Question

my leap year function doesn't quite work:
output should be: 1700-> not leap year
2000-> leap year
1992-> leap year
need help with age function
is there anyway to get rid of yesNo() and just do all that inmain.
if you could post code so i could compare that would be greatthanks.


#include <iostream>
#include <cstdlib>
#include <iomanip>
using namespace std;


bool leapYear(int year);
void birthDate(int &year, int &day, int &month);
int age(int year, int day, int month);
char yesNo();



int main(int argc, char *argv[]){

int year, month, day;

char userchar;

do{
cout << "Leap year birthday Program" << endl <<endl;
birthDate(year, day, month);
userchar=yesNo();
cout << endl;
}
while (userchar=='Y' ||userchar=='y');




system("PAUSE");
}


bool leapYear(int year)
{
   
     if (!(year%100==0) &&(year%4==0)){
     cout << "Lucky you, born in aleapyear!" << endl;
     return true;}
   
     else if (year/400){
     cout << "Lucky you, born in aleapyear!" << endl;
     return true;}
   
     else if (year/4 && year/100){
     cout << "Sorry, you were not born ina leapyear" << endl;
     return true;}
}//end leapYear function

void birthDate(int &year, int &day, int &month)
{
   
cout << "Please enter the year of your birth: ";
cin >> year;
cout << "Please enter the month of your birth: ";
cin >> month;
cout << "Please enter the day of your birth: ";
cin >> day;
cout << endl;

leapYear(year);
age(year, day, month);

}//end birthDate function

int age(int year, int day, int month){
    int result;
  
  
  
    return result;
}//end age function
   
char yesNo(){
char result;
bool valid=false;

while (valid==false){
       cout<<"Do you want tocontinue? (Y/y or N/n) ";
       cin>>result;
       //check to see if it isvalid..
       if ((result=='y') ||(result=='Y') || (result=='n') || (result=='N'))
         valid=true;
       else
          cout<<"You have to type a valid character.... Tryagain"<<endl;
}//end while


//sends the valid character back
return result;
}
