Thread: hopeless little c program

Hello,

I'm working on a project where I'll calculate a persons age using birthdate and current date supplied by user.
I can't get the age to print out as an integer.

as an additional comment I had already added if and else if statements further make the calculations depending on the date entered but had taken them out to revert back to beginning to get the print out right before moving on.

Code:

/* this program will calculate a person's age based on the current year and person's birthdate then print results.*/


#include "stdafx.h"
//function declarations

void getBirthDate(int* birthDay, int* birthMonth, int* birthYear);
void getCurrentDate(int* currentDay, int* currentMonth, int* currentYear);
int calculateAge(int currentYear,int birthYear);
void printResults(int birthYear, int birthMonth, int birthDay, int currentYear, int currentMonth, int currentDay);


int main(void)

{
	//local declarations
	int birthYear;
	int birthMonth;
	int birthDay;
	int currentDay;
	int currentMonth;
	int currentYear;
	int age;
	
//statements

	getBirthDate(&birthDay, &birthMonth, &birthYear);
	getCurrentDate(&currentDay, &currentMonth, &currentYear);
	calculateAge(birthYear,currentYear);
	printResults (birthYear, birthMonth, birthDay, currentYear, currentMonth, currentDay);
	age = calculateAge(birthYear, currentMonth);
	
	return 0;
} //main

/* ===================================getBirthDate=============================

void getBirthDate(int* birthDay, int* birthMonth, int* birthYear)

{

		//statements
	
	printf("Please Enter your birth date in  dd, mm, yyyy format: \n");
	scanf_s("%d %d %d",birthDay,birthMonth,birthYear);
		
	return ;

} //getbirthYear

/* ===================================getCurrentDate=============================

{ 

		//statements
	
	printf("Please Enter the current date in  dd, mm, yyyy format: \n");
	scanf_s("%d%d%d",currentDay,currentMonth,currentYear);
	
	
	return ;

} //getCurrentDate

/* ==================================CalculateAge=============================================

*/
int calculateAge(int currentYear, int birthYear)
{
//local declarations

int age;

//Statements

age = currentYear - birthYear;

						printf("you are %d\n");
	
 return age;

} //calculateAge

/* =======================================printResult=====================================================

void printResults(int birthYear, int birthMonth, int birthDay, int currentYear, int currentMonth, int currentDay)
{
	//local declarations


	//statements

	printf("Your birthday is %d,%d,%d\n", birthDay, birthMonth, birthYear);
	printf("The current date is %d,%d,%d\n", currentDay,currentMonth, currentYear);
	//printf("you are %d\n", age);
 
	return ;
} // printResult
