Beginner Request help w/ Assignment

My assignment to convert dates to European Date, Julian Date, Military Date, and Business date is due in 8 hours and I can't figure out how to fix the errors. Upon compiling I get these errors:

21: Undefined symbol 'GetDatemonth' in function main()
45: If statement missing ( in function GetDate(int &,int &,int &)
55: Declaration syntax error in function GetDate(int &, int &, int&)
221: Declaration missing ; in function GetDate(int &, int &, int &)
221: Compound statement missing } in function GetDate(int &, int &, int &)

Here is my code:
//program to display Eropean Date, Julian Date, Military Date, and Business date formats.

#include <stdio.h>
#include <string.h>

#define TRUE 1
#define FALSE 0

int GetDate (int &month, int &day, int &year);
void Europe (int month, int day, int year);
void Julian (int month, int day, int year);
void Military (int month, int day, int year);
void Business (int month, int day, int year);



void main (void)
{
int month, day, year;
GetDate (month, day, year);
while (GetDatemonth > 12)
{
printf ("Data entered was invalid!\n");
printf ("Now go home and think about what you have done!\n");
break;

}
Europe (month, day, year);
Julian (month, day, year);
Military (month, day, year);
Business (month, day, year);


return;

}

int GetDate (int &month, int &day, int &year)

{
printf ("Please enter a US date format (mm/dd/yr) \n");
scanf ("%d/%d/%d" ,&month, &day, &year);
while(1)
{
if {0 < month > 13 && 0 < day > 32 && 0 < year > 100)
else
break;
printf ("Date entered = \t\t\t%d/%d/%d\n" ,month, day, year);
}
return 0;
}

[Gamble]

Let's see...

*First of all, you're referencing 'GetDatemonth' in your main function. There doesn't appear to be a variable or function with this name; I can only assume you meant to use 'month' instead.

*The second error is caused because you haven't given a statement for the 'if' portion of the if/else clause in GetDate(). Even if you don't perform any operations, you still need to add a semicolon before the else:

if {0 < month > 13 && 0 < day > 32 && 0 < year > 100)
; // Do nothing
else
break;

By the way, you can't specify Boolean conditions this way. '<' and '>' are binary operators, and you need to have exactly two operands for each. It would be nice to use statements like '0 < month > 13', but this is illegal in c/c++.
