John, yeah, that's the kind of error u go back to when your head's
clear & go "dugh!" Lol! I *hate* it when that happens! Send the
code & I'll see if I can figure it out. U might also wanna use text
pal or something similar, which shows u where matching braces are.
1 thing I like 2 do when I'm coding is to comment the braces, as per
the following:
main()
{/*begins main*/
int i;
unsigned int number;
for (i=0; i < 5; i++)
{/*begins for loop*/
scanf("%d",&number);
if number <= 9)
printf("single digit territory."
elif number > 9 && number < 100)
printf("double digits");
else
printf("now that's a big number");
}/*ends for loop*/
}/*ends main*/
BTW, I always put my ending brace & comments there immediately after
my beginning brace, then go up a line, press enter, & write the code.
That way the brace is filled in & u don't forget about it. It took me
a lot of years of writing code 2 figure that 1 out & it's saved me a
*bunch* of time trying 2 backtrack & figure out where I missed a
brace, or, if the program isn't behaving like I want, 2 c the logic of
where I've gone wrong w/an errant brace, which, though it may match,
is in fact in the wrong place 2 do what the program was supposed 2 do.
HTH.
