error: expected unqualified-id before 'switch'

[eirian]

ok so I am just learning c++, and one of the things I like to do is copy someone else's code and write it out, so I can understand what is being typed (there is a lot of googling involved. this code is supposed to do a number of options to calculate how many days old you are, other similar things with your age. its not nearly done, but I keep getting "error: expected unqualified-id before 'switch'" and "error: expected unqualified-id before '{' token ". any help would be greatly appreciated!

#include <iostream>
#include <iomanip>
#include <cstdlib>
#include <cmath>
//HOMEWORK assignment 1
//to calculate how old a person is
using namespace std;

enum MONTHS {JAN=1, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEPT, NOV, DEC};

int current_date(int current_month, int current_day, int current_year);
int days_alive(int month, int day, int year, int current_month, int current_year,
               int birth_year, int birth_month, int birth_day);
bool isLeap(int year);
int daysTilNextBday(int birth_day, int birth_month, int current_day, int current_month, int current_year, int year);
int daysInMonth(int month, int year);
int get_Birthday(int birth_month, int birth_day, int birth_year);
int daysInYear(int year);
int thisYear(int current_year);
int thisDay(int current_day);
int thisMonth(int current_month);
int bDay(int birth_day);
int bMonth(int birth_month);
int bYear (int birth_year);

char menu_choice;
char MainMenu(char shape_choice);
char Table_of_Contents();

int main()
{
    int month, day, year, current_month, current_day, current_year, birth_month, birth_year, end_month, end_day, end_year;
    char exit;

    cout << "Hello! Welcome to The Days of Our Lives Age Calculator!" << endl <<endl;
    cout << "Using your birthday, this program can perform several calculations." << endl << endl;
    cout << "Please from the following menu: " << endl << endl;
    cout << "To calculate how many days you have been alive, enter 'D'." << endl << endl;
    cout << "To calculate how many days until your birthday, enter 'N'." << endl << endl;
    cout << "To calculate how many days until you reach 4 score and 7 years, enter 'F'." << endl << endl;
    cout << "To quit this program, enter 'Q'." << endl <<endl;
    cin >> menu_choice;


    return (menu_choice);

    do
    {
        exit = MainMenu(Table_of_Contents());
    }
    while ((exit!= 'Q')&&(exit!='q'));
    system("PAUSE");
    return 0;
    }

{   //this is where it says "error: expected unqualified-id before '{' token"

char MainMenu(char menu_choice)
}

    switch(menu_choice)      //this is where it says"error: expected  unqualified-id before 'switch'"
    {
        case 'D':
        case 'd':
    }

once again this is obviously not done, it just annoys me that I cant figure out how to fix this (I was searching the internet all night last night). if you could also describe why this happened, that would be amazing!

Line 56: That { is out of place. Delete it.

Line 59: That } should be a {
