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=============================

void getCurrentDate(int* currentDay, int* currentMonth, int* currentYear)

{

                //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=====================================================
prints the current date, birthdate and person's age
*/
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

You have to put "age" in the print statement somewhere.

Code:

---

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

*cough*

I had done that previously but the print statement printed the address of age not the value.
updated code follows

Code:

---

// COPchapter5Assignment.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"

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(currentYear,birthYear, currentMonth, birthMonth, currentDay, birthDay);
        printResults (birthYear, birthMonth, birthDay, currentYear, currentMonth, currentDay);
       
       
        return 0;
} //main

{

        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 ;

//Statements

        if (currentMonth < birthMonth)
                age--;
                else if (currentMonth > birthMonth)
                        age = age;
                else if (currentMonth == birthMonth & currentDay < birthDay)
                        age--;
        else
                age=age;
                                                printf("you are %d\n");
       
 return age;

} //calculateAge

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

void printResults(int birthYear, int birthMonth, int birthDay, int currentYear, int currentMonth, int currentDay)

        printf("The current date is %d,%d,%d\n", currentDay,currentMonth, currentYear);
        printf("you are %d\n", age);
 
        return ;

printResults doesn't have access to age, it's out of scope

and why the hell are you saying age=age?
that's just stupid

Then you need to improve your typing skills. Note that there is no '&' in "age".

scanf_s isn't portable. Something more of Microsoft's crap. What tutorial are you reading?
