Debug errors in Turbo C program

[jocobunshin]

Hi there! I'm new in Turbo C... uhmm our teacher gave us a project to make a program in Turbo C. Im from the Philippines, and our project is due on tuesday, februrary 13, 2007... can anyone check my program? I used Turbo C ver. 2.01
And the following errors occured:
1) 51: Declaration Syntax Error
2) 149: Return statement missing ; in function Z
3) 150: Declaration Syntax Error

Here's my program below:

#include<stdio.h>
#include<conio.h>
#include<dos.h>

Thank you in advance! i hope you could help me...

In the first section, you simply start a set of brackets {} without a function header or inside main - they simply are there. I don't think this is allowed - consider including this section (and the last section) in int main() instead of in their own little sections.

In the middle section, you had forgotten a semicolon after return Y * 10 - thus, the compiler never recognized the return statement.
