I got two error saying "Error 2 error C2064: term does not evaluate to a
function taking 2 arguments" from the code below. I don't understand why or
what is wrong. Can anyone tell me what I did wrong. I am to C++. Thanks

int NumberOfEmployee (void);

int DaysOut(int);

int AverageDaysOut(int, int);

// variable declarations

//float AverageDaysOut;

void main()

{ int NumberOfEmployee, TotalDaysOut;

int AverageDaysOut;

//cout<<setprecision(2);

year? : ";

You're in serious need of some good books and/or
paying attention in class. :)

#include <iostream>
#include <ostream>

using namespace std;

int NumberOfEmployee (void);
int DaysOut(int);
double AverageDaysOut(int, int);

int main()
{
int NumOfEmployee(0);
int TotalDaysOut(0);
double AvgDaysOut(0);

NumOfEmployee = NumberOfEmployee();
TotalDaysOut = DaysOut(NumOfEmployee);
AvgDaysOut = AverageDaysOut(NumOfEmployee, TotalDaysOut);

cout << "The number of Employee in your company is "
<< NumOfEmployee << endl;

cout << "The total number of days all of "
"your company's employee missed is "
<< TotalDaysOut << endl;

cout << "The average days missed for each employee is "
<< AvgDaysOut << endl;

return 0;
}

int NumberOfEmployee (void)
{
int NumOfEmployee(0);

cout << "How many employees does your company has?: ";
cin >> NumOfEmployee;

while (NumOfEmployee < 1)
{
cout << "Enter the number of employees greater 1: ";
cin >> NumOfEmployee;
}

return NumOfEmployee;
}

int DaysOut(int NumOfEmployee)
{
int TotalDaysOut(0);
int daysOut(0);

for (int count = 1; count <= NumOfEmployee; count++)
{
cout << "How many days did employee " << count
<< " missed work during the past year? : ";

cin >> daysOut;

while(daysOut < 0)
{
cout << "Enter a positive days out: ";
cin >> daysOut;
}

TotalDaysOut += daysOut;

}

return TotalDaysOut;
}

double AverageDaysOut(int NumOfEmployee, int TotalDaysOut)
{
return static_cast<double>(TotalDaysOut) / NumOfEmployee;
}

I got a pretty bad professor and a pretty old book. I got one more
question. I need to create a function which prompt user to enter any
particular month in the year such as January, March or ect. I need to
validate the Month entered. If the user entered Match instead of March, I
need to print out a message telling the user to try again. So far, I can
think of a way to do this. Can you guys me a method and I will try to write
the code. Here is how i do it so far. Thanks.

#include <iostream>

#include <iomanip>

#include <string>

#include <stdlib.h>

using namespace std;

// function phototype

char GetMonth (void);

int main()

{



GetMonth();

}

char GetMonth(void)

{

cout<<"What month do you need to calculate customer usage charge? :";

cin>>Month;

// validation of month go here, but I cannot find a method

return Month[12];

int NumOfEmployee(0);
int TotalDaysOut(0);
double AvgDaysOut(0);
Why do you the 0 inside the parenthesis and why is the parenthesis there? I
don't get this point. please help. My book does not do anything like that.

the code was not correct here is the correct one for the month function:

#include <iostream>

#include <iomanip>

#include <string>


using namespace std;

// function phototype
char GetMonth (void);
// variable declaration
char Choice ,Month[12];

char January[12]="January",
February[12]="February",March[12]="March",April[12]="April";

char
May[12]="May",June[12]="June",July[12]="July",August[12]="August",September[12]="September";

char October[12]="October", November[12]="November",December[12]="December";


int main()

{



GetMonth();

}

char GetMonth(void)

{

cout<<"What month do you need to calculate customer usage charge? :";

cin>>Month;

// validation of month go here, but I cannot find a method

return Month[12];
}

Your code is so ugly, I dont even feel like looking into it.

The code
int i(0);
initializes the integer i with zero, i.e., the constructor of the class
int is called. For integral types like "int" or "double", this syntax
should essentially be equivalent with
int i=0;
The point is that, using the syntax "C c(x);", where C is a class and x
an instance of C, one usually saves one default constructor call. This
is due to the fact that in "C c = x;", the object c is initialized first
with its default constructor, and after that the corresponding
=-operator is called. However, a quantitative benefit will only show up
when more complicated classes C than integral types are used.

// variable declaration
char Choice ,Month[12];

char January[12]="January",
February[12]="February",March[12]="March",April[12]="April";

char
May[12]="May",June[12]="June",July[12]="July",August[12]="August",
September[12]="September";

char October[12]="October", November[12]="November",December[12]="December";

Having all the month names exactly 12 characters long doesn't really make
sense. But having said that, you probably don't want separate arrays for
each month name anyway. Make Month an array of characters strings; then
you can index into it to get the month name.

const char* Month[] =
{
"January",
"February",
"March",
// Add the rest of the month names here...
};
