displaying ints in price form

[mchoya]

Hello all,

I want to display a list of ints for example 100, 1000, 10000 as prices
$1.00, $10.00, $100.00.

Can I do this?

I guess I have to use the iomanip lib. But the only manipulators I know
deal with floats.

Thanks, I'll keep trying.

Oh, I have an idea, should I convert the ints into floats for display
purposes?

Is that the only way?

I would not unless you truly wish to represent
fractional quanties of money not restricted to
multiples of some unit such as the cent.

Is that the only way?

For any problem, there are usually many
solutions. This is one of the usual cases.

I would suppose so. A computer can certainly
be made to do it.

You might find it easier to just use integer division
and the modulo operator to break your quantities
into dollar and cent components, then print them
out with whatever other punctuation you like.

Thanks, I tried that. It does not display the last zero in for example 100
to $1.00.

#include <iostream>
#include <sstream>

int main(int an, char *ap[])
{
while (an-- > 1) {
std::istringstream iss(ap++[1]);
unsigned ds = 0;
iss >> ds;
unsigned dollars = ds/100;
unsigned cents = ds%100;
std::cout << '$' << dollars << '.';
std::cout.fill('0');
std::cout.width(2);
std::cout << cents << std::endl;
}
