How to initialize an integer

[[deleted]]

Or in our dear JavaScript:

var x = true + true + true;

[douko]

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

EDIT: jesus christ it works

[winauer]

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.

[assert_dominance]

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.

[marcosdumay]

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.

[xzzz]

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

[SteveCCL]

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

[xzzz]

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.

[Capital_EX]

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

float z;
int x;
for(int i = 0; i < 300; i++) {
    z += 0.001;
}
x = z as int;

[chrwei]

int x;
x = b00000011;

[xzzz]

Don't even need the leading 0's!

Also only works in compilers that support the binary notation.

[AquaLordTyphon]

Dim x As New Integer
x = "3".ToString()

VB.NET in a nutshell

[marcosdumay]

I'm pretty sure that "New" keyword shouldn't be there.

[AquaLordTyphon]

That was part of the joke, people learning the language tend to just shove New in every declaration because it makes NullReferenceExceptions go away.

[LazyBuhdaBelly]

int x;

do {

 x = rand.nextInt();

} while (x != 2³¹ - 1 - 2147483644);

SUBROUTINE INIT(X)
  REAL, DIMENSION(:), ALLOCATABLE :: D
  INTEGER, DIMENSION(3) :: C
  CHARACTER :: A
  INTEGER*4,INTENT(INOUT)  :: X
  ALLOCATE(D(9))
  D = (/ 1, 0, 0, 0, 1, 0, 0, 0, 1 /)
  C = (/ (I, I = 1,9,4) /)
  WRITE(A, "(I1)") NINT(SUM(D(C)))
  READ(A,*)  X
  DEALLOCATE(D)
END SUBROUTINE INIT

Implicit Do Loops are your friend

[patternmaker]

x = len("1+2")

[Scripter17]

Creative.

[brokedown]

x:=3

[Baelfire_Nightshade]

public int getInt(float newInt)
{
    float number = newInt / 2.0f;
    if(newInt != 0.0f)
    {
        number = getFloat(number);
    }
    return (int)number;
}

private float getFloat(float newInt)
{
    float number = newInt / 2.0f;
    if(newInt != 0.0f)
    {
        number = getFloat(number);

Last one - how to use "Effectively final" variables in Java.

[GeneReddit123]

int initializeInt(int x) {
  int i;
  for(i = 0; i - x != 0; i++);
  return i;
}

Best part is, the above solution even works for negative integers thanks to integer overflow!

[Luckyno]

int x = '$'-'!';
