The exponential value using c++ programming |
To calculate the exponential value of a rate over a certain time frame has always baffled me. The truth is this simple mathematical tool has not only save us some money but has been able to propagate our financial future, as bankers, investors and even politicians. I have wriiten this c++ program to demonstrate the following presentation. my intention and hope is to allow us as computer science students to grasp and develop this tool as a financial planner for all of us to come.
This program uses simple methodical approach with a top down design or what we call a modular structure of program.I would hope with this old-fashion programming scheme you will grasp the essence of it
THE EXPONENTIAL PROGRAM
//Karl Halliburton may 17,2000
//Computer Science 490 Prof Klibaner
//InterestRate.cpp Lab 2 version 2
#include<iostream.h>
#include<iomanip.h>
#include<math.h>
#include<conio.h>
// several header files were used from the library: noticable were the
// manipulator file which control the filters setiosflags and setprecision
void main()
{
float result,p,i;
int n;
float calculatedata(float ,float ,int );
// this function calculates the
// rate over a perion specified by the user
cout<<"enter value for p-->"<<endl;
cin>>p;
cout<<"enter value for n-->"<<endl;
cin>>n;
cout<<"enter value for i-->"<<endl;
cin>>i;
result= calculatedata(p,i,n );
// values that are calculated are stored
// in the variable results
cout<<"the result is "<<result<<endl;
}
float calculatedata(float p,float i,int n)
// purpose: to calculate the interest rate of a certain amount of money
//over a set period of time
// result: the rate of interest at a given period of time, this is more
//interactive between the user and the system
{
float a;
a=p*pow((1+i),n); // the assignment to which the value is stored in "a"
cout<<setiosflags(ios::fixed);// the filters that was mention earlier
cout<<setiosflags(ios::showpoint);// control the decimal point(showpoint)
//,takes away the exponential value( fixed)from the results calculated
cout<<setprecision(2);// another filter used to control the amount of
//decimal places. In this case two
return a;
// return value
}

I think that this preseentation was good;
but my reply is to the people whom are attaking C++ language by saying it is not convinient. But in fact C++ language is one of the fastest language even the new languages like java aren't fast enough. Probably the only thing which people can reproche to the C++ language is that is not portable...! Re: The exponential value using c++ programming

C++ language, many people say is powerful, but for me, it isn't a good enough for our business market. Compare with Visual Basic, even Visual C++, isn't easy enough to use it. Right now the fast growing on vaious computer language, there actually have some easy to use which can replace C++. For my self, I better kill my time to develop visual basic.

It was really great. I learned a lot from it. Re: The exponential value using c++ programming

Although I learn C++ a while, I still cannot learn most of it's function. It is hard to know all of it. And this time is talking about the exponential, it is a amazing number for me. Wherever it appears from the computer or mathematics. This program lets me know more about it. I will study it more by my lack of C++ knowledge. Re: The exponential value using c++ programming

That was interesting, and it allowed for a deeper understanding of how applications help in managing funds. Re: The exponential value using c++ programming

Wow! I really learned alot from that! Re: The exponential value using c++ programming

That was great thanks, everyone needs to learn the power of money!
