Boost is for tasks like multithreading and image processing, I just want to calculate Fibonacci for large n😅

how exactly should I use "\a" escape sequence to get a Alert in output ? In a printf statement
Daniele
printf("\a");
Daniele
what do you mean?
Daniele
boh windows and linux support that escape sequences
sree nandhan
I used \a in printf like you have mentioned , but I don't hear any alert
sree nandhan
I don't know what I should I be doing apart from using \a to make it work .

You might want to put it in a loop and make sure the speakers are on:
for (;;)
printf("\a");

Or just go hardcore and make a driver for the PIT that only writes to channel 2

In this course is there every thing about C
No, C is too complex and it's unlikely that you need to know everything about it. You can also read the standard draft here http://www.iso-9899.info/n1570.html

Compiling is fine on a c++14 compiler. My problem is that I can't think of a use case where people write code like this.

Good Morningorning Everyone

It's working.

I would suggest to get rid of the bind, otherwise it's fine
olli
in this case you can just pass func2
Entity entity(func2);

Hello

Hello, i create a C++ server to get files from a Python script. When i send the size of the file, It get me a error than crash the program, may anyone say me why this happend?
V01D
Hard to say without any error message
V01D
Also, what code failed? The server or the client
Pablo humano
Pablo humano
Okey sry
Pablo humano
Also, what code failed? The server or the client
the server code failed, but the error appear in the cliente code
Pablo humano
but the error appear because I send the size of a file from a client (3640214590) and the server receive that 3640214590�OV, and when I try to convert to a double it crash
V01D
Does it work without conversion
Pablo humano
No, because i receive the data in a char*, but when I try to save in a double, the program give me a syntax error, I need convert it con atoi() for save in the double, but the buffer receive the number with �OV and the conversion fail,
V01D
Pablo humano
And the problem is why i receive �OV with the long number like 3640214590 but with other like 576 i don't receive it
V01D
#inlcude <climits>
std::cout << INT_MAX << '\n';
V01D
/report english
Francesco
I am sorry, i make an error
Daniele
#inlcude <climits>
std::cout << INT_MAX << '\n';
I don't think this is going to fix his issue
Daniele
I mean yes the program doesn't crash anymore but I think there is the issue of why python gives back those strange numbers
Pablo humano
I don't think this is going to fix his issue
Okey sry, now i try to get the msg with a string, and i show the error, the previous time I try to (char* )str but i have to do this casting (void *)
V01D
I mean yes the program doesn't crash anymore but I think there is the issue of why python gives back those strange numbers
Bc the file size is that large I assume
Daniele
Bc the file size is that large I assume
well I didn't understand his previous program so I'm not going to say much lol

You should pass const char* when using char* in general

Use & benefit of struct keyword ?
Pablo humano
Filesize seems bigger than what integers can hold
yes, but i didn't use an integer, I used a double. I think the problem was in the char
Daniele
yes, but i didn't use an integer, I used a double. I think the problem was in the char
a double is a double precision floating point number

not a 64 bit intger

you either need a long int, or a long long int
Ruslan
hello
Daniele
or he can use an int64_t defined in stdint.h
Pablo humano
you either need a long int, or a long long int
okey, i go to change the double for a long long int thank you very much
