I have to preparation from zero level

So what should I do?

usually you don't link header files, you link libraries. It's hard to tell without seeing the whole project,

Can anyone let me know how can i improve my coding Skills?

like in this: int count = snprintf(strbuffer, sizeof strbuffer, "%d", x);

my brain was just defaulting to side-effects=bad

nah, I got what you meant. My side-effects=bad thing comes a book on LISP that I read. Thanks again!

İ am totally confused, i don't want to spend time to learn outdated c commands or functions so want to start from c++ book but as i see from pdf, it quickly pass the introduction part then cont with classes etc

Hi guys can someone help me with this exercise in C++. 14-Make a program that reads a 10-position vector and checks if there are equal values and write them on the screen.

So im figured out i need to redefine arrays at the end of that func But i dont know how Can somebody help me?

It helps

Practice questions from Hackerrank etc.

HELLO EVERYONE. Does anyone among us know how to use QT?? Is the usage language c++ or is there a special QT language??

The language is still C++ and all general C++ rules apply. Qt gives much more library functions and data containers than STL does. But it has different ideology, and sometimes you will be forced to use Qt stuff instead of STL just not to convert things back and forth. Also some of the libraries (and versions?) have different licensing (if you want to do something commercial, better to research this in advance).

You can imagine Qt as a language that compiles to C++

So what happens when we use swap? Could anyone help?

Here's the result: &svec1 = 0x7ffee30718b0 &svec2 = 0x7ffee3071898 &svec1 = 0x7ffee30718b0 &svec2 = 0x7ffee3071898

But why do both of their address remain unchanged after swapping the pointers?

Why should they change? You get addresses of memory on stack basically. Swap swaps the contents of the vector objects (pointers to dynamically allocated array, sizes)

Swap swaps the pointers but not the addresses of vector objects, is it what you mean?

Hey members who has c programming software

One more question, please. Whose address is &svec1?

I'm not sure if it's specified. As I see, vector has standard layout (at least in the implementation that I have) then it should be an address of the first member of the vector object. Imagine it can be something like this template<typename T> class vector { size_t size; size_t capacity; T* data; ... }; So in this case, if you do vector<int> a; then &a and &a.size will point to the same location. But if the data pointer is first, then the address of the object is the same with address of the data pointer variable (not the address that it points to). But that works only because vector has standard layout, if it didn't have (e.g. had a virtual function or destructor), then you couldn't guarantee even this.

Write a program that receives from the user a real number x and an integer n. Use loop to calculate x. The program for 0 <n must also work correctly.

Hello. how can remove escape characters from a string that i acquired from a serial port.

Hi, I feel confused..... I have this: typedef void *MdApi; // and then: void RegisterMdSpi(MdApi pMdApi); // is this the same?: void RegisterMdSpi(void* pMdApi); // what if: void RegisterMdSpi(MdApi* pMdApi);

How to add vector<int> vals; with some a positive and some a negative values?

<quote> typedef void *MdApi; // and then: void RegisterMdSpi(MdApi pMdApi); // is this the same?: void RegisterMdSpi(void* pMdApi); </quote> These two are the same. <quote> // what if: void RegisterMdSpi(MdApi* pMdApi); </quote> This is different. Here the parameter is void** and not void*.
