Yes.
The program invoked default ctor in this line:
String sample;
So that means I allocated memory for char* string
Then in this line:
sample = String("Test");
I accessed to that memory and try initialize
sample = String("Test")
There you rewritten object that created by default constructor with object that created by second constructor
Daulet
Daulet
sample = String("Test")
There you rewritten object that created by default constructor with object that created by second constructor
First object had pointer to allocated memory. But then you have other object without allocated memory
Дон

Aaaah, you mean program in second line will create temporary class instance with immediately invoking ctor(const char*)?

Is it possible to avoid the potential memory leak?
char* string = (char*) malloc(100 * sizeof(char));
void foo1() {
string = nullptr;
}
void foo2() {
string = ... //I want use the past allocated memory block, is it possible?
}

It is possible if you write your own allocator instead of using malloc/new. But you shouldn't be doing it

Ok, I think in this situation I can just free memory and allocate it again.

Can anyone, please, give resources to learn assembler basics. I just want to know how my cpp program actually works via checking disassembly

There are tons of assembly tutorial on youtube, i learned assembly from kupala

You need to at least understand the architecture itself, there are arm, x86. But please don't do DOS assembly

Its two days that i am asking it

Google launched a new programming language called Carbon. It’s an experimental successor to C++
Here’s a code comparison between C++ and Carbon.
Dima
its a faulty language from its start just like any other which is trying to compete with c++

what about rust, i've heard people saying it's a safer language that does what c++ can do

It is safer language with changing the way you think of an object (narrowing and ...) So it's much harder to rewrite a code from C++ to Rust against rewriting a code from C to C++

Is it all the code? It's impossible to tell looking at only this.
Could be something like this, could be something else

I asks you about the disassembly part and you said you don't remember
Yes because i have decompiled it two days ago

My words is good luck for your reverse engineering journey
\Device\NUL
Yes, decompiler can make revese engineering easier but there are rare case where you can't use decompiler and most read assembly directly

I dont want to check every concept that ı learn if it is still being used or not

I expect from this code 40 30 20 but top is undeclared it says?
Дон
And correct if-loop in push function:
if (st->top == st->size - 1)
X
aaa yes or st.top?
X
because top is not declared lol in that function but ı need to use that from struct

I want to declare a variable in a class, assign it some starting value and change it further, but I want the variable to be the same for each instance
static int = ... something like this
How to do this?
Дон
Are you tried google it?
On the advice of this gentleman, I was able to find the answer to the question above, the question isn't actual :)
Дон
Yea but Didn't understand 😓
I would recommend finding a good book on C++ for beginners, there are consecutive topics. And there you will find the answer to your question.

Of course but it is easier than converting from C++ to Rust
