QUESTION
I was reading this code (source):
...ANSWER
Answered 2021-Jun-16 at 02:16The n2 - n1
in the case of a negative number as a result when converted to bool
will yield true
. So n1
turns out to be less than n2
. That's why it is a bad practice to use int
s in such Boolean context.
Yes, as stated in the documentation:
...comparison function object which returns true if the first argument is less than the second
But the implementation of the comparison here leads to failure. Try this and see for yourself:
QUESTION
I'm learning C++ and have come to a bit of a halt. I'm trying to iterate over a vector with a range-based for loop and update a property on each of the objects that belong to it. The loop is inside of an update function. The first time it fires, it works fine; I can see the property gets updated on each member of the vector. However, the next time the for loop is initiated, it's still updating the original data, as if the previous run did not actually update the source values. Is my range declaration configured correctly? Pointers are still a bit of a mystery to me. In general I'd be very thankful for any help!
...ANSWER
Answered 2021-Jun-15 at 23:19Vector3 position = point.position;
makes a copy of point.position
. The following code then updates this copy, which in turn is thrown away when it goes out of scope at the end of the if
statement.
The solution is simple enough - use a reference instead: Vector3 &position = point.position;
. The rest of the code can be left as-is.
QUESTION
int i = i;
int main() {
int a = a;
return 0;
}
...ANSWER
Answered 2021-Jun-15 at 02:44Surprisingly, this is not undefined behavior.
Static initialization [basic.start.static]
Constant initialization is performed if a variable or temporary object with static or thread storage duration is constant-initialized. If constant initialization is not performed, a variable with static storage duration or thread storage duration is zero-initialized. Together, zero-initialization and constant initialization are called static initialization; all other initialization is dynamic initialization. All static initialization strongly happens before any dynamic initialization.
Important parts bold-faced. "Static initialization" includes global variable initialization, "static storage duration" includes global variables, and the above clause is applicable here:

I'm working on an algo dealing with a multi-dimensional array. If there is a zero, then the elements of the same column, but following arrays will also equal zero. I want to be able to sum the items that are not zeroed out.

Ansible 2.11.0
I have a shell script that accepts 2 parameters that I want to run on a Windows host, but want to run it inside git-bash.exe

Answered 2021-Jun-15 at 17:47be aware I don't have a Windows machine against which to try this, so it's just "best effort"
As best I can tell, your problem is because you are trying to recreate the behavior of win_shell
by "manually" invoking that improperly quoted cmd.exe /c
business, ending up with cmd.exe /c "cmd.exe /c whatever"
; dialing up the ansible verbosity -vv
could confirm or deny that pattern
Also, the win_shell
docs say to use win_command:
unless you have a shell redirect need, which as written your task does not.

Answered 2021-Jun-15 at 17:11You could use the split() command in Python to break up your sting into a list. You can then iterate over the elements inside the list. You could do this al follows:

I have the data.table dt
to which I want to add a new column new_col
only when all elements in the group are zero.
ANSWER
Answered 2021-Jun-15 at 17:16Here, we can use if/else
as ifelse
requires all arguments to be same length all(a == 0)
is of length 1, along with the 'yes' but 'no' is not of length 1, which leads to recycling
QUESTION
I am aware that floating-point numbers are tricky. But today I encountered a case that I cannot explain (and cannot reproduce using a standalone C++ code).
The code within a large project looks like this:
...ANSWER
Answered 2021-Jun-15 at 09:57Barring the undefined behavior which can be easily be fixed, you're seeing the effect of denormal numbers. They're extremely slow (see Why does changing 0.1f to 0 slow down performance by 10x?) so in modern FPUs there are usually denormals-are-zero (DAZ) and flush-to-zero (FTZ) flags to control the denormal behavior. When DAZ is set the denormals will compare equal to zero which is what you observed
Currently you'll need platform-specific code to disable it. Here's how it's done in x86:

QUESTION
I am crunching large amounts of data without a hitch until I added more data. The results are written to file as strings, but I received this error message and I am unable to find programming error after combing my codes for 2 days; my codes have been working fine before new data were added.
...ANSWER
Answered 2021-Jun-15 at 07:04First of all: a Rat
with a denominator of 0
is a perfectly legal Rational value. So creating a Rat
with a 0 denominator will not throw an exception on creation.
I see two issues really:
- how do you represent a
Rat
with a denominator of0
as a string? - how do you want your program to react to such a
Rat
?
When you represent a Rat
s as a string, there is a good chance you will lose precision:
