anyone wanna help me with a little C++ coding?

[Walleye]

here is my code as it exists now.

i'm writing through emacs while telneted to san marcos.

and the middle rows will not appear proper. it's like i never wrote them at all. i cant find what's causing that, what i'm doing wrong.

a few problems:

- you should calculate blank and blank1 after x and y have been entered
- when nesting loops, do not use the same variable for the loops.
- \b is backspace, if you wanna print a blank, use " "


also your code is formatted strangely...

Why are you looping through k=1->k<=blankl twice but the second time is '/b'? What is '/b'? Obviously I've forgotten all the break characters

Secondly, not to sound like a dick, but look at my code with the spacing : image

Tell me what your program does in pseudo code. That's how you should start writing the code.

Let me explain how mine does it :

To print a rectangle, we loop through each row :
If it's the first or the last row, loop for as long as the length is and print # because these two rows are just full of # for as long as the length
Else, we're in any other row, so first print one #, loop and print length-2 spaces (because there is a # at the beginning and the end), then print one more #

You try with yours and see if it works out logically.

i dont go through blank line twice. it's blank line to signify that that's the lines. at the end of each blankl running is an end line.

blank is the # of blank spaces within a line. X - 2

Ok, I see what you're trying to do with your code.

You did it like this :

For loop for first line
For loop for inbetween
For loop for last line

It looks like it could work so long as you changed "/b" to " ", you want a blank space. Try that and see if it works.

He's right. You assign the variables before they're read in so it doesn't know what they are yet. Assign blank and its variants after your cins.

[edit] Actually, they both start @ -2 since you initialized them to 0. Which is the reason why your program compiles even though they haven't technically been read-in yet. I used to do that A LOT. [/edit]

i took your suggestion too. it still didnt work

i probably placed them wrong...

 

[dighn]

post your updated code again . you can just paste here. no need for screencap.

 

[Walleye]

it wont work with height. i can get width down, but it wont go beyond 3 as a height. just a sec, i'll see if it will do less than 3.

 

[Walleye]

alright, all heights up to and including 3 work properly. 4 reverts to 3, as does anything else.

 

[Krakerjak]

int r;
int blank;
int blank1;

cout....
cin....
cout....
cin....

blank = x-2;
blank1 = y-2;

cout....

for (i = 1; i <= x; i++)
cout << "#";
cout << endl;

for (k = 1; k <= blank1; k++)
{
cout << "#";
for (r = 1; r <= blank; r++) //*** make this change too
cout << " "; //*** and this one
cout << "#";
cout << endl;
}
for (h = 1; h <= x; h++)
cout << "#";

cout << endl;
cout << endl;

}

because you are using the same variable K in 2 for loops that are working together.

i know rm is remove... but..


oh fine, i'll google it.

Unix.

It's "mv", but he seriously needs to learn how to find some answers on his own.
