Very basic C++ I need help D:

First and foremost, I do not know anything about C++. I am currently trying to learn it so please go very easy on me.

My script is taking two fractions which the user defines, then it takes the fractions and makes them into decimals.

Here's what I have:

Code:

---

#include <iostream>


using namespace std;


int main ()
{
    int num1, num2, denom1, denom2, dec1, dec2 ;
   


        cout << "Please enter first numerator: " ;
        cin >> num1 ;
        cout << "Please enter first denominator: " ;
        cin >> denom1 ;
        cout << "Please enter second numerator: " ;
        cin >> num2 ;
        cout << "Please enter second denominator: " ;
        cin >> denom2 ;


        dec1 = num1 / denom1 ;
        dec2 = num1 / denom1 ;


        cout << "Decimal of Fraction 1 & 2: " ;
        cout << dec1 ;
        cout << dec2 "/n" ;


return 0;
}

Help? And please, understand I am VERY VERY new to this.

What kind of help you need, that people will write the code for you?

Probably not, considering that he has posted his code already?

@OP, the int data type only stores integers (whole numbers). There are other data types that can be used to represent floating point numbers. ;)

So I should change int main

to

float main?

No, since that would have no effect on the variables that you are concerned with (besides being wrong in itself).

Okay, please enlighten me, I am trying to get the decimal of the two fractions, but I don't know what I'm doing wrong.

As stated before I'm really bad at this and it's a miracle I've gotten this far..

Variables. Data Types. - C++ Documentation

Read "Fundamental data types" section.

Look at "double" and "float"; if not sure which one use "double".

integer division disregards any values < 1.

e.g:

1/2 = 0.5, which, as in int, is 0
4/3 = 1.3333, as an int = 1

the process is equivalent to dividing and rounding down to the nearest whole number (integers are whole numbers, as you hopefully remember).

to retain data "after the decimal" use floating point types both in executing the division operations and in storing the result.

e.g.

Code:

---

int i=1;
int j=2;
float iOverJ = i/j; // here, iOverj = 0, since the division operation is carried out with integers

iOverJ = (float)i/j; // iOverj = 0.5, since we instructed the computer to treat i as a floating point number

---

;

the following is usually preferable:

Code:

---

float i=1;
float j=2;
float iOverJ = i/j; // iOverj = 0.5

---
