The c++ faq lite is kind of like the bible to c++ programming. I'm surprised to not see it here.

Yeah =[ every time I visit this forum, I pretty much only see PHP threads, with a side of confused Flash scripters =[

This needs an update page.

Unless your gonna post that update dont bump the topic!

I use the GNU C compiler (from the GNU compiler collection). Good editors are gVim, codeblocks, and Dev Bloodshed. Vim is a general purpose editor while codeblocks and bloodshed are geared specifically for C/C++. For just fooling around with C I'd recommend codeblocks.

C++: Simple GUI

http://www.newgrounds.com/bbs/topic/1104 281

Hey C++. i've got a question with decimals. I'm just starting out with C++ and i'm trying to code a program that will calculate simple interest.

The Simple interest equation is I = PRT
I = Interest
P = Principal (starting amount)
R = Interest rate (percentage)
T = Time in years.

Interest rate has to be a decimal number when it's being calculated. For example, if I had 5.4% interest, i'd have to plug it into a calculator as 0.054.

How can I change the output to put decimal places in so I dont have to have a user input it as a decimal?

This is my code, if my previous post was unclear.

// Financial calculator

#include <iostream>
using namespace std;

int main()
{
long Interest, Principal, Time;
float Rate;

cout << "What was the principal payment?" << endl;
cin >> Principal;

cout << "What's the interest rate?" << endl;
cin >> Rate;

cout << "How many years?" << endl;
cin >> Time;

Interest = Principal * Rate * Time;

cout << "The amount of interest you'll have earned will be $"<< Interest << endl << endl;

system("PAUSE");
return 0;
}

For a test input I enter the Principal as $4500, the Rate as 9.5%, and the Time at 6 yrs. The outcome is $256500. Is there a way for me to change the output from $256500 to $2565.00?

printf ("$%.02f", value / 100.) ;

Thanks a lot!
