Your code should be executed or called within main..Example

int main()
{
if (some_condition)
{

}
else if(some_other_condition)
{

}

return 0
}

You have a whole lot of code that isn't contained within main or any callable function.

#include <iostream>

bool myfunc(const char *s)//function - myfunc starts
{
	if (std::cout << s << std::endl)
	{
		return true;
	}
	else
	{
		return false;
	}
}//function - myfunc ends

unsigned long double_it(unsigned long val)//function - double_it starts
{
	return val * 2;
}//function - double_it ends

int main(void) 
{
	unsigned long ans = 0;

	myfunc("test string");//function call

	ans = double_it(123);//function call

	std::cout << ans << std::endl;

	return 0;
}

Sorry, this is my first time.

jalenamichelle 0 Newbie Poster · Answer 2 · 2010-10-28T06:18:19+00:00

my teacher gave us code to start out with and he included

int main(void);

 

void menu(void);

int getChoice(void);

 

void calendarToJulian(void);

void getCalendarDate(int *month, int *day, int *year);

 

void julianToCalendar(void);

void getJulianDate(int *day, int *year);

 

int isLeapYear(int year);

 

FILE *csis;

 

int main(void) {

    int choice;

   

    fopen_s(&csis, "csis.dat", "w");

    do {

        choice = getChoice();

        switch (choice) {

            case 1 : calendarToJulian(); break;

            case 2 : julianToCalendar(); break;

            case 3 : break;

        }

    }

    while (choice != 3);

    return 0;

}

 

int isLeapYear(int year) {

     return ((!(year % 4) && year % 100) || !(year % 400));

}

so thats how he wants us to start

Yeah, so?

What is int main(void) supposed to do?
How about void menu(void) ?
Is there a reason for int getChoice(void) ?
etc.

So start with what he wants. Figure out what the functions are supposed to do. Add code in short segments. And compile often.
