Thread: Need Help please

No one will write full code for you...show some efforts...whereever you are stuck...post it....someone will definetly help you

Well to begin with you are gonna need a function that would translate from C to F, and from C to F

and then in the main function you are gonna need to ask for the degreese and run the apropriate function.

Code:

#include<iostream>
using namespace std;
int main()
{
  float fahr; //holds user entered degrees in Fahrenheit
  float cels; //holds our calculated degrees in Celsius

  cout << "Enter degrees in Fahrenheit: ";
  cin >> fahr;                          //Get user input
  cels = (((fahr-32)/9)*5);             //Equation to convert F to C
  cout << fahr<<" degrees equals "<< cels << " degrees in Celsius"<< endl;  //Output answer
  system("PAUSE");  //Pause so you can read the answer
  return 0;    
}

I'm sorry but it was such an easy program that explaining it is longer than writing it. I couldn't help it. I commented to show him how it was done.

What if you want to go from Cels to fah?

you can create the functions:

Code:

int FC(int f)
{
return (f - 32) * 5/9
}

int CF(int c)
return (c * 9/5) +32
}

He didn't say he needed to go from Celsius to Fahrenheit, but yes you could have made the equation into a function.

Here is a little code you can try:

Code:

#include<vector>
#include<cstdlib>
#include<iomanip>
#include<iostream>
#include<windows.h>

using namespace std;

class Temp
{

public:

	void   menu();
	double f_to_c(char* fehrenheit);
	char*  get_user_input();
	void   display_answer(char* fehrenheit, double celcius);
	bool   again();

private:

	vector<char> user_input;
};

void clrscr();

int main()
{
	Temp *MyTemp;
	char *f_temp;

	do
	{
		MyTemp->menu();

		f_temp = MyTemp->get_user_input();

		MyTemp->display_answer(f_temp, MyTemp->f_to_c(f_temp));

	}while(MyTemp->again());

return EXIT_SUCCESS;
}


void Temp::menu()
{
	clrscr();	

	cout	<< endl << endl << endl << endl	
			<< setw(40) << "+----------------------------+\n"
			<< setw(40) << "| +------------------------+ |\n" 
			<< setw(40) << "| |                        | |\n" 
			<< setw(40) << "| | Fehrenheit  to Celcius | |\n"
			<< setw(40) << "| |                        | |\n" 
			<< setw(40) << "| | Temperature Converter  | |\n"
			<< setw(40) << "| |                        | |\n"
			<< setw(40) << "| +------------------------+ |\n"
			<< setw(40) << "+----------------------------+\n";
}



char* Temp::get_user_input()
{
	char input, *f_temp;

	cout	<< endl << endl
			<< setw(20) << "Enter temperature in degrees fehrenheit :  ";

	cin.get(input);
	
		while(input!='\n')
		{			
			user_input.push_back(input);
			cin.get(input);
		}

	f_temp = new char[user_input.size()];

	for(int i=0, back=user_input.size(); i<back; i++)

		f_temp[i] = user_input[i];

	return f_temp;
}


double Temp::f_to_c(char* f_temp)
{
	double f;

	f = static_cast<double>(atof(f_temp));

	return(((f-32)/9)*5);
}


void Temp::display_answer(char* fehrenheit, double celcius)
{
	cout << endl << endl; 

	cout << static_cast<double>(atof(fehrenheit)) << "F equals " << celcius << " degrees celcius.";
}


void clrscr()
{
    COORD coordScreen = { 0, 0 };
    DWORD cCharsWritten;
    CONSOLE_SCREEN_BUFFER_INFO  csbi;
    DWORD dwConSize;
    HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

    GetConsoleScreenBufferInfo(hConsole, &csbi);

    dwConSize = csbi.dwSize.X * csbi.dwSize.Y;

    FillConsoleOutputCharacter(hConsole, TEXT(' '),dwConSize, coordScreen, &cCharsWritten);

    GetConsoleScreenBufferInfo(hConsole, &csbi);

    FillConsoleOutputAttribute(hConsole, csbi.wAttributes, dwConSize, coordScreen, &cCharsWritten);

    SetConsoleCursorPosition(hConsole, coordScreen);
}

{

	cout << "\n\nWould ye' like to try again?";	

	cin.get(choice);

	switch(toupper(choice))

			      return false;

			      again();
