Here is an old experiment for programming, when I still did not know
C++, (only a piece of the program, so I don't get you buried under a ton
of code). You run fine?=20
There are two lines, in red, that invert their order, the scanf is done
before its printf.=20
printf("and then choose the weight\n");//THESE TWO LINES CHANGE THE
ORDERING!!!!!=20
scanf("%d\n", &weight);=20
You see (adding two lines before)=20
___________________________________=20
| Title _0X |=20
|-----------------------------------------------|=20
| [...] |
| Choose the height. |=20
| 180 |=20
| _ |=20
|___________________________________|=20
The program asks for the height, you enter the height you want, 180, and
then you wait the next prompt for the weight, but you find there is the
cursor one line below, waiting your input...=20
___________________________________=20
| Title _0X |=20
|-----------------------------------------------|=20
| Choose the height. |=20
| 180 |=20
| 80 |=20
| And then choose the weight |=20
|___________________________________|=20
And you enter any number, then the prompt appears, and from now on all
inputs are before its prompt. When the moment arrives when the program
prints your character's statistics you see what went where. It continues
doing so till the end.=20
Copying the scanf after the printf and having two scanf only makes the
error repeat in the next pair printf/scanf=20
The best is that it happens when I compile it with borland 5.5.=20

The above style of comment is not ANSI C90 compliant.

Above you begin a comment and inside it another comment which ends at
the same line. The */ terminator terminates the first /*. So you think
you have commented all the block below while you did not!=20

} */ =20

Nope, the above */ closes nothing and is a syntax error.

So here are the bugs i discovered witg a quick pass. Bad use of
comments, and REMOVE those \n and commas from scanf(). After you do the
above, resend the fixed code.
