Dividning in cpp

How do i divide in c++. I ask because my program doesnt give me the right output. I use the dev compiler ver 5 beta.
example:

Code:

---

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

using namespace std;

int main()
{
    float a;
    int x, y;
    cout<<"enter two numbers:";
    cin>>x>>y;
    ofstream file("a.txt",ios::app);
    a = x/y;
    file<<a;
}

---

I get this:
0
Is this right?

1) You need to use code tags. Place [/code] at the endof your code and [code] at the beginning. It'll put your code in a font better suited to source code, and preserve spacing.

2) You're mixing old-style headers with new one. If you need to include a standard C header, you omit the .h, and precede the name with a c. For example, "#include <cstdlib>". And, franky, you don't need that haeder anyway.

3) "wrong output" is not very descriptive at all. So that people can find the source of your problem faster, please include examples of actual output and what you were expecting.

I assume the problem is that it only provides the integer part of the division (for example, 10 / 3 = 3.0, or 1 / 2 = 0.0). The reason is that you are dividing integers, and so an integer is returned as a result. Just change the type of x and y to be float. If they must be int, then you must cast one of them to float in the division expression.

Technically, it's not that big of a deal since the headers used by the OP are all standard. Also, don't forget the <> in <cstdlib>. :)

And be carefful when y is 0 so your program doesn't crash.

thanks for the help

integer division....you can easily cast one of the variables to a float or double type and that would work too :)
