Because 64 is not output, is input.

setprecision() is supposed to display as many decimal places as we need, right? for some reason my code isn't working .-.
Sai Meghana
int a;
long b;
char c;
float d;
double e;
cin>>a>>b>>c>>d>>e;
cout<<a<<endl<<b<<endl<<c<<endl<<setprecision(3)<<d<<endl<<setprecision(9)<<e;

guys will you tell me please where i was wrong
Sai Meghana
the question requires 9 decimal places strictly

I think you need to print each one in different lines
Anonymous
atleast that set precision output line

i think there should be an error on setprecision
jack
its not declared in the scope
jack
but still it's giving output

i tried this too
printf("%.3f\n",&d);
printf("%.9lf\n",&e);

load integer values from both ends. I mean, split the string by = and then +. You'll get both integer values of left hand side and right hand side
I_Interface
i tried this too
printf("%.3f\n",&d);
printf("%.9lf\n",&e);
if u write on C++ - use only C++
Anonymous
then add the left hand side values and right hand side values

substract and then

divide by 2

if u write on C++ - use only C++
but wont it work with <cstdio> and <iostream> both included?
Rushi
Thanks I got it....

Hello, I have a class method GetData() in a defined class
Is there a way I could replace the instance pointer to that method with another one ?
Nomid Íkorni-Sciurus
for example, something like
MyObject->GetData = myPointerToFunction
Roxifλsz 🇱🇹
for example, something like
MyObject->GetData = myPointerToFunction
Why not just make GetData into a function pointer?
