set precision in 2d array

[hobey19]

i have a 2d array, and i want to make the last column of that array be a dollar amount. i have the dollar sign there, but i can't seem to set the precision to 2 like i can with a regular variable. does anyone know how to output all of the values in the last column with a decimal point? thanks in advance.

Try using the header #include

Then before the output for the dollar amount use:
cout.precision(2);
cout.setf(ios::fixed|ios::showpoint);

You may be using the same type of thing for a variable but there is no reason you can't format the output of the array the same way. I believe you are just telling it how you want it to display.

I am a newbie at this, but I just finished a problem in my homework doing this very thing.

If it helps...here is the homework I was talking about...


//Payroll Program
//Tim Devine Chapter 7 #6

#include
#include
void main (void)


{
//Declare and initialize employee number, rate,hours,wages
int empId[8]={5658845, 4520125, 7895122, 8777541, 8451277, 1302850, 7580489};
int hours[3];
float payRate[5];
float wages[6];

//for loop
for (int index=0;index<7;index++)
{
cout<<"Please enter the pay rate for employee "< cin>>payRate[index];
if (payRate[index]<6)
cout<<"OK Cheap Scate, how about paying more than $6.00/hr?\n";

cout<<"Please enter the hours this employee worked"<<": ";
cin>>hours[index];
if (hours[index]<0)
cout<<"How about using a positive number?\n";

}

//Display each employee's wages

cout.precision(2);
cout.setf(ios::fixed|ios::showpoint);
cout<<"Emplyee Number"<<" "<<"Wages"<
for (int build=0;build<7;build++)
{

wages[6]=payRate[3]*hours[3];

cout< }
