wow the GUI integration is nice

I have not used it. Just searched for it after your post. It was made available only in March of this year

If I set a breakpoint somewhere, so does the debugger do something like this. Executes the program till that breakpoint and waits at that breakpoint??

Yes. When a breakpoint is hit, it results in a special trap instruction and the OS on seeing that trap instruction gets the interrupt associated with it which would be that of the debugger. The debugger uses this interrupt handler to set the CPU in a special mode where it runs one instruction after the other (pipelining is diasbled) and following the istruction it traps into the debugger again. This is how the debugger takes control of your program's execution.

If I create a class and in the constructor I create a stack and dont give it any data then can I add to that stack later??

Explain the question more please

Can anyone help me to understand this line if a =0 b= ++a + ++a;

class Freqstack { public: Freqstack() { stack<int> s; unordered map<int, int> m; } void push(int val) ( s.push(val); m[val]++; } int pop() { } };

This wont even compile. You cant access s and m in push method. You should make them data members instead of local variables

Like write them outside the contrsuctor

Like: class Freqstack { private: stack<int> s; unordered map<int, int> m; public: Freqstack() = default //Rest of your class };

Like: class Freqstack { private: stack<int> s; unordered map<int, int> m; public: Freqstack() = default //Rest of your class };

void push(int val) { s.push(val); m[val]++; if(m[val]>max) { max=val; } }

Since there already a function push...but we are writing a new push function with same name..it's not working how to solve

Your push function is in class FreqStack. Put your full code in pastebin.com

I pasted there ..do I download it and send it to you

paste the link here

Your code is not even in a compilable state. But even otherwise, I dont see any reason why the compiler would complain of a clash. As long as your push and pop are in FreqStack class's namespace there should not be any issues.

I'm getting error: no matching member function to call to push

Look at LIne 22: stack int> temp; while(s.top()!=max) temp.push(s.pop()); What is temp? You cant ask for help here with silly coding issues. Try to understand your compiler's error messages

Temp is a stack that I created in pop function

Yes but you have written stack int> templ. It should be stack<int>

In the original code it's there

If you cant properly paste your code and expect us to help, then we cant be bothered either

This is the original code

Did you check the interface for pop on stack?

Yes this pop should return the most frequent element

When I asked if you checked the interface, I meant if you read the documentation for it? https://en.cppreference.com/w/cpp/container/stack/pop

@SilhouetteInDark I started debugging the code but when I step over and the debugging goes to input line, how to give input

It is not allowing to type anything

@SilhouetteInDark there's a exception thrown at line number 26, segmentation fault. can you explain why?

if debugger stops at some line lets say line no.a then does it mean the previous line thrown exception?? or does it mean line a thrown exception

How am I supposed to know what is line 26

sorry i thought the code i sent before had line numbers. my mistake. anyways see this https://pastebin.com/vLAMwnt7

In your Node class, you are not initializing the left and right pointers. So they will have invalid values.

thanks alot

It's like asking, Hey , I know how to use a chainsaw , how much income and how money can be earned.

Programming language c++ how much income and how much money can be earned

It’s just a C++ standard with new features

I don’t use C++ I’m not sure

I don’t think knowing a older standard limits you from doing something

Like what are the features?
