why this input failing?

Subhajit

images not allowed here?

Dima

no, read the rules

Subhajit

no, read the rules

Ok

klimi

why this input failing?

it works without problem

Subhajit

In hackerrank it works with custom input but by submitting it shows wrong answer

Subhajit

Pic not allowed so i can't show

klimi

Pic not allowed so i can't show

there wouldn't be more information either way, try reading the hackerrank the exercise one more time if you haven't overlooked something

Subhajit

There are 4 test cases

Subhajit

I put all the value one by one in custom input. It worked

Subhajit

But when i submit it shows wrong answer

Dima

Wtf why warn limit is 3

klimi

Wtf why warn limit is 3

cuz this is not offtopic

Subhajit

Warn for asking for help ?

klimi

Warn for asking for help ?

No, for ignoring rules and crossposting everywhere (offtopic is not meant for asking C/C++ questions)

Anurag

But when i submit it shows wrong answer

Sure about the display formatting?

Subhajit

Sure about the display formatting?

It's not printing all the decimal values

Subhajit

One of member said to use setprecision

Anurag

In hackerrank it works with custom input but by submitting it shows wrong answer

Replace long with long long...see if that works.

Subhajit

Long was right It's about the last floating values

Harsh

Hi

Anurag

Does that problem specify the number of digits after decimal?

Subhajit

Does that problem specify the number of digits after decimal?

Yes

Subhajit

Getting error that setprecision is not declared in this scope

Anurag

import <iomanip> use cout << setprecision(number of significant digits asked) << d << endl;

Anurag

import <iomanip> use cout << setprecision(number of significant digits asked) << d << endl;

Subhajit

@subhajitlucky

I copied his code it worked

Subhajit

But i typed exact same code

Subhajit

It didn't work

Anurag

Must have made a mistake...check

Subhajit

I have taken ss it's exact same

how to read C++ template error?

Pavel

how to read C++ template error?

I usually search where the error starts mentioning the line where the template code was called from, and start reading from that line (I think it's usually up from that line)

Hello, c++ coders. I am beginner in clear c++, recently i wrote only on Unreal Engine's C++ framework and a little on standart c++ library. I have a question. Is visual studio code good code redactor for c++? Is it friendly with CMake, and other C++ tools?

Hi guys, can you help my please with a probleme?Create the Integer class. Numbers must be in the range -128 to 128 . In case of exiting the tuning fork, display the error message. Overload the ++ operator as a member function and -- as a friend function. Overload the operator + as a member function and - as a friend function. To overload as member functions the operators and >> (adding and subtracting from the integer a given number of units) C++

I dont know how do it

I dont know how do it

Where are you stuck? What have you tried?

Gheorghe

#include <iostream> #include<cstdlib> #include <time.h> #include <math.h> using namespace std; class Intreg { int x; public: Intreg (int xx;) { x=xx if (xx>-128 && xx<128 ) return true; return cout<<"Eroare"<<endl; } void Afisare() {cout<<xx<<endl;} Intreg operator++(Intreg xx) {Intreg s; s.x=xx.x+1; return s;}

#include <iostream> #include<cstdlib> #include <time.h> #include <math.h> using namespace std; class Intreg { int x; public: Intreg (int xx;) { x=xx if (xx>-128 && xx<128 ) return true; return cout<<"Eroare"<<endl; } void Afisare() {cout<<xx<<endl;} Intreg operator++(Intreg xx) {Intreg s; s.x=xx.x+1; return s;}

you return true from constructor?

I think the program I wrote is wrong
