QUESTION
I have some columns titles essay 0-9, I want to iterate over them count the words and then make a new column with the number of words. so essay0 will get a column essay0_num with 5 if that is how many words it has in it.
so far i got cupid <- cupid %>% mutate(essay9_num = sapply(strsplit(essay9, " "), length))
to count the words and add a column but i don't want to do it one by one for all 10.
i tried a for loop:

to apply the same function to multiple columns:

QUESTION
I am working with multiple classes and files, so I have created this dummy code to better define my problem. I have a parent class Parent
and a child class Child
. I've separated both of these in a .h and a .cpp file
parent.h
...ANSWER
Answered 2022-Jan-11 at 11:59How do I get rid of this error?
You can solve this error by adding the default constructor in class Parent
as shown below. Also, note that you need to make the constrcutors public
.
parent.h

QUESTION
In my php page I have a row of buttons which each have some values (5 in this example). These values shall be send into a ajax script which do some calculation to values and return the result for each button without reloading the homepage. In this example the result will be
FRANK=5 (button 1)
FRANK=frank (button 2)
FRANK=48 (button 3)
FRANK=Bo (button 4)
FRANK=test (button 5)
When I press the first button I should see result 1 on the button. When I press the next button I should see result 2 on the button.
I only have one result returned on button 1 since all buttons has the same container for the return value. I need more containers for return values and I could add $i to the container: . This will give me different containers to return the result to. But how can I use $i in the javascript. My problem is also that var x in the javascript always will be the value from the first button. Again I could add $i to the id="x": id="x'.$i.'" but still I only have document.getElementById("x").value to read the x value in the javascript.
I hope that somebody help me to finish the code here.

inside your function call where this
refer to current button which is clicked .Also , you cannot use same ids
for mutliple elements instead use class
selector . So, change your php code like below:
QUESTION
I need to mock a Function (funk) call that is dependent on the return values of two other functions that is called within this Function (funk). Is it possible to use more than 1 Patch to mock the return value of the two called functions.
API to be Tested/ Mocked:
...ANSWER
Answered 2021-Nov-20 at 22:46It is legal to use multiple patches like this.
I think your issue is because you have patched a function, and are trying to compare the patched function to an integer. You set the return value in the mock, but you still need to call it to get that return value.
QUESTION
I am working on a Problem in Maple. But the question i have is general and could be answered based on ANY programming Language.
The Problem:
- Use only map function (no loops). Assume there are two lists A and B with n and m elements. replace those elements in A with "true", which are also found in B and replace the other elements in A with "false".
The question: i did try to solve this problem like that:
...ANSWER
Answered 2021-Oct-20 at 06:22It's not clear what else you may use, besides map
. Eg. your user-defined procedure uses if..then
, etc.
But the following don't use loops.
The first two are reasonably efficient in the sense that for each element t
in list A
they generate the true
as soon as any matching element is found in list B
.
In contrast the last two approaches are inefficient because they test each element t
in list A
against every element in list B
(even if a match has already been found).
QUESTION
I have a default array (genreOptions) I pass to useState in my ShuffleControls function to initialise with. I have a button that changes one array value in the stored array in the state. But when updating the state, it also causes the change of the same value in the original array which I don't want.
This is stopping my plan to also use the original array to reset state array values from a button and to possibly use it elsewhere. I have tried making a clone of the original array and passing that in.
...ANSWER
Answered 2021-Oct-10 at 00:43You're only creating a shallow copy of the array with [...genreOptions]
, so changes to the array elements result in a change to the original array. A similar example:
QUESTION
For low-level programming, sometimes it's necessary to say, at a given memory location, this is where my address is. For this post, the example is the PIR1
register in the PIC16F886 and related microcontrollers. It's always found at address 0x000C.
I've taken this approach:
...ANSWER
Answered 2021-Sep-21 at 11:23"warning 88: cast of LITERAL value to 'generic' pointer" appears to be a false positive. There is nothing wrong syntax-wise or language-wise with your macro. The C standard explicitly allows such conversions, see C17 6.3.2.3/5:
An integer may be converted to any pointer type. Except as previously specified, the result is implementation-defined, might not be correctly aligned, might not point to an entity of the referenced type, and might be a trap representation.
(Alignment & traps are of no concern in this case.)
Embedded systems compilers in general and PIC compilers in particular, have a bad reputation of non-compliance to standard C. So you either have to figure out how to disable the broken warning or consider using a different compiler.
Unrelated to the warning, you also have a severe bug, namely the missing volatile
. I would recommend to study this: How to access a hardware register from firmware?
QUESTION
First of all, sorry I'm newcomer with PHP and I have searched to learn what I am trying to do but could not find any solution. My question may seem simple to an expert developer. If it hurts any expert programmers ego, please do not close because any kind programmer can see and help me. Thanks.
I have json data from curl http request, that I change to array:
...ANSWER
Answered 2021-Sep-12 at 20:59If your array is saved in the $profile
variable then your array to display is $profile['data']
. Furthermore, using the static address [0] in the loop for this particular data structure is also wrong.
There is no additional array there. The $pro
variable in the loop is the last array in this structure, and that's where you read specific fields.
The second thing is that in my opinion you are using the $no
variable incorrectly. Probably every row in the table has the value 2 in this field, right? You should pass the initialization of this variable before the loop.
In my opinion, when mixing HTML with PHP, instead of curly braces, it is better to use foreach (something):
closed by endforeach
- it's more readable.
Try this code (I added a few comments about the $no
variable in it)
