My code is a question, I'm learning to program and using the codcad site, the question is in the image. When I send my code, it only has 60 points of 100. I would like to know what I am doing wrong.

Follow the image.

Edit: I tried to solve the question using only what I learned on the site, more advanced things still do not know very well, so I may have gone through a more complicated logic.

Input The input contains a single line, containing five Ni numbers (1≤   i ≤5), all with one decimal place, indicating the notes received by the   association in one of the requirements.

Output Your program should print a single line, containing a single   number with exactly one decimal place, the final grade of the school of   samba in the considered subject.

obs: I'm sorry for anything I've done wrong I'm new to the site and if I'm done wrong I'll accept suggestions and tips. obs2: I accept tips and suggestions as well for programming. Thank you for your attention.

Following is an implementation of the exercise:

#include <algorithm>  
#include <array>   
#include <iomanip>
#include <iostream>
#include <numeric>
#include <tuple>

int main()
{
    std::array<double, 5> notas;
    std::generate(notas.begin(), notas.end(), [] {
        double nota;
        std::cin >> nota;
        return nota;
    });

    decltype(notas)::iterator menor_nota, maior_nota;
    std::tie(menor_nota, maior_nota) = std::minmax_element(notas.begin(), notas.end());

    std::iter_swap(menor_nota, notas.end() - 2);
    std::iter_swap(maior_nota, notas.end() - 1);

    double soma_notas = std::accumulate(notas.begin(), notas.end() - 2, 0.0);

    std::cout << std::fixed << std::setprecision(1) << soma_notas;

    return 0;
}

Here I am using the C ++ Standard Library to do absolutely everything, but you can - and, from a learning point of view, you should - reimplement these algorithms manually using simple loops and logic.

Algorithm logic:

Read all the elements for a container ( array , vector , etc)

Find the highest and lowest marks

Remove (or in this case, move to the end of the container ) found elements

Add the remaining elements

Print the formatted result correctly
