Dạ Cảm ơn nhiều ạ.

Câu 31: 

#include <bits/stdc++.h>

using namespace std;

long long n,i,x,dem;

int main()

{

cin>>n;

dem=0;

for (i=1; i<=n; i++)

{

cin>>x;

if (30%x==0) dem++;

}

cout<<dem;

return 0;

}

program Tin_hoc;

uses crt;

var n,i,max:integer;

     a:array[1..100000] of integer;

begin

clrscr;

write('Nhap n: ');readln(n);

writeln('Nhap ',n,' phan tu cua day:');

for i:= 1 to n do readln(a[i]);

max:=a[1];

for i:= 1 to n do if a[i] > max then max:=a[i];

writeln('Gia tri lon nhat cua day A la: ',max);

readln;

end.

Khó hiểu wá bạng oi 😔

#include <bits/stdc++.h>

if (x==50) dem++;

}

cout<<dem;

return 0;

}

Chọn C

#include <bits/stdc++.h>

using namespace std;

long long a[100],i,n;

int main()

{

cin>>n;

for (i=1; i<=n; i++)

cin>>a[i];

for (i=1; i<=n; i++)

if (a[i]>=0) cout<<a[i]<<" ";

cout<<endl;

for (i=1; i<=n; i++)

if (a[i]<0) cout<<a[i]<<" ";

return 0;

}
