Help with c++

I made a program called "conversion" (don''t flame me for going to gamedev.net, i''ll be in game programming soon) but how come when I run the program, it converts (fahrenheit to celcius) then the window closes automatically w/o me seeing if it worked correctly. Here''s my code: // // Program to convert temperature from Celcius degree // units into Fahrenheit degree units // Fahrenheit = Celcius * (212 - 32)/100 +32 // #include #include int main(int nNumberofArgs, char* pszArgs[]) { // enter the temperature in Celcius:"; int celcius; cout << "Enter the temperature in Celcius:"; cin >> celcius; // calculate conversion factor for celcius // to Fahrenheit int factor; factor = 212 - 32; // use conversion factor to convert Celcius // into Fahrenheit values int fahrenheit; fahrenheit; fahrenheit = factor * celcius/100 + 32; //output the results cout << "Fahrenheit value is:"; cout << fahrenheit; return 0; }

cant you just at the end before "return 0" put

cin >> celcius

obvious not gona make use of the value, but just so that it waits for you to press enter

Very bad idea to even try to accept an input when all you want it to do is pause till you press a key. If you add cin >> celcius it will keep trying to accepting an input till explicitly give it one, enter key won''t work. getch() and getchar() however will accept the enter key. system("PAUSE"); is fine too, but I prefer to keep away from system(char *); command.
