I want to make a calculator

I specific calculator working under this sort of format.

x,y & z

x = Input from user

y = x*2-z

z = x*2/10

X is an input and Y & Z are outputs generated from the input to X.

I don't know a lot about c++ but is this the right software i should be using?

before you tell me to use Excell I want to mass produce this.

 

Give me a pm of what exactly it has to do and ill write it for you.

 

You could pretty much use any language to make this.

 

Code:

#include <iostream>
using namespace std;

void calc();
float x, y, z;

int main ()
{
	cout << "Input X: ";                               //output
	cin >> x;                                          //waits for input
	
	z = x*2/10;
	y = x*2-z;                                          

	cout << "Y: " << y << endl << "Z: " << z << endl;  //displays answers
	
	system ("pause");  //Remove if you happen to be compiling this in Linux
	return 0;
}

You could do this in any language you like, the only thing is that your 'y' equation is dependent on the 'z' equation and as C++ is sequential, you need to do your 'z' function first.

Take a look at my programming help thread in my signature if you need more help.

 

I basically want it so that you enter X and automatically y&z are outputs, without the pressing of buttons etc.

 

How do you plan on checking when the input has been entered?

Could you explain the situation a bit more fully, because the practical application of this seems futile.

Although, I do have a feeling you'd be better off doing this in an alternative language. I could make a Java GUI that does this for you in literally 5 minutes if you can just explain it a bit better.

 

Basically I want this



A calculator for hosts.

works out from the wager x2 then minus the hosts keep ( 10% )

I want it to be similar to this and you add in usernames from both duelers to keep track of them. Like i said in my OP I don't know pretty much anything about programming and am not aware of which language is best.

 

Added you.

 

In case anyone is wondering, the problem was resolved.

Product is here: http://sythe.org/showthread.php?t=1231906
Note, it is in java rather than C++

 

Lol cool .

 

just use javascript for this

 

Wow that dice host thing is really cool lol

 

I'm not sure about the code for c++, but for c you could do this:

Code:

(After all the stdio.h stuff)

main(){
  float x , y , z; 
  
  printf("Please enter x\n");
  scanf("%f" , &x);
  z = x * 2/10
  y = x*2 - z
  printf("Y = %f , Z = %f" , y , z);
}

I'm pretty sure theres going to be a syntax error somewhere, i'm sorta rusty

 

There's going to be a syntax error correct, try replacing the ''x''.

 

It's very easy, you can use C Language for this calculator program

 

Said it was solved, but to be honest, the program can be written in just about any language. Not too difficult. The guy that solved it with Java was probably just more comfortable with Java.

 

dont forget the ; behind the equations haha

 

Do not use system("PAUSE"); as it's slow and OS-dependant. Replace it with cin.get(); which carries the same function but faster and doesn't depend on your operating system. Seriously, only use system when you're testing a program or messing around, not in any serious application.

Code:

#include <iostream>

using namespace std;

int main()
{
 	int loop = 0;
 	int x;
 	int y;
	int z;
 	
 	cout << "Calculator" << endl;
 	
 	while (loop !=1) {
		  cout << "Wager = ";
		  cin >> x;
		  z = (x*2)/10;
          y = (x*2)-z;
		  cout << "\nWinner receives = " << y << "." << endl;
		  cout << "You receive = " << z << ".\n" << endl;
    }
    return 0;
}

Compile + run in console. Loops after each input.

Very simply done, some things were declared when they didn't need to be. But as you seem to be incapable of creating a C++ calculator, it's marked out for you.

Result:

 

^^ That is well done.
