were u having issues ?

[buoyant hornet]

Yeah, I was trying to solved this problem but when I submitted it, I got "Wrong Ans", I've try my code and I got the same output

Um, I was new to discord so I don't really understand the features. Can you see my question photos?

[haughty shuttle]

what is fixed?

why are you setprecision(i) you need to help us so that we can help lol

[buoyant hornet]

Isn't it is used for setprecision?

[wintry aspen]

that its correct setprecision(1) will set precision to 1 decimal

[buoyant hornet]

Sorry, setprecision (1) so I can keep 1 number behind comma, because the average that we want to compare are 4.5. If I try to find average without setprecision (1), if I got like 4.6 it will turn to 4 and made the average was less than 4.5 when it was supposed to be greater than 4.5

[buoyant hornet]

Sorry for my bad English too..

[wintry aspen]

#include <bits/stdc++.h>
#include <iomanip>
#include <iostream>
#include <string>

using namespace std;
int main() {
  int n =0;
  float result =0, mark =0, sum =0;

  cin >> n;
  for (int i = 0; i < n; i++) {
    cin >> mark;
    sum += mark;
  }
  result = sum / n;

  cout << fixed << setprecision(1);

//fix the if's
  if (result == 3) {
    cout << "None" << endl;
  }
  else if (result == 5 ) {
    cout << "Named" << endl;
  } else if (result >= 4.5 ) {
    cout << "High" << endl;
  } else if (result > 3 ) {
    cout << "Common" << endl;
  }

  return 0;
}```

[buoyant hornet]

I still got wrong ans with this code

[wintry aspen]

see comment ``fix the if's`

[buoyant hornet]

Do you mean I should changed the if?

also a small note I reccomend against using #include <bits/stdc++.h>

it's non standard and should honestly never be used

[haughty shuttle]

^ x2

and using namespace std

[haughty shuttle]

see i was confused because of random fixed which comes from std::fixed)

[buoyant hornet]

Ok! Thanks for telling me

[buoyant hornet]

Okay, thanks

[earnest pier]

In general don't use non-standard headers unless they're from an external library that's known and maintained
any file that ends in a .h is not part of std c++ libs

(Except those internal includes but no one uses them, they're only used by stdlib)

[earnest pier]

using namespace std is probably fine in this scale
but afaik doing that include loads the entire stdlib into the compiler

Not that I'd ever do it but yk

[haughty shuttle]

yep

Name collisions

[earnest pier]

And before anyone points out that C headers are a part of stdlib
while you're right
even the compiler tells you to use the C++ variant instead

cmath instead of math.h for example

@buoyant hornet Has your question been resolved? If so, run !solved :)
