source of calculation error?
After compiling the source code and executing the .exe for debugging, I've found a calculation error when I try to convert celsius into fahrenheit, but I can't seem to figure out the source of it or how to fix it. Really appreciate your help, ppl. :) :)
Code:
//***************************************************************
// Temperature Conversion Program
// This program converts a Celsius temperature to its Fahrenheit
// equivalent or vice versa
//***************************************************************
#include <iostream>
#include <iomanip>
#include <math.h>
#include <stdlib.h>
using namespace std;
int main()
{
float f; // degrees farenheit
float c; // degrees celsius
char option; // type of conversion
char exit; // flag for exit
cout.setf(ios::fixed, ios::floatfield); // Set up floating
cout.setf(ios::showpoint); // pt output format
do
{
// Introduction and Prompt type of conversion
cout << "This program converts a Celsius temperature to"
<< endl << "its Fahrenheit equivalent or vice versa."
<< endl;
cout << "What type of conversion would you like to"
<< "perform? " << endl;
cout << "Enter \"c\" if you want degrees celsius" << endl;
cout << "and \"f\" if you want degrees farenheit. ";
cin >> option;
// Calculation and output
if (option == 'c')
{
cout << "Please enter the temperature in degrees";
cout << " farenheit: ";
cin >> f;
c = (5 / 9) * (f - 32);
cout << setprecision(1) << f;
cout << " farenheits equals to " << setprecision(1);
cout << c << " celsius." << endl;
} // if (option == 'c')
else
{
cout << "Please enter the temperature in degrees";
cout << " celsius: ";
cin >> c;
f = (9 / 5) * c + 32;
cout << f << " farenheits equals to " << c;
cout << " celsius." << endl;
} // else
// Prompt exit
cout << endl;
cout << "Would you like to exit the program?('y' for yes) ";
cin >> exit;
} // do
while ( exit != 'y');
system("pause");
return 0;
} // int main()
