Do you not know?

Why does if (a,b,...) exist in c++? It seems so useless

Its evaluates both expressions, but only uses the result of the last.

I thought you guys knew c++

Yes shelly

But why does that exist?

So whats the problem?

It seems so useless

Is their any applications with that?

My bad

Not many. It's only used when the first expression has a side effect

I read doesn't here

Ok so like when the first expression mighr change the one to the right

Makes sense

It can also be used in other stuff, like for loops. for(int i = 0, int j = 0; .... ; ++i, —j) ...;

There this operator is maybe more useful

True

I have to implement this program

I have already created an exchange function for the second carrier now I have a problem with the association

void randomArray(int v[],int DIM){ for(int i=0;i<DIM;i++){ v[i]=i; } cout<<endl<<"V PRE-SHUFFLE"<<endl; for(int i=0;i<DIM;i++){ cout<<"-"<<v[i]; } for (int i=DIM-1;i>0;i--) { //SHUFFLE FISHER-YATES int j = rand()%(i); swapInt(&v[i], &v[j]); } cout<<endl<<"V SHUFFLE"<<endl; for(int i=0;i<DIM;i++){ cout<<"-"<<v[i]; } }

int vrand[DIM/4]; randomArray(vrand,16); for(int i=0;i<DIM/4;i++){ int num=v1[i]; v1[i]=vrand[num]; }

Can you suggest some good articles, books or videos about optimization (cache-friendly, data-driven development)?

My array takes totally random values😂😂😂😂

Hello

Hello!

Guys how can I launch the command line "grep -oh "[a,e,i,o,u]" file.txt |wc -w" in C with the execlp()?

You can run that command with the system () function

I takes a string as a parameter which it executes it in the command line

And it return the status code of the command that was ran

I have a question about libcurl. The documentation is a bit confused about the parameters size_t size, size_t nitems of CURLOPT_READFUNCTION. Could you explain me what do they represent?

Oke, thankyou

Hi

I,m new in this group

Please anybody tells me about the basic of c language

I want to learn the c language

Thanks to

Thanks

Please allow me to chat

lol

Please allow me to chat

No

Please allow me to chat

Yes

sorry guys for the disturb ,

I must write a code for searching a value in the array

in this mode

In questo modo

And I think this code

wtf is going on with these weird algorithms on a paper

int searchIndex(int v[],int vrand[],int DIM){ for(int i=0;i<DIM;i++){ cout<<"-"<<v[i]; //print array v1 } cout<<endl<<endl; for(int i=0;i<16;i++){ cout<<"-"<<vrand[i]; //print array vrand } for(int i=0;i<DIM;i++){ for(int j=0;i<16;i++){ if(v[i]==vrand[j]){ return j; } } } return -1; }

wtf is going on with these weird algorithms on a paper

to understand the logic

I must write a code for searching a value in the array

Loop around and if

Why?

To find it

Compare each element in an array

I have a problem

the first element of the vrand vector is added to my first array

I have a problem

I'm sure you do

the first element of the vrand vector is added to my first array

The thing you're doing is easy and you're doing it right by making sure you're doing on paper first but a little logical thought on it and you'll get it right.

Does somone have some good website where i can find a good explanation of translation schemes in C(topic related to parsers and lexers)

is there a method that converts a string 1011010101 .. into the corresponding Ascii table value (such as "c")?

use strtol and then cast the into to a char

strtol and cast could work? edit:i think that if you asign strtol to a char you dont need to cast

yea

Define a class sports having sno,sname,fees required function and write a menu driven program to append records in a file and delte records of a give sno

please help me with this^

use strtol and then cast the into to a char

"011000110110000101110100" - this string is "cat", how to convert ?

"011000110110000101110100" - this string is "cat", how to convert ?

char *bindat = "011000110110000101110100"; char c = strtol(bindat, 0, 2); printf("%s = %c = %d = 0x%.2X\n", bindata, c, c, c);

this is easy

do it

you can do it

this is easy

any link for the solution?

no, just start writing it

that’s all

char *bindat = "011000110110000101110100"; char c = strtol(bindat, 0, 2); printf("%s = %c = %d = 0x%.2X\n", bindata, c, c, c);

Now I try

no, just start writing it

okay thank you

Hey guys, I plan on creating a C program which: listens at a port and is sent a request with a text field (obtained from a cookie) (HTTP request, i guess; i don't know a lot about networks) does some stuff with that text and if there is no text field, it must send a text to the sender which is their cookie data from the next time onward (HTTP, i think..) So i should learn working with sockets, right? or is there something else?

http & sockets

^

http & sockets

in that particular order?

I don’t think so

both
