Answer 1

In JavaScript:

alert(111111111111111111111) // alerts 111111111111111110000

Answer 2

In java:

int x = 1 + + + + + + + + + + + + + 1;
System.out.println(x);

Outputs 2.

Answer 3

In PHP one can do:

System.out.print("hello");

Answer 4

In Python:
from __future__ import braces
#Output: SyntaxError: not a chance

Answer 5

try this in java:

try {
throw new AssertionError();
} finally {
return false;
}

Answer 6

For java:

Integer.valueOf(127) == Integer.valueOf(127); // true, same instance
Integer.valueOf(128) == Integer.valueOf(128); // false, two different instances

Answer 7

In C#, this doesn't generate a compiler warning:

public int Something
{
get { return Something; }
set { Something = value; }
}
When called, it causes your app to crash, it's a StackOverflowException.

Answer 8

The following text is a single complete comment:(java)

/* this comment /* // /** ends here: */

Answer 9

In C#, you can also have as many ; as you want

Answer 10

My favorite in Python is:

import this

Answer 11

What's interesting about this is that Python lets you override keywords. It was a typo (equals is adjacent to backspace) that I helped someone fix, which breaks the interpreter (easiest fix is reload):

aTuple=(1,2)
print=("take that"+"and that")
print(aTuple)

Error: 'str' object is not callable. (on the tuple print)

Answer 12

In python,try this:

d = {True:"Sun"}
d[1] = "Moon"
print(d)

Answer 13

in c++
you must know to swap you can do
a=a+b-(b=a);;;;
you must also know that
a+=b+z-x;
is evaluated to
a=a+b+z-x;

but
a=a+b-(b=a);
and
a+=b-(b=a);
don't yield same result.

Answer 14

Have you found something like these in python?

Answer 15

In python:

print("""""text""""")

outputs: ""text

Answer 16

for (int i=0; i<5; i++, extraAction()) {
// c, c++
}

Answer 17

Duff's Device. Sometimes considered skiddish, intended to save condition cycles, sometimes faster than a standard 'for' loop (but worse if ported badly):

https://code.sololearn.com/cT46etCvzTbO/?ref=app

Notice how 'case' jumps into the middle of the do..while; it sends 2 values, then loops and sends the next 8. One loop vs 10. Final byte is printed to prove it finishes.

Output is assumed to be a memory-mapped stream (so something would be watching the output byte change; this sample just couts the last value).

Answer 18

oh, cool.

In python :

Swap the value of 2 variables

a,b = b,a

Answer 19

In C++ :

You can override the operator ','
