Good job

Hello, I have solved this problem https://www.hackerrank.com/challenges/angry-professor/problem And this is my code- https://pastebin.pl/view/76cf499d Can anyone help me on what I'm doing wrong as only few test cases are passed. Thankyou.

so if x =0 an i =1, if you then set x= ++i x now =2 and i now = 2 if you set x = i++ x now =2 and i=1

My question is why ++var L-Value-Expression in C++ (in C both R value exp), there is no link between your answer and my question

But not free, and digital version is not available as far as I know.

The fist edition is in PDF format.

I wrote King an email asking if he will be updating his C programming book. He said he's retired. So I sent him this clip. https://www.youtube.com/watch?v=9YWoCPd5boE

The only software a C++ programmer needs is a compiler and an IDE

get it, tks

ostream& operator<<(ostream& out, Person& p) { out << "a:" << p.m_A << " b:" << p.m_B; cout<<p;

Guys how does it work

Person operator+(Person & p2) Person p3 = p2 + p1; //seems like : p2.operaor+(p1) This one is to understand

Confused 😕

This one is easy to understand

Guys how does it work

You override binary operator<< for left operand being ostream& and right being your class.

yes, now I'm learning override course

Bt, I can't get it how does cout<<p work,which the next one is easy to understand

You override binary operator<< for left operand being ostream& and right being your class.

Person p3 = p2 + p1 equal p2.operaor+(p1) What does the cout<<p equal ?

Person p3 = p2 + p1 equal p2.operaor+(p1) What does the cout<<p equal ?

operator<<(std::ostream&, Person&)

With std::cout being global ostream object

Bro it's hard

WAP in CPP to define a class which represents temperature in Celsius. Define another class which represents temperature in Fahrenheit. Define a common friend to see if two temperatures are same.

can anyone plz help me to understand friend function and make this program

can anyone plz help me to understand friend function and make this program

i dont know about this function and also doesnt have clear understanding about it

Please guys i am having a confusion i want to learn both c and c++ which one should i learn first. Note: I have search on google but still not satisfied.

If your end goal is C++, then learn C++

People say C or C++ without asking the important questions. Mainly: What do you want to do as a programmer, what do you want to build?

Are there external librarys for the topics you like, and what language are those? Meaning: Which programming language would you encounter the most?

There is an error

Yeah

You are saying c99, but using c89 on the cli

Cool

Lol, i tried

Hi guys ! I am new to C ++. To manage long options in C I use "getopt.h", and I would like to know what is its equivalence in C ++?

Manage long options?

https://www.boost.org/doc/libs/1_58_0/doc/html/program_options/tutorial.html for example

Manage long options?

yes, like : program --Sort array.txt

Oh like arguments passed to the command line

Why not use argc and argv for that

https://www.boost.org/doc/libs/1_58_0/doc/html/program_options/tutorial.html for example

Great! Thanks !

Why not use argc and argv for that

because there are libraries that make the task easier

Easier than just plain strcmp and boolean flags?)

I think yes ! to handle short and long options yourself requires more lines of code than if a library is used. don't you agree with that?

What's the code to add text effect in output of C++ program ?

It is platform-dependent

What OS are you on?

Did you try FASM forum? They have some OS construction experienced people there.

No, since FASM is a language. I will try, thanks

Is there any way to point 'H'?

char* c = "H" points to single char

it points on the beggining of the string buffer

char* c = "H" points to single char

it points to H\0, and you should add const.

eg. char* l = "lol" l[0] => l l[1] => o l[2] => l where char* l is only memory pointer, not actual value

it points to H\0, and you should add const.

does it add null terminator automatically?

yes

oh f

my bad then

Imagine having to insert a string termination char each time

It is nasm all over again
