Answer 1

im not even good at c++ but this was easy,youre using cout without declaring its namespace,duh!
you either use std::cout or declare
using namespace std

Answer 2

What are you talking about? I legitimately can't figure out what's missing from the code. I just started learning C++ around 2 weeks ago.

Answer 3

Thank you, @Brains!

See, Akib Reza, that wasn't so hard

Answer 4

@Brains why does it output 2324 instead of 2325? Isn't the code increasing each of the inputs by 1?

Answer 5

Not work like you think... Your static variable i "remember" last value setted (thanks to static modifier) but it reset for different template types because is like you defined 2 func functions (one for int type and on for double type) but this is maded by compiler and hided to programmer

Answer 6

Well namespace std was in there but I didn’t have the std::cout; in there
