pattern: ";
    cin >> pattern;   
    
    if  ( pattern == '1' )
        {
            target1 = 1;
            target2 = 0;
             
        }
    
   else ( pattern == '2' );
          {
            target1 = 0;
            target2 = 1;
             
        }
    
    cout << endl << "target 1 is: " << target1 ;
    cout << endl << "target 2 is: " << target2;

Added:
I used target1 and target2 as integers.

oh god, that was soo trivial, i should have known better, god this is a little frustrating. anyway thanks again for ur help. no doubt ull here from me soon

[666kennedy]

it wont allow me to use ( target1 - OUTC ) as a function, why would that be?

That's a very random question. You'll need to provide a context, and preferably some code as well.
