if statement problemos

i'm trying to make a program that's menu-based that will perform addition, subtraction, multiplication, or division, but I can't get the if statement to work correctly, and i'm pretty sure i'm doing something horribly wrong. my failure of a code is attached. please help!

Code:

---

if(operation == '+' )
                    no1 + no2 == result;
                    else if(operation == '-')
                            no1 - no2 == result;
                            else if(operation == '*' )
                                    no1 * no2 == result;
                                    else if(operation == '/')
                                            no1 / no2 == result;

---

That is where your problem is...
have you read assignment?

And also, enter valid data into variables before performing operations on it :P

Code:

---

  no1 / no2 == result;

---

Backwards ... the variable holding the result always goes on the left of the assignment operator.

Wrong operator... == is a comparison ... = is an assignment.

thanks guys!

And from what I know, the variable you are changing the value of should come first, like:

a=3+4,
not
3+4=a.
