It work in dev c++:

#include <iostream>
using namespace std;
int main(){
    int a;
   cin>>a;
    int b[a];
    int tmp;
    int q=0;
    for(int i=0; i<a; i++){
            cin>>b[i];
            }
            for(int i = 0; i < a - 1; ++i) // i - íîìåð ïðîõîäà
    {
        for(int j = 0; j < a - 1; ++j) // âíóòðåííèé öèêë ïðîõîäà
        {
            if (b[j + 1] < b[j])
            {
                tmp = b[j + 1];
                b[j + 1] = b[j];
                b[j] = tmp;
            }
        }
    }
    if (a%2==0){

           for (int z=0; z<(a/2)+1;z++){
               if(b[z]%2==0)
                       q+=(b[z]/2)+1;
               else
               q+=(b[z]+1)/2;

               }
             }
             else {
                  int r=(a+1)/2;
                 for (int z=0; z<r;z++){
               if(b[z]%2==0)

               else

                  }
}


    cout<<q;
