I need a code that says in which index the words in the first file are in the second file, how can I do it, can you give a hint(problem is number of words in the files might be more than a million)

check line constraints, set a buffer with proper size according, read the files as you please and apply the comparison. Good luck

Nope thanks the only problem is i couldnt find how to read the file which only containing words and seperated whitespaces(without storing it)

string/token comparison tasks require you to store something. I dont follow you.

hi
in this code, do-while doesn't work, I expect to see at least 3 cycle to achieve the root but it shows me only one number which is the final answer, what's the problem?

How can i create or generate a c++ project in vscode so that i can build and run as like in visual studio ide ?

Check this tutorial guy
Thanks.
But actually I got confused about the c++ project structure in visual studio ide. And also, in some GitHub projects they use to have a lot of other directories(or libraries or something i don't know) in their project structure.
So, i was thinking of that stuff. But VScode as an editor doesn't generate a project structure for you. So, i was asking if VScode too can generate/create a project structure like that ?

how i can change this algorithm to another ?
int main()
{
int size=-1;
scanf("%d", &size);
int squares[size];
for (int i = 0; i < size; i++)
{
squares[i] = (i + 1) * (i + 1);
}
int x[size * size];
int result = 0;
for (int i = 0; i < size * size; i++)
{
x[i] = -1 * (i + 1);
for (int j = 0; j < size; j++)
{
if (squares[j] == (-1) * x[i])
x[i] = -x[i];
}
result += x[i];
}
printf("%d", result);
}
why do all that when you can take a pen and paper and find the end formula

and then just smash it in C if you want

printf("%d", result);
}
if you want solution/answer then here it is:
#include <stdio.h>
int main() {
long int n;
scanf("%ld", &n);
long int sum = (n * (n + 1) * (2 * n + 1) / 3) - (n * n * (n * n + 1) / 2);
printf("sum = %ld\n", sum);
return 0;

Hello guys. Im trying to generate project with CMAKE with custom toolchain (embedded, XC8 compiler) on windows 10.
But cmake ignore custom toolchain.
It always generate files for MVS.
Im tried with -G"Unix_Makefile" and it change behavior, but i still need custom toolchain to execute.
The problem also in that is my first cmake project =)
SetPf
The quick guide says, what im only need to add:
set(CMAKE_TOOLCHAIN_FILE *path to toolchain.txt*)
set(MICROCHIP_MCU *mcu model*)
At top of CMakeLists. But in fact, im just getting default generation.
And yes, every time before generation, im clean the folder.

I would have loved to help you out but I don't use XC8, I use CCS C... more like C.

Its not problem of compiler (up to this point) but toolchain file launch.

it prints 120 and than the product of 121 and 119, but it is packed with errors.

hi,
here is the code for calculating the roots of an equation, I used a do-while loop but it doesn't work. It shows me just one root and seems that it doesn't repeat the process. I debugged it but the problem is still unsolved. what's the problem?

Luckily it isn't an issue for the c++ compiler, it's just hard to read

you can't instantiate Png unless all pure virtual functions have been implemented.

how else can i determine if a class overrides a funtion?
Anonymous
would i need like... a function pointer table thing?
olli
Why do you need to see whether a certain class overrides a function? That's against the principles of OOP and hence bad design.
Anonymous
cus i want to be able to decide what callback i should call at runtime based on class information
olli
let the class call the callback as it has (or at least should have) all the necessary information.

eg
class Plugin {
public:
virtual int write(PortUtils2 * in, PortUtils2 * out) = 0;
virtual int write(PortUtils2 * in, PortUtils2 * out, unsigned int samples) = 0;
virtual int write(PortUtils2 * in, Plugin & mixer, PortUtils2 * out) = 0;
virtual int write(PortUtils2 * in, Plugin & mixer, PortUtils2 * out, unsigned int samples) = 0;
};

or would i need to do
https://gist.github.com/a741fe8ac4b60307763f5d31b202dd69
and have classes override the appropriate functions
Anonymous
then say...
Anonymous
if (plugin.requires_sample_count()) {
if (plugin.requires_mixer()) {
return plugin.write(in, mixer, out, samples);
} else {
return plugin.write(in, out, samples);
}
} else {
if (plugin.requires_mixer()) {
return plugin.write(in, mixer, out);
} else {
return plugin.write(in, out);
}

but I think the loop isn't working, do you think that the method is calculating the root accurately?🤔

calling a subclass's functions will call any functions that are overriden right?
for example
Plugin_Type_Mixer * mixer_ = reinterpret_cast<Plugin_Type_Mixer*>(mixer);
mixer_->addPort(mixerPortA);
and
class Mixer : public Plugin_Type_Mixer {
/* override addPort */
}
