about reverse date(the 1st one is a wrong question)

i want to input a date and display in this format: 08 march, 2002. and also display error massage if date is out of range. so i use function printdate().i've tried this program and haven't finished yet...so pleasee tell me the mistake and what should i do next...thank u for you attention#include<iostream.h>
#include<stdio.h>
void printdate();
int main()
{
int dd,mm,yy;
enum month {january=1;february,march,april,may,june,july,augu stus,september,october,november,december};
cout<<"input a date";
cin>>dd;
cout<<endl;
cout<<"input the day:";
cin>>mm;
cout<<endl;
cout<<"input the month:";
cin>>yy;
cout<<endl;
cout<<"input the year:";
getchar();
}
int printdate(int x, int y, int z)
{
if(mm>12)
cout<<"check the date again";
else

#include<stdio.h>
#include <iostream.h>//note addition to post.

void printdate(int, int, int); //note changes from post

int main()
{
int dd,mm = 20, yy; //note initialization of mm to an invalid value

//do you really need this?
enum month {january=1;february,march,april,may,june,july,augu
stus,september,october,november,december};

//note how request for input is now before appropriate variables
cout<<"input a date";
cin>>dd;
cout<<endl;


while(mm > 12 || mm < 1)
{
cout<<"input the number of the month with jan = 1, etc. :" << endl;
cin >> mm;
}
cout << endl;

cout << "input the year:";
cin >> yy;
cout << endl;

//note call to function, passing "valid" user input.
print(dd, mm, yy);

getchar();

return 0; //note addition to post
}


int printdate(int x, int y, int z)
{
//print out in whatever pattern you want using numbers
cout << x << '-' << y << '-' << z;
cout << y << '-' << x << '-' << z;

//make it fancier by changing numerical value for month into words
//really don't need the enum type at all for this.
switch(y)
{
case 1:
cout << "january ";
break;
case 2:
cout << "feb ";
break;
.
.
.
default:
cout << "program error. sorry." << endl;
}
cout << x << ', ' << z;

cout << "no applause please, just send money." << endl;
cout << "just kidding." << endl;
}

------------------------------------------------

if you really want to use the enum type you could do something like this:

//declare an instance of type month, just like you would any
//other type
month Month;

cout << "january, february, march, april, may, june, july, august, september, october, november, december" << endl;


cout << "type in name of month exactly as it appears in the list above" << endl;
cin >> Month;

cout << Month; //will display numeric value for Month

//one way to use Month to get written version of month displayed
switch (Month)
{
case january:
cout << "january << endl;
break;
//etc.

enum types are really integer types but given a "readable" name. I'm not sure how to validated input for enums, or what happens if user enters or programmer uses an out of range/invalid value for an enum type.
