the first printf should give me a straight list of all the "i" numbersCode:#include <stdio.h> int main() { int sum=0; int i; for ( i=1;i<=1000;i++){ if ((i%3==0)||(i%5==0)){ sum=sum+i; printf("%d\n",sum); //the first printf } } printf("%d\n",sum); //this line is not being executed return 0; }
and the last printf which supposed to give me the total sum
doesnt even executes?
It does on my machine...
I modified the code to print A) on the first printf, and B) on the last one.
The output I got was:
--Code:A) 3 A) 8 A) 14 A) 23 A) 33 A) 45 A) 60 .... A) 230178 A) 231173 A) 232169 A) 233168 A) 234168 B) 234168

what software do you use??
i get only this output

That screenshot looks like the first printf isn't happening, but the second one is (since you only have one number and not four hundred and fifty or so). Of course that means that the code you compiled is not the code you posted.
when i remove the first one it shows absolutely nothing
i changed the first printf to
printf("\t%d\n",sum);
but nothing changed
maybe my software is bad
is there any free c/c++ compiler which doesnt needs sp2 or linux
??
gcc-mingw is OK and works on (or at least as far back as) Win2K, so shouldn't need any particular XP service pack - of course, I kind of like SP2, but that's a separate issue.
What compiler are you using now?

code block 8.02
it gives me that CMD screen
its realy weird
i am used to a console box
i tried to install gcc-mingw
but the files i found ends with "tar" or "gz" which are asociated with linux
???
Ok, so if you are using code::blocks, then the actual compiler is gcc-mingw 3.4.2, which shouldn't be much different from the gcc mingw 3.4.5 that I'm using here. So it should work.

you have this cmd box as output too??
i think that it because of that cmd box
even in dos command it showed only the last line
??
I use a standard command prompt "box" from Windows XP (sp2 but I'm sure that makes no difference at all as I have written many programs in Win2K with the same compiler and never had any problem with "lines missing").
What if you do "myprog > out.txt" and have a look at out.txt?

i cant use text output
i need a console box
what should i do so all the output will be presented on the cmd creen
plus when i remove the first printf it doesnt give any output
although the second output should print the total sum
???
And what exactly are you outputting to the console - hieroglyphs?Originally Posted by transgalactic2
I'm not suggesting you should do this for any other purpose than to show that the output is there.
You may also want to add "fflush(stdout)" at the end of your main function - that would flush the output to console if needed.

So you are saying that this program:plus when i remove the first printf it doesnt give any output
gives you no output (instead of 234168) when compiled and run in Code::Blocks?Code:#include <stdio.h> int main() { int sum=0; int i; for ( i=1;i<=1000;i++) { if ((i%3==0)||(i%5==0)) { sum=sum+i; /*printf("%d\n",sum);*/ /* the first printf */ } } printf("%d\n",sum); /* this line is not being executed */ return 0; }

maybe i need to change the settings of the code blocks ??
apparently if the code works fine in your software
then the problem is not with the code but with the software running it
Code:#include <stdio.h> int main() { int sum=0; int i; for ( i=1;i<=100;i++){ if ((i%3==0)||(i%5==0)){ printf("%d\n",sum); sum=sum+i; } } printf("%d\n",sum); return 0; }
