Thank You ❤️

Forgot to delete it.
And he was using printf in C++ code idk why.
Even in C, please, do not use the formatting functions, they are deadly trash. Those functions are the rusted barb wire that you keep in the back of you cramped garage in case it gets useful

Stuff like setprecision modifies global state of the output stream?

They just work and are simple to use, why not?

Because they tend to lead to enormous and easy to exploit security weaknesses

And add ; after clrscr

I think you have to write std:: before cout
The fact he didn't get what he's writing is another problem

isn't it part of iostream
I don't think so I work on Dev C++ and it's not compiling I add std:: before (cout, cin, endl) or add "using namespace std;" above main function

I'm new in programming section. That's why it's difficult for me.

You just need to study a lot. Nothing else

The first lesson you should take is don't ever use Turbo C++

Can you suggest good software for me!
Francisco
Depends on what operating system you're using
Francisco
Microsoft Visual Studio is the best. There's others like CodeBlocks, VSCode, CLion...

Use Dev C++ or Code::Blocks
Why would you use those things only suitable for freshman lab works?
Vitaliy ◀️TriΔng3l▶️
(not even for them actually)

There's Visual Studio 2019, with an easy to use debugger, with Concurrency Visualizer, with source control integration

I'm not using any Idea, I'm using make files on Linux OS but Dev C++ was my best IDEA when I was fresh
Francisco
I lasted with Dev C++ like 3 months. Then I moved to Linux and since then I use Atom + gcc/clang

iostream.h is not standard C++
void main is not standard C++
conio.h is just a piece of shit

Cout and Cin are not defined in your program

#include<iostream>
int main() {
int first = 0, second = 0;
std::cin >> first >> second;
std::cout << first + second;
}
Francisco
#include<iostream>
int main() {
int first = 0, second = 0;
std::cin >> first >> second;
std::cout << first + second;
}
I really want something to explicitly tell the compiler that a variable is uninitialized
Anonymous
Francisco
int a = void;
Francisco
Something like that
Anonymous
And why do you need that?
Francisco
That's another option
Francisco
Doing that, you explixitly tell the compiler that the variable is uninitialized on purpose
Anonymous
I think that variables must be initialized always

Yes, I understand
Why do you need uninitialized variable?
Francisco
I think that variables must be initialized always
I agree, but sometimes doesn't make any sense to initialize it, like reading from cin
Francisco
Why would you initialize a variable to a value you know is garbage? Just let the compiler know it is initialized so it can give better warnings
