If the first part is true, short-circuit and return true, if not, check the second part…
Ludovic 'Archivist'
Or this->x < a.x || this->y < a.y || this->z < a.z?
Oh I pointed out even this one has the bug, which is why I posted another one
Ludovic 'Archivist'
Rather, I would have that be
bool operator <(const MyVector &a) const {
if(this->x < a.x) return true;
else if(this->x == a.x)
{
if(this->y< a.y) return true;
else if(this->y == a.y)
{
if(this->z < a.z) return true;
}
}
return false;
}
This one is the correct implementation

Hello everyone!Help, urgently need!
Given a real matrix of size m x n. Determine the number b1,..., bm, equal respectively to the differences of the largest and smallest values of the elements of the rows.
Please tell me how to write the condition itself here.

Hello everyone i would like to get your advice on a project i'm working on it now

I have a main program call coreprog and a second one called receiver
Anonymous
What is the best practice should i integrate receiver.h into coreprog and then execute fork and run the function of the reciver or should i use execl to execute my receiver thanks in advance of your answers

Thx

Which has a for ever loop

It is like a daemon

This doesn't matter
In that cas i have to integrate my header file into coreprog to instanciate the thread
Anonymous
And after the xompilation i will have one executable instade of two

It seems good idea better then fork and exec

This is normal, you can't study c++ in a month

Don't use online courses, they all suck. Read books, listen to lectures at your university.

Another good resource is official c++ FAQ site , you'll find it.
Another one is core guidelines by Satter & Stroustrup

question: fopen with w option rewrite the file or append data to it?
Al
@unterumarmung thanks
Al
what do i need to use if i want to append?
Ilya
question: fopen with w option rewrite the file or append data to it?
It is not mutually exclusive.
append is (Re)write at the end of the file.
w means simply "for writing"

what do i need to use if i want to append?

Learn to use the docs

No problem, coz C++ is making 2 sub-objects for you and u can call the one what u need.

If you want to work in C++ without reading, you are gonna need a parrot that can read

The use of inheritance where composition was the correct answer

Meaning
97% of programming courses and documentations for common libraries and patterns are only available as text, better get the hang of reading than wasting hours searching video tutorials

People who is CS students:
Do you have among your programming tasks any tasks related to matrix algebra, like matrix multiplication, or other operations?
Please state your country.
This question is for investigation on how to teach C/C++.

Brazil. Yes. We have analytic geometry and linear algebra.
But it is only prerequisite of studies on Graphic design

Do you have assignments to code operations with matrixes in your programming classes?
C.
Do you have assignments to code operations with matrixes in your programming classes?
In some courses, yes.
C.
But as for basic programming, no we dont have it, although matrix operations and things like Bhaskara formula are good for learning how to program, pseudocode and so

Im trying to sort the pairs in the set in descending order of second value
Javi
And what is the problem?
Chiranjeevi
The order which i get is not as expected
Javi
You are printing the map, not the set
Anonymous
Can some one explain me what is going wrong in this code https://pastebin.com/r8M3FV40
Because you output the map, not the set

Ok, sorry about that
