When do you need to flush the stream ?

Mihail

When do you need to flush the stream ?

well when you want the characters that you "printed" to actually print

Mihail

but std::cout is line-buffered, so it does that with '\n'

I want know about c language. Full course

Learn c by writing something more closer to machine understanding like drivers, or some os kind of stuff

Else start with c++ which is superset

What is (- >) that means??

member operator. It has two operands. The left operand is a pointer, who points to a struct or class object. The right operand is the name of a member of that object. The result of the operator is the reference of the member of the object pointed by the pointer.

Liam

Are you sure? Do you have any reference to that?

Azrul

New =(data*) malloc(sizeof(data));

Azrul

New =(data*) malloc(sizeof(data));

What is this mean??

There is nothing like this in cpp. Either you should allocate memory using new operator or malloc Using new operator: <struct_type> data = new <struct_type>(); Using malloc : <struct_type> data = NULL; data = (data*) malloc(sizeof(data));

New =(data*) malloc(sizeof(data));

malloc sizeof(data) bytes of memory, and returns the pointer to the memory snippet, if success. Then, convert the type of the pointer from void* to`data*, and store it in `New.

Sure.

know anything about a recursive function?

Yah

Then i guess you just need to trace it step by step using a pencil and paper

In d second step x bcming negative then y answer is 7

S.

Like … fun(4, 5), x>1, fun(2, 7), x>1, fun(0, 9), now x is not >1, print y, the first output 9; look back to the upper level, in fun(2,7), now if block is finished, print y, the second output 7 …

Sir i want to run graphics program in codeblocks

Kaku

Then how can i do ?

No. x doesn’t become negative

Ha sry typo mistake second round x bcming 0 but answer is not matching

Hello :-) I'm looking for a nice solution for static vector of vectors added in constructor. constructor(int X) { STATIC_VECTOR[X].push_back(this); } but

Dotevo

vector < vector<Objs*> > STATIC_VECTOR;

Dotevo

vector containsts const elements. Should I change it into vector < vector <Obj*> * > ?

Francisco

vector containsts const elements. Should I change it into vector < vector <Obj*> * > ?

Every vector<Obj*> is const? Then it should be vector<const vector<Obj*>>

Dotevo

I do not want to make it const but vector contains only const values.

Dotevo

and i cannot call push_back() there

S.

You mean Objs* is const?

Dotevo

1. vector < vector<Objs*> > STATIC_VECTOR; 2. vector<Objs*> n = STATIC_VECTOR[i]; 3. n.push_back(this); NUmber 2 will not compile because there is a casting from const.

Dotevo

It is possible to avoid it with: 1. vector < vector<Objs*> *> STATIC_VECTOR; 2. vector<Objs*> *n = STATIC_VECTOR[i]; 3. n->push_back(this);

Dotevo

but maybe there is a nicer solution then use pointers.

Silvestr

sorry foe dumb question, but how delete shared pointer?

Silvestr

I mean I passed it to function and want clean it inside function

Ariana

shared pointer?

Silvestr

shared pointer?

Yeah, I have two threads that access to some resource(no data races), but problem is in next -> when one thread use resource I want delete this resource and in second thread just check if it is not a nullptr

S

student(int r):roll(r) {}

S

what does it mean?

Silvestr

What is best practice for doing such things?

Silvestr

student(int r):roll(r) {}

initializer list

Silvestr

you call costructor of roll object
