can't use double/float left of %?

Just tell me if I am correct that this doesn't work

Code:

#include <iostream>
using namespace std;

int main(void) {
	float diameter = 7.62;
	float length = 39;
	short int remainder = height % 100;
	cout << "The remainder is " << remainder << endl;
	
	return 0;
}

Just tell me that this code doesn't work and that I am an idiot for trying. Seriously. I mean it.

you're an idiot for trying.
where the hell did you get height from?

well of course it's not going to work, height is an undeclared identifier

>Just tell me that this code doesn't work and that I am an idiot for trying.
The code doesn't work, but you're certainly not an idiot for trying. The problem is that height doesn't exist as you haven't declared it, but there are a few other points worth making:

>float diameter = 7.62;
This should cause a warning on most compilers. Usually something about double being truncated to float. All floating-point literals are double by default, so to remove that warning you should tell the compiler that you want a float.

float diameter = 7.62f;

>float length = 39;
Same thing, different warning. Only the most pernickety compilers will warn against this, but if you are placing the value in a float you should make it a float. As it is the literal is treated as an integer.

float length = 39.0f;

>short int remainder = height % 100;
Be sure to remember that the % operator will only work on integral types, so you will get errors if you try and use it with floats or doubles. If the left operand is a floating-point value, you will probably need to cast it to int first.

yes height wasn't declared, you knew what I meant

Prelude should write a compiler, she is a programming goddess

sorry for being a little blunt there... i honestly thought you were joking.

btw, fmod() should do the floating point equivalent of %.

Who do you think writes MS's Visual Studio?

Ouch.

dont but it untill your real into c++ and bielive that youll be programming c++ for a long time. newbies should look at freewware compilers
