I'm having a problem being cause by what I believe to be my getMonthValue function which is resulting in my output always being "Saturday." Can anyone give me any reason this is happening? Thanks.

```
#include <iostream>
#include <string>
using namespace std;
bool isLeapYear (int year);
int getCenturyValue (int year);
int getYearValue (int year);
int getMonthValue (int month, int year);
void getInput (int day, int month, int year);
int main()
{
int month, day, year, century, decade, weekday, leap_year, mvalue;
char ans;
string day_week;
do{
cout << " Enter month day and the year: ";
cin >> month;
cin >> day;
cin >> year;
bool isLeapYear(int year);
int getCenturyValue(int year);
int getYearValue(int year);
int getMonthValue(int month, int year);
weekday = (day + mvalue + decade + century)%7;
if (weekday == 0)
day_week = "Sunday";
else if (weekday == 1)
day_week = "Monday";
else if (weekday == 2)
day_week = "Tuesday";
else if (weekday == 3)
day_week = "Wednesday";
else if (weekday == 4)
day_week = "Thursday";
else if (weekday == 5)
day_week = "Friday";
else (weekday == 6);
day_week = "Saturday";
cout << month << "/" << day << "/" << year << " falls on a " << day_week << endl;
}while (ans == 'y' || ans == 'Y');
return 0;
}
bool isLeapYear(int year)
{
int temp1, temp2, temp3;
temp1 = year;
temp2 = year;
temp3 = year;
temp1 = year % 400;
temp2 = year % 4;
temp3 = year % 100;
if (temp1 == 0)
return (true);
else if (temp2 == 0 && temp3 > 0)
return (true);
else
return (false);
}
int getCenturyValue(int year)
{
int century, remainder;
century = year/100;
remainder = (3-(century % 4));
remainder = remainder * 2;
return (remainder);
}
int getYearValue(int year)
{
int decade;
decade = year%100;
decade = (decade/4) + decade;
return (decade);
}
int getMonthValue(int month, int year)
{
int month
if (month == 1){
if (isLeapYear(year))
month = 6;
return (month);
else
month = 0;
return (month);}
else if (month == 2){
if (isLeapYear(year))
month = 2;
else
month = 3;
return (month);}
else if (month == 10){
month = 0;
return (month);}
else if (month == 3 || month == 11){
month = 3;
return (month);}
else if (month == 4 || month == 7){
month = 6;
return (month);}
else if (month == 5){
month = 1;
return (month);}
else if (month == 6){
month = 4;
return (month);}
else if (month == 8){
month = 2;
return (month);}
else (month == 9 || month == 12);{
month = 5;
return (month);}
}
```
