Logic is simple, try yourself if you find any difficulty then ask

How can i access a class instance in a function
redfox
Let's say that i have made a class instance in the int main and i wast to be able to access the same instance in a function
redfox
How can i do it
Marcio
The function must be a friend function of the class.
Read about.

Along with description what you expect to see and what in reality you see, and probably add your code too

class Point {
public:
double x, y;
};
class Vector {
public:
Point start, end;
};
int main() {
Vector vec1;// define vec1 of Vector class
vec1.start.x = 3.0;
vec1.start.y = 4.0;
vec1.end.x = 5.0;
vec1.end.y = 6.0;
}
redfox
this is the code i want to write
klimi
redfox
but i want the
vec1.start.x = 3.0;
vec1.start.y = 4.0;
vec1.end.x = 5.0;
vec1.end.y = 6.0;
part to be defined in a function

Check your braces… the printf seems to be “flying”…

a[i] is a array with integers contains even and odd numbers, i am trying to delete even number from that array
klimi
a is a pointer
Anonymous
Actually i am in learning stage, i am not a pro
klimi
And you with & you are taking the address of a pointer of int
klimi
Actually i am in learning stage, i am not a pro
Have I said such somewhere? Or what is this comment purpose?

class Point {

vec1.start.y = 4.0;
vec1.end.x = 5.0;
vec1.end.y = 6.0;
}
I don't see a problem with this, are you getting any errors?

There is no problem

redfox
Oh okay :D
There is a problem but not that type of problem
I just want to make the value assignment in another function then main
klimi
Can you help me with that program? I am not getting output
Well I am trying to help but you seem to be ignoring my comment
klimi

You can do that, all attributes are public
redfox
How tho
klimi
I didn't get this
You need to provide an address where to store the int, but you are not doing that

What different is between printf("___");
and cout<<"____";

Because in school we learn with printf... but when i search tutorials i find with cout...

printf("___") it's from C
std::cout « "___" it's from C++
That's the difference

Anyone can suggest a good book about architecture and design for software ? Something to read and improve for work ...

This is a vast field and there is no one book that does it all. There are different books for service oriented architecture, microservices design, cloud architecting, risk aware architecting and so on. And now the line between development/testing and devops has blurred so much that developers are required to be atleast familiar with Devops tools. More so for architects where they should know CI/CD, Ansible, Puppet or Chef like the back of their hands. Even if it is just pure software design that you are interested in, the landscape is changing. People are moving away from Object Oriented Analysis and Design which was the best thing in software world over the last decade. This is primarily because objects encapsulate mutable state and also share state both of which lead to data races in mukticore programming and hence OOAD is not conducive for concurrent programming. Locks don't help either because they are not composable. So functional programming is back in fashion now and there are so many books on this topic. So look at what you want to learn first

Sorry I cudnt resist my self from sharing my experience of taking interviews of about 20 guys..10+ years exp guys!Out of 20 candidates 19 just explained me OOP as 3 pillars ..Real word realisation etc n blah blah..! One guy was close to explain that ...! What is up to the people?Wrong books wrong notes ?This is 16k+ group how many of you know OOP in real ?N how many of u ever read a good book or tutorial!N how many of u know uncle Bob😂
Shourya
Read my post above yours
What a timing ! I too switched to functional paradigm..But still in interviews people ask OOP and me too...And job major openings are for OOP..And specially for fresher OOP is required...But looking at their answers ..Uncle Bob will be angry😂

You can use sdl2 with your C++ program. Just don't forget to include SDL2 headers.
