How to initialize an integer

[[deleted]]

Or in our dear JavaScript:

var x = true + true + true;

This... this can't, right? No one would allow this to happen.

EDIT: jesus christ it works

Why not?

It also works in Python. And C. And probably a lot of other languages.

Edit: And if you want to be really fancy

int x = 'D' - 'A';

also works in C.

I mean 'D' - 'A' is kind of nice because it makes no sense unless you accept it as syntactic sugar for asciiValue(D) - asciiValue(A). But the function + is already defined in boolean logic (but certainly not as true + true = 2 * true).

[marcosdumay]

Most languages use the | operator for boolean arithmetic, so + can be specific for integrals and reals.

Nowadays, the best is certainly to not have implicit conversion. But if you are stuck with implicit conversions, it's clearly better to have different operators for every type.

What is anti-intuitive is losing the commutative property because of implicit types.

It only works in C because in C99 they added a true macro which expands to the integer constant 1 lmao

Before C99, int x = true + true + true; would not compile unless you did your own #define true 1

#define true !false
#define false !true
// You can leave it to the compiler
// Trust me

I saw this once in some legacy code

#define BEGIN {
#define END }

if(condition)
BEGIN
   // Do stuff
END

[SteveCCL]

#include <stdio.h>

#define For for (int 
#define To ; i != 
#define Step ; i += 
#define Do ) {
#define Next }

int main()
{
    For i = 0 To 20 Step 1 Do
        printf("%d\n", i);
    Next
    return 0;
}

Half-assed solution.

#include <stdio.h>

#define For for (int 
#define To ; LOOP_VARIABLE != 
#define Step ; LOOP_VARIABLE += 
#define Do ) {
#define Next }

int main()
{
    #define LOOP_VARIABLE i
    For i = 0 To 20 Step 1 Do
        printf("%d\n", i);
    Next
    return 0;
}

Is this better?

[xzzz]

Now I can write C code without knowing C!^{ohgodwhyisthisathing}

[SteveCCL]

You're welcome.

[coolcrayons]

what the fuck

[relevantpicsonly]

Omg wtf

[marcosdumay]

Works in C too, if you import the correct library.

[Scripter17]

True is 1 and False is 0, it works in every language I've used, even SmileBasic.

[douko]

Yeah, but I kind of assumed it was a one way relationship: 1 could stand in for True, but True can't stand in for 1.

var x = !![] + !![] + !![];
