Okay I made a prog its for temperature conversion its still not developed yet and Im having problems
heres the code
the problem is when you go to Celsius Converter and there input alphabets then the programs start looping infinitelyCode:/* Software Name = Temperature Converter Calculator...

// Program that helps converting Temperature degrees.
// Formulas obtained from wikipedia.org.
#include <cstdlib>
#include <cctype>
#include <iostream>
using namespace std;

char Cnvrt_Temp_Option ;
cout << "\n==================== Convert Temperature =======================" << endl ;

cout << "[F] Fahrenheit Converter" << endl ;
cout << "[K] Kelvin Converter" << endl ;
cout << "[R] Rankine Converter" << endl ;
cout << "[M] Back to Main Menu." << endl ;
cout << "\n(Characters enclosed by the square brackets are the options.)" << endl ;
cout << "\nEnter your option: " ;
cin >> Cnvrt_Temp_Option ;
if ( Cnvrt_Temp_Option == 67 || Cnvrt_Temp_Option == 99 ) // 67 == C 99 == c
{
CelFunc();
}
// 70 = F and 102 = f
if ( Cnvrt_Temp_Option == 70 || Cnvrt_Temp_Option == 102 )
{
cout << "FahrFunc()" << endl ;
}
if ( Cnvrt_Temp_Option == 75 || Cnvrt_Temp_Option == 107 )

cout << "KelFunc()" << endl;
}

cout << "RankFunc()" << endl ;
}
} while (!( Cnvrt_Temp_Option == 77 || Cnvrt_Temp_Option == 109 )); // 77 == M and 109 == m

long double cKelvin = cTemp2Conv + 273.15;
long double cRankine = (cTemp2Conv + 273.15) * 1.8;
cout << "\nAnswer: " << cTemp2Conv << " Celsius in Fahnrenheit scale = " << cFahrenheit;

else {

cout << "\nPlease enter numerical values.\n";
}
cout << "\nDo you want to convert temperature again ?";
cout << "\nEnter Y for yes, N for no.";
cout << "\nEntering wrong option other than Y/N will result in getting back to \nConvert Temprature menu.";
cout << "\n[y]/[n]:";
cin >> again;
} while (again == 'y'|| again == 'Y');
}
I tried cin.good() and isdigit() for checking the input but both gave me same results
any help is really appreciated
thanks
