What is the use of this pointer

The "this" pointer points to the actual instance. I usually use it in methods that update the instance, but need a function that returns a new instance. For example: class Test{ Test next() const{ Test ret{*this}; // This is a copy of the original // Do some work... return ret; } Test& update(){ *this = this->next(); // Here we update the original using a new instance return *this; } };

How can i declared the prime number using c++

Using function

How can i declared the prime number using c++

What? Do you mean a function that tests for primality?

What? Do you mean a function that tests for primality?

The scenario are i need to declared the number that has been given such as 2,3,5 and etc and declared it wether it is prime number or not using function

Ignoring your English quite sucks, what have you tried so far?

What is terminated and non terminated decimals??

Did you even try to look on the 'net?

This seems like a pretty simple question to google.

Yes

This seems like a pretty simple question to google.

I wanted more technical detail like when used as float n double

Then why didn't you ask that question?

Eh, whatever.

Then why didn't you ask that question?

For knowing the answer

i have a question on openMP and pipelines

i have a question on openMP and pipelines

So ask

suppose i have 4 cores and i need to execute a pipeline of 2 stages..so i give 1 thread to each stage..then how can i use the 2 more threads free to improve the efficiency?

and suppose that the 2 stages are basic..so they cannot be splitted more

I think yes

i'd like to know how

Wanted criminal

Guys someone would tell me why I take this error ?

Make it &block...

take address

Make it &block...

uhmm

Still it awares

hi guys

take address

also am I on the wrong way to getting values to put them in struct

also am I on the wrong way to getting values to put them in struct

i see some problem in your source code, first : variable block has not been declared, you just define block struct type

second : block1, block2, block3 is pointer, you should use -> instead of .

I come over this error but why the 94th code line doesnt work and returns with 96 ?

I got this problem but a new problem begins :D

how can I get 11th line's values or something else ? Anyone would tell me ?

How on Earth can I get current date and time as string?

How on Earth can I get current date and time as string?

Get the integers values of day, months, year and convert it to string That's all

With what? Chrono or ctime?

I there are static methods in std::string class iirc

Or boos is better idea?

I there are static methods in std::string class iirc

That converts to string

You don't have to overkill it

What library do you use to get those dates and time

Tried all of them.

simple task became too complicated

for small program)

i dont need complete solution... just point to right direction

Do you know how to get time and date from whatever it's in an integer representation?

Lol

i have time_t obj. And my main idea is to append current date and time to file name. to do that i need time in string format

Thank you all.

You're welcome

But what to do with error C4996: 'localtime': This function or variable may be unsafe. I know that i can use pragma to disable this.... but..

it is recommended to use %hd; however according to default argument promotion when using a function with variable length arguments like printf, it is safe to use %d

sometime you might use same format string in printf and scanf

I Have a question what does mean inline asm here void help() { asm("jmp rsp"); } int main(int argc, char **argv) { char buffer[16]; fgets(buffer, 200, stdin); return 0; }

Unconditional jump to 64 bit stack pointer

But the proc is never called

lol

I Have a question what does mean inline asm here void help() { asm("jmp rsp"); } int main(int argc, char **argv) { char buffer[16]; fgets(buffer, 200, stdin); return 0; }

Tbh, it does nothing

Unconditional jump to 64 bit stack pointer

I know it , but what exactly does it? adds gadgets to the binary?

It allows to write inline assembly which is sometimes good for optimizations

But in the most cases the compiler does it better

In this case it jumps to rsp

Aka it sets the instruction pointer to the value at the top of the stack

Which better is a valid address

It is very unsafe to do that - jumps to labels are safer

I see thanks. so basically . if I adds __asm{jmp esp} , it will generate jmp esp gadgets for the binary itself right
