Quick question, what do i want to put in the while of my do while statement in myprintitle function so that will loop around with the main part as well.
include<iostream>
#include<iomanip>
using namespace std;
int startDay(int , int );
int calcjan1(int, int );
void printMonth (int , int );
int days(int ,int , int );
int daysinmonth(int , int );
void printtitle(int , int );
int monthnum;
int main()
{
int jan=0;
char y;
char again;
int year=0;
int month = 1;
int monthnum = 1;
do
{
cout<<"Enter a year for a calendar you would like to view:";
cin>>year;
int startDay = calcjan1(year, jan);
for(month = 1;month<= 12; month++,monthnum++)
{
int days = daysinmonth( month,year);
printtitle(monthnum,year);
printMonth(startDay,days);
startDay = (startDay + days)%7;
}
cout<<"Would you like to enter another year?: Hit y to continue";
cin>>again;
system("Pause");
}while (again=='y');
return 0;
}
//====================calcjan1===================
//calculates the first day of Jan. for year entered
int calcjan1(int year, int jan)
{
jan = ((year-1)*365+((year-1)/4)-((year-1)/100)+(((year-1)/400))+1)%7;
return jan;
}//calcjan1
//===============printMonth==============
void printMonth (int startDay, int days)
{
cout<<"Sun Mon Tue Wed Thu Fri Sat\n";
cout<<"--- --- --- --- --- --- ---\n";
for(int skipDay = 0;skipDay < startDay; skipDay++)
cout<<" ";
int weekDay = startDay;
for (int dayCount =1; dayCount <=days; dayCount++)
{
if (weekDay>6)
{
cout<<endl;
weekDay =1;
}
else
weekDay++;
cout<<setw(3) <<dayCount<<" ";
}
cout<<"\n--- --- --- --- --- --- ---\n";
return;
}
//===================printtitle==================
//print the month name & year
void printtitle(int monthnum,int year)
{
do
{
int month= monthnum;
switch(monthnum)
{
case 1: cout<<"January"<<setw(20)<<year<<endl;
break;
case 2: cout<<"February"<<setw(19)<<year<<endl;
break;
case 3: cout<<"March"<<setw(22)<<year<<endl;
break;
case 4: cout<<"April"<<setw(22)<<year<<endl;
break;
case 5: cout<<"May"<<setw(24)<<year<<endl;
break;
case 6: cout<<"June"<<setw(23)<<year<<endl;
break;
case 7: cout<<"July"<<setw(23)<<year<<endl;
break;
case 8: cout<<"August"<<setw(21)<<year<<endl;
break;
case 9: cout<<"September"<<setw(18)<<year<<endl;
break;
case 10: cout<<"October"<<setw(20)<<year<<endl;
break;
case 11: cout<<"November"<<setw(19)<<year<<endl;
break;
case 12: cout<<"December"<<setw(19)<<year<<endl;
break;
}
}while(); <RIGHT HERE
return;
}//printtitle
//========================daysinmonth===================
//checks for leap year
int daysinmonth(int month,int year)
{
switch(month)
{
case 4:case 6:case 9:case 11: return 30;
break;
case 1:case 3:case 5:case 7:case 8:case 10:case 12: return 31;
break;
case 2: if((!(year % 4) && (year % 100) || !(year % 400)))
return 28;
else
return 29;
break;
}
return 0;
}//daysinmonth

what is the purpose of that do loop? Why not just remove it ? And you don't need that switch statement if you put the month names in an array of strings.
char *months[] = { "", "January","February", ... "December"}
cout<< months[monthnum] <<setw(20)<<year<<endl; Last edited by Ancient Dragon : Nov 3rd, 2006 at 11:29 pm.

I didnt ask you to write this program, I wrote it.And i thought i used the code tag because i highlighted the text and hit the code text button, which is what i was told to do. the loop is needed so it will print all those titles again if someone wanted to enter another year again after the first time. otherwise it just prints the dates. I was just wondering if anybody new what could be used to loop printtitle with the main

you don't have to do anything. When printtitle() function returns the loop in main will take care of everything. The do loop in printtitle() is not needed.

I was only being defensive because I didnt realize that was your signature. It said and i didnt realize that was your signature. And if you run the program once and then tell it to go again it wont print those titles like it does the first time.
