Hi I made a temperature conversion and the code is kinda many so i want to reduce it any idea how can i do it? tnx in advance. Here's the code..
and btw what's the formula in converting rankine to kelvin i have already searched in the internet and found nothing.. lol i don't even know if my formulas area correct.Code:#include <iostream> #include <conio.h> #include <stdlib.h> using namespace std; main(){ float ctemp, ftemp, ktemp, rtemp, c, f, k, r; int ch; char con, num; do{ cout<<"1. Celsius\n" <<"2. Fahrenheit\n" <<"3. Kelvin\n"<<"4. Rankine\n"; cout<<"Choice: "; cin>> ch; system("cls"); switch(ch){ case 1: cout <<"Enter Temperature in Celsius: "; cin>> ctemp; cout<<"Convert to:?\n"; cout<<"a. Fahrenheit\n" <<"b. Kelvin\n" <<"c. Rankine\n"; cout<<"Choice: "; cin>> con; switch(con){ case 'a': f = (1.8*ctemp) + 32; cout << "Temperature in Fahrenheit = " << f << endl; break; case 'b': k = ctemp + 273.15; cout << "Temperature in Kelvin = " << k << endl; break; case 'c': r = (ctemp + 273.15) * 1.8; cout << "Temperature in Rankine = " << r << endl; break; default: cout<<"Wrong choice exiting...\n"; exit(1);break; } break; case 2: cout <<"Enter Temperature in Fahrenheit: "; cin>> ftemp; cout<<"Convert to:?\n"; cout<<"a. Celsius\n" <<"b. Kelvin\n" <<"c. Rankine\n"; cout<<"Choice: "; cin>> con; switch(con){ case 'a': c = (ftemp - 32) * 0.56; cout << "Temperature in Celsius = " << c << endl; break; case 'b': k = 273 + ((ftemp - 32.0) * (5.0/9.0)); cout << "Temperature in Kelvin = " << k << endl; break; case 'c': r = ftemp + 460; cout << "Temperature in Rankine = " << r << endl; break; default: cout<<"Wrong choice exiting...\n"; exit(1); break; } break; case 3: cout <<"Enter Temperature in Kelvin: "; cin>> ktemp; cout<<"Convert to:?\n"; cout<<"a. Celsius\n" <<"b. Fahrenheit\n" <<"c. Rankine\n"; cout<<"Choice: "; cin>> con; switch(con){ case 'a': c = ktemp - 273.15; cout << "Temperature in Celsius = " << c << endl; break; case 'b': f = ((ktemp - 273.15) * (1.8)) + 32; cout << "Temperature in Fahrenheit = " << f << endl; break; case 'c': r = ktemp * 1.8; cout << "Temperature in Rankine = " << r << endl; break; default: cout<<"Wrong choice exiting...\n"; exit(1); break; } break; case 4: cout <<"Enter Temperature in Rankine: "; cin>> rtemp; cout<<"Convert to:?\n"; cout<<"a. Celsius\n" <<"b. Fahrenheit\n" <<"c. Kelvin\n"; cout<<"Choice: "; cin>> con; switch(con){ case 'a': c = (rtemp / 1.8) - 273.15; cout << "Temperature in Celsius = " << c << endl; break; case 'b': f = rtemp - 460; cout << "Temperature in Fahrenheit = " << f << endl; break; case 'c': r = ktemp * 1.8; cout << "Temperature in Kelvin = " << r << endl; break; default: cout<<"Wrong choice exiting...\n"; exit(1); break; } } cout<<"Do you want to continue (y/n): "; cin>> num; }while(num=='y'); getch(); }
