function inside IF statement ignored

[dudewhatsup]

Hi all,

yesterday I spent the whole day on a problem I simply won't be able to figure out. I got an IF statement inside a while loop and the IF statement contains a function call. The function only changes coordinate values but to make sure that I didn't type something wrong in it I changed it to a simple cout statement. But the function is completely ignored for some reason. Here's what I got:

function:

void addblocksize2()
{pixelx=pixeloldx;pixely=pixeloldy;

if ((pixelx+blocksize)<iw){pixelx=pixelx+blocksize;}
else {pixelx=(blocksize/2);pixely=pixely+blocksize;}}

...
...
while loop

...

if (qq==qqmax){npixelcor[runner2]=-10000;npixelcor[runner2+1]=-10000;runner2=runner2+2;addblocksize2;cout<<"pixelx";cout<<pixelx;cout<<"\n";break;}


I also added the two couts before the function call:

...cout<<"pixelx";cout<<pixelx; addblocksize2;cout<<"pixelx";cout<<pixelx; ...

to see if there was any change in the value but it stays the same.

(again, I altered the funtion above to ... {cout << "here";} but nothing happens (no ''here'' appears in the dosbox). What am I doing wrong or should it be impossible to call a function in that if statement?

Cheers

Can you post the code in the proper format? I can't predict what happens in your while loop if you miss-out sections of the code.

HI Wazzak,

yep, it's quite long though and actually it's two while loops nested inside a for loop but I thought that this may be irrelevant as everything else works just fine. Ok, here it is:

while (true){if (qq==qqmax){break;}

if (check==1){break;}
if (gfound==1){break;}

pixeloldx=pixelx;pixeloldy=pixely;

if (check==0){calculation();comparison();}

if (check==1){break;}
if (gfound==1){break;}

pixelx=pixelx+1;

if (check==0){calculation();comparison();if (gfound==1){break;}}
if (check==1){break;}
pixely=pixely+1;

while (true){
qq=qq+2;cout <<qq;cout <<" ";cout<<gfound;cout<<"\n";
if (qq==qqmax){npixelcor[runner2]=-10000;npixelcor[runner2+1]=-10000;runner2=runner2+2;addblocksize2;cout<<"pixelx";cout<<pixelx;cout<<"\n";break;}
for (kkk=0;kkk<qq;kkk++)
{pixelx=pixelx-1;
calculation();comparison();if (gfound==1){break;}}

... then comes a lot of other for loops (like the one above this line) and then the while loops are closed. Maybe it's the qq==qqmax condition in the 1st while loop?

If the code is too big, try posting the code on Pastebin^[1]. From there, I will be able to read you code fully. Also, make sure that you select the correct language. When you've posted the code, post the link here.

please find the code in my last post :-)

edit: I have circumvented the function by simply writing it's content into the IF condition. Now it works and for me that suffices. I guess it's because of the first while loop which also contains the condition qq==qqmax. Probably it won't 'jump' to the function anymore if the condition is met. Anyway, thanks for your help!

addblocksize2( ) is a function. In your first while loop, you call addblocksize2( ) without the parentheses( you need these ).

how in the world could I overlook that ?! Thx Wazzak
