Max Function
Statistical function is of many categories. One of them is a MAX function. The MAX function returns the largest value from the list of arguments passed to it. MAX function always ignores the empty cells when performing the calculation.
Power Function
A power function is a type of single-term function. Its definition states that it is a variable containing a base value raised to a constant value acting as an exponent. This variable may also have a coefficient. For instance, the area of a circle can be given as:
// SuperMarket.cpp - This
// by employees of a supermarket. The report lists total hours for
// each day of one week.
// Input: Interactive
// Output: Report.
#include <iostream>
#include <string>
using namespace std;
int main()
{
// Declare variables.
const string HEAD1 = "WEEKLY HOURS WORKED";
const string DAY_FOOTER = " Day Total ";
// Leading spaces in DAY_FOOTER are intentional.
const string SENTINEL = "done"; // Named constant for sentinel value.
double hoursWorked = 0; // Current record hours.
string dayOfWeek; // Current record day of week.
double hoursTotal = 0; // Hours total for a day.
string prevDay = ""; // Previous day of week.
bool notDone = true; // loop control
// Print two blank lines.
cout << endl << endl;
// Print heading.
cout << "\t\t\t\t\t" << HEAD1 << endl;
// Print two blank lines.
cout << endl << endl;
// Read first record
cout << "Enter day of week or done to quit: ";
cin >> dayOfWeek;
if(dayOfWeek == SENTINEL)
notDone = false;
else
{
cout << "Enter hours worked: ";
cin >> hoursWorked;
prevDay = dayOfWeek;
}
while(notDone == true)
{
// Implement control break logic here
// Include work done in the dayChange() function
}
cout << "\t\t" << DAY_FOOTER << hoursTotal << endl;
return 0;
} // End of main()
