From a for loop I got the int variable i. In this example it is 1.String name = "Timer" + i;
Serial.println(i);
Serial.println(name.c_str());
Result is:

Timer

Digging further into the Arduino documentation I have found an easy but weird fix. From the website:
For example:
int sensorValue = analogRead(A0);
String stringOne = "Sensor value: ";
String stringThree = stringOne + sensorValue;
Serial.println(stringThree);
results in "Sensor Value: 402" or whatever the analogRead() result is, but
int sensorValue = analogRead(A0);
String stringThree = "Sensor value: " + sensorValue;
Serial.println(stringThree);
gives unpredictable results because stringThree never got an initial value before you started concatenating different data types.
So what I've done is:name = "Timer ";
name += i;
Might look weird but works fine.
>>54569462double average(int a, int b) {
return (a + b) / 2;
}
lmao ez kys
>>54569475
That makes sense because ""Sensor value: "" evaluates to a const char*, not a String which does overload the + operator.

You're not checking malloc's return value anywhere.
If you think that all your reasonable thing your program should do is exit if malloc fails (malloc failing is usually a sign that something is REALLY wrong), you can write your own utility function to simplify the error checking logic:void *xalloc(size_t size) {
void *ptr = malloc(size);
if (!ptr)
exit(EXIT_FAILURE);
return ptr;
}
>self->name = malloc(strlen(name) + 1);
>strcpy(self->name, name);
If you're fine with non-standard functions, use strdup, or you could implement it yourself.

This is great.
>>54571405
Go is simple, it works well in big companies because it makes adding new people to the projects easier. They can see what you are doing since the complexity of the language is very minimal.
Go can be used in a smaller company, but since you know the people well enough and you aren't bringing new people along, you can get away with using more expressive languages.

This is pretty dope. What resource are you learning to do shaders with? I need to upgrade to using opengl 3.
And how much of a performance bump should I expect in using shaders over the gl2 style texture coord VBAs?
>>54571527
there is no right answer because it's shitty ambiguous murriburger notation, you could make a case for 10 because 2(3) is written with parens instead of like 2*3 and because the spacing suggests that 2(3) is grouped on its own
>>54571580
>there is no right answer
There literally is, because pemdas (or bodmas, or whatever you'd like to call it) applies here as it does anywhere else.
>>54571552
2(3) = 2 * 3, and in the case of division and multiplication, they are done left to right.

Also wrong person to ask. I'm learning this myself entirely pretty much. I started implementing a raymarcher from this
http://graphics.cs.illinois.edu/sites/default/files/zeno.pdf on shadertoy. Moved over to GLFW and GLEW now.
I honestly don't even know what I'd consider "learning shaders". Implementing different things? Understanding reflections?
I don't even know where to go to learn how to optimize them other than the basic branching is bad and don't pass too much stuff to the GPU all the time..
>>54571616
k tard
it's clearly ambiguous, that's why it's a bait for arguments like this, the only acceptable way to write it is to write the denominator under a horizontal line or to use parens with explicit multiplication and even spacing

Why does LMC actually use characters for its machine code? As in, it uses the characters '9', '0', '2' for machine code for one instruction, rather than 902 the actual value, or better yet, 16 bits per instruction? It's pretty stupid I think, not that it actually matters

so if your function isn't explicitly a double it won't be calculated as one? I guess that makes sense.
Don't understand why it would allow you to return something other than a double though

I'm unsure whether or not _s is implementation defined, but it seemed fitting.

it does integer division, seeing as both are integers, then converts the output to a double on the return. C++ lets you return in whatever type you'd like as long as it has a defined conversion to the return value.

I also am wondering how exactly execvp works. I have the shell set to accept user input > parse it into a char array > and then fork to create a child at which point whatever comand the user input gets processed. Now I just need to implement execvp to perform functions like "ls" but I'm not sure how execvp works

i'm working on a basic simulation of predators and prey in C; but i have a conundrum
every tick each "animal" needs to update their stats
do i iterate through the animals in a function for each stat, or do i iterate through the stats in a function for each animal, which would eat less cpu time?
can't provide any code as i'm on my phone, but i can answer questions

In languages that compile to JavaScript, such as CoffeeScript, some of the retardation of JavaScript is avoidable. For instance, equality comparison in CoffeeScript, whether with == or "is" will always compile to === in JavaScript, which is type safe.
That said, no language that compiles to JavaScript can truly get rid of all of its retardation. Hopefully, web assembly will make it so better languages will be available for use on the front end without using JavaScirpt's type system.
How do I explain structs to a python "veteran"? He seems to have no concept of memory in a computer, but wants to 'grok C'
anyone know a good library for generating music in python/java? kinda interested in messing around with some music theory concepts from a programming standpoint
>>54573871
This is what you want to use. No, it's not _that_ Scala. http://www.huygens-fokker.org/scala/
>>54573866
Make him learn what memory is.
A struct is literally just a compound type that is equal to the size in bytes of all it's member variables, and C uses these byte offsets to access struct members.
This is why you cannot make a stack-allocated incomplete type, because the compiler has no idea how many bytes to allocate.

My goal for this summer is to program a web crawler and create a twitter bot that uses the crawled data. I'm going to be doing this in C++.
How hard are these goals?

Nigga web crawling is network bound. C++ is the wrong choice. Choose your favorite interpreted language.

>>54574146
It's still possible though. What would you suggest? Python?
>>54574129
The twitter bot part takes like an hour in c#.
So a summer to make the crawler seems fine.
>>54574149
Solid work, although having both 15 and 0 in your 15-cycle is redundant. I recommend editing the code and using least-absolute residuals though.
>>54574164
Do you know python? Then use it.
I use Scheme as my interpreted language but that's me.
>>54574172
I wouldn't even know how to automate posting with a bot? How exactly would that work? You would have to use twitter's API's or something.

Write it in C with libcurl. On your part, easy mode is to set a maximum traversal depth and keep a list of all destinations of a given branch for basic loop avoidance.
>>54574146
This guy is also correct though.
>>54574187
Yes you have to use twitters API.
Fortunately it is pretty straightforward to use.

you can even fuck around with downloading data into memory instead of writing to disk

it's the beginning of the "for" loop, declaring an integer i, and while i is less than 100, execute the code in the block, and perform the i++ after the block is finished.

just a toy thing i made in a few days to learn about WASM, but it was a while ago and the standard has changed a lot since then. i might put it on github after i update it to newer versions of WASM

awful, cause i put it away after a few days. i only did a tiny Scheme subset that supports nothing interesting, basically. just wanted to figure out the basics of WASM at the time.

Silly idea for a programming project: write an LLVM backend to target gbz80 (the version of the z80 ISA used on the Gameboy). Then use that to write a Gameboy game in Rust (Rust targets LLVM-IR). Bonus points: See if you can get it to run on a real Gameboy using a flash cart.
I already asked this here before but didn't get an answer.
In ruby, I have an array of objects with a starting and an ending time (intervals) and I want to check if any of the intervals overlap with some other interval. I have the code to check if they overlap, but how should I loop it?
Something along the lines of
days.each do
intervals.each do
if the intervals don't have same id and they overlap, move them to a new array
Doing this in ruby.
