function not returning the correct value
Posted on

I have a program that needs to return a value from a function. I have an output statement inside the function just to see what the output is, and it sems to work. However, upon returning the function value, it seems to always return false. It is a Boolean function. Can someone at least point me out to where I might look to understand what I am doing wrong?

system ("pause");
return 0;// Exit the main function

}//End LeapYear
//Begin day calculate function

if (testMonth >= 2)
switch (isLeap)
{
case 0: totalDay = totalDay + 28;
break;
case 1: totalDay = totalDay + 29;
}
if (testMonth >= 3) totalDay = totalDay + 31;
if (testMonth >= 4) totalDay = totalDay + 30;
if (testMonth >= 5) totalDay = totalDay + 31;
if (testMonth >= 6) totalDay = totalDay + 30;
if (testMonth >= 7) totalDay = totalDay + 31;
if (testMonth >= 8) totalDay = totalDay + 31;
if (testMonth >= 9) totalDay = totalDay + 30;
if (testMonth >= 10) totalDay = totalDay + 31;
if (testMonth >= 11) totalDay = totalDay + 30;
if (testMonth >= 12) totalDay = totalDay + 31;
return totalDay;
}//End day
I would appreciate it very much.
