kandi X-RAY | Avara Summary
A port of the 1996 game by Juri Munkki, published by Ambrosia Software, released under MIT license. Avara is a cult-classic three-dimensional networked action FPS where you play as a remote-controlled bipedal tank. It was originally developed for Apple Macintosh with support all the way back to System 6, using the THINK C programming language. This port uses C++, SDL2, and OpenGL to replace code that relied on Macintosh system APIs, and is intended to run on Windows, macOS, and Linux. These are testing builds created with Windows 10 and macOS Catalina (10.15). If you're running an older macOS, currently you will probably need to build it yourself due to differences in the dynamically linked C++ standard library between macOS versions.

QUESTION
I'm making a simple to-do application in Javascript. The user can enter a new todo list item. I also want the user to be able to edit an existing to-do item.
So I'm trying to make a button with a onClick function to edit a span. But it keeps returning a "span is null" error.
How can I fix this?
Here is my code so far:
...ANSWER
Answered 2020-Nov-11 at 13:41You shouldn't use button.closest('span')
to select the span
element. closest()
traverses the element's ancestors, not its siblings. In your current code, edit button and span elements are within same parent node, so result of closest()
should be always null.
QUESTION
I've used strcmp
before and it worked as expected, but it's not working for me in my current code.
I'm reading a .csv
file with the names of a bunch of famous people. "Mark Zuckerberg"
is the key name that triggers things that my code will eventually do (once I get past this bump in the road and this has nothing to do with what he's been in the news for lately). I'm using a counter (queue_size
) to count the number of lines in the .csv
file. My goal is to save the value of the counter when strcmp(temp_name, key) == 0
but I'm not entering that if
statement and I can't see why.
The key appears in the .csv file as "Mark,Zuckerberg"
. I've tried using strtok
to eliminate the comma. I was successful in doing that but strcmp()
still isn't working (I adjusted the key to be "MarkZuckerberg"
). I also added memset
to clean the slate with each iteration but that didn't resolve the issue either.
Commenting the line, temp_name[strlen(temp_name) - 1] = '\0';
doesn't appear to change anything either. I know that my struct
is getting all of the names because printf
(I've since deleted) and my print_list
function prints as expected.
I really need help finding out why I'm not entering that if
statement.
Thanks in advance for any help that anyone can provide.
I think that it's something dumb that I'm overlooking but I just can't find it.
Here's my code:
...ANSWER
Answered 2018-Apr-14 at 03:29I am afraid that .csv file contains "Mark,Zuckerberg"
not Mark,Zuckerberg
.
In if(strcmp(temp_name, key) == 0){
key is compared with temp_name.
Here key is Mark,Zuckerberg
.
int strcmp(const char *s1, const char *s2);
The strcmp() and strncmp() functions return an integer greater than, equal to, or less than 0, according as the string s1 is greater than, equal to, or less than the string s2.
strcmp will return positive number if temp_name is "Mark,Zuckerberg"
because it contains additional 2 characters and, 0 if temp_name is Mark,Zuckerberg
as key here is Mark,Zuckerberg
clearly.
