It would wait for you to type an input before the window closed.

TecBrain · Oct 2nd, 2004, 7:42 AM

yes but the window is closing after adding the new value of a:

cin >> a;

Ravilj · Oct 2nd, 2004, 8:17 AM

this works for me:

(Toggle Plain Text)

#include <iostream>

using namespace std;

int main()
{
	float a,b;

	cout << "Enter degrees celcius: ";
	cin >> a;	
	cout << "Degrees Fahernheit: " << (a*1.8) + 32 << endl;

	system("PAUSE");

	return 0;
}

TecBrain · Oct 2nd, 2004, 8:39 AM

yah, that works for me too.

Can i ask what is the system("PAUSE"); for.

Pat · Oct 2nd, 2004, 9:41 AM

Whatever you write in the system() parentheses is echoed as if it was typed in a DOS command prompt, so what it would do is issue the "PAUSE" command, which effectively stops it from doing whatever it's doing and displays the message

"Press any key to continue . . ."

TecBrain, try this quick remove the system("PAUSE") and run it and see what happens, just out of interest...

TecBrain · Oct 2nd, 2004, 4:58 PM

That�s why I asked, because when I moved out the:

(Toggle Plain Text)

system("PAUSE");

The output did not appear, as soon as I entered the input the Dos screen goes away. So I was wondering if that code would be allowing the output to appear.

Thanks in all cases guys, you were helpful.

I will be asking allot of question as the time passes. :unsure:

Ravilj · Oct 2nd, 2004, 5:19 PM

interesting... yeah than just use that at the end of all your windows console programs to see the output.

Ok I downloaded Dev C compiler, when you select a new console application it sets out the followign code by default:

(Toggle Plain Text)

#include <iostream>
#include <stdlib.h>

using namespace std;

int main(int argc, char *argv[])
{
 
 system("PAUSE");	
 return 0;
}

So it seems that Visual Studio adds that in for you and with dev c its left up to you to add it in.

Here's my Celsius to Fahrenheit converter written in C

(Toggle Plain Text)

#include<stdio.h>

main()
{
    float c,f;
    printf("Celsius to Fahrenheit\n\n\n");
    printf("Enter Celsius value: ");
    scanf("%f",&c);
    f=(1.8*c)+32;
    printf("\n%.0f C = %.0f F\n", c,f);
    return 0;

}
