hello

I'm using google benchmark

some one know the definition of output?

Run on (8 X 2794 MHz CPU s) CPU Caches: L1 Data 32K (x4) L1 Instruction 32K (x4) L2 Unified 262K (x4) L3 Unified 6291K (x1) -------------------------------------------------------------------------- Benchmark Time CPU Iterations -------------------------------------------------------------------------- sort/128 4448 ns 5298 ns 144516

time & CPU ?

what are?

I have not problem with the rest

Just now I learning c programming...

What kinds of practice take me to the next level?

I am Mechanical student..not that much knowledge about programming...but I eager to learn it...

This might be helpful : https://dev.to/visheshpatel/how-c-program-converts-into-assembly-3m2f

I know the concept of memory

But I can't understand the function and variable

I am Mechanical student..not that much knowledge about programming...but I eager to learn it...

It doesn't even matter as long as you are interested

What kinds of practice take me to the next level?

Programming... Practice... If you are not CS student, learn basics of Computer Architecture and Operating Systems.

Can u plz help share me some notes about basic programming?

Mm ok bro...

Can u plz help share me some notes about basic programming?

it's not for chats, you must read books for this.

Well you can try reading SICP or S.Prata "C Premier"

That's y I asking in personal...sorry..

Hey

No, this is c/c++ group, no python here

By the way thanks for the advice. I'm beginner in cpp. I want to learn more core about cpp.

Just that your first word was related to python ¯\_ (ツ) _/¯

Seriously!?

Seriously!?

Yes!!!!

Yes!!!!

I don't even know python. Only i know oop pop basics. That's all.

And you said hy

🙄🙄🙄

Yeah, I underestimated decltype

Can you help me with how to do this with a comparator function?

Can anybody tell me how can I check whether all the characters in string contains 0,1,2,3,4,5,6,7,8,9 or not?.... Is there any good approach to solve this kind of question?

Using STL

Use array as index...

does someone know bubble .is here

Like create arr[10]

Use array as index...

Array as index??

Array as index??

U have to all the number 0-9?? Or just check only contain numbers??

Using STL

You can use find_first_of with "0123456789" and check that result is not std::string::npos http://www.cplusplus.com/reference/string/string/find_first_of/

Ah, wait

std::string::find_first_not_of in this case

You can use find_first_of with "0123456789" and check that result is not std::string::npos http://www.cplusplus.com/reference/string/string/find_first_of/

I will try this👍👍

You should practice on Hackerank website... It is good platform for beginners.

Is there other alternative

Is there other alternative

If you totally new then you should first practice very easy questions to become familiar with Syntax. Once you done with Syntax try different types of questions.

Is there other alternative

GeeksforGeeks, Hackerearth One more thing make sure you practice at least 3-4 programs a day, and also try different types of question.

when you make a pointer , you are creating a variable that points to the memory address of another variable right ? the pointer itself lives in the stack ?

Yes, the pointer itself lives in a stack

A pointer points to some memory It's not a "variable"

It's just stores some number that represents an address in RAM

It's just stores some number that represents an address in RAM

what if it points to a function that allocates memory on the heap

what if it points to a function that allocates memory on the heap

Pointer to function is a different story

node* create(char *question) { node *n = malloc(sizeof(node)); n->question = strdup(question); n->no = NULL; n->yes = NULL; return n; }

typedef struct node { char *question; struct node *no; struct node *yes; } node;

What's the question?

node* create(char *question) { node *n = malloc(sizeof(node)); n->question = strdup(question); n->no = NULL; n->yes = NULL; return n; }

It doesn't point to any function strdup just returns a pointer to some memory in the heap

What's the question?

just trying to understand pointers better and why my text book uses it in certain cases , for example you see above there is a node structure with two recursive members , the create function is also a pointer, and is used to create new structures

why is this function a pointer ?

why is this function a pointer ?

It returns one The function is not a pointer

It returns one The function is not a pointer

so if i declared it as node create() instead of node *create() would it operate the same way?

Ehm, no

Do stdlib.h/stdio.h do some kind of initialization of IO? I need to get rid of these includes and define all functions/structs manually, but fseek() crashes once I remove the includes.

stdio.h i think is required for input/output

well you need them if you don't want "undefined function" warnings

and once I remove them, it crashes right away
