you and your C# style, shush

Dima
no
jaebie
I thought you asked me what I already know, sorry my bad
jaebie
what I don't know is how to calculate distance between two points
jaebie
btw, thank for the effort Dima and Klimi
jaebie
thanks*
Aquatica
what I don't know is how to calculate distance between two points
sqrt((x2 - x1)^2 + (y2 - y1)^2)
Aquatica
what if one wanted to get distance between to geo points
Uh, I guess like 3D points? You just add a z parameter to the formula
Dima
no
Aquatica
Idk I’ve never done this
Dima
longitude and latitude
Aquatica
I searched for it on stackoverflow though, it’s pretty easy

Either you print the sum in void function or make the function return an int i.e. sum

i have a question
Carlo
i have a function that returns a float
Carlo
is it possible to do
Carlo
char output[]=function();
Carlo
and i can't return anything from that function
Carlo
i can't use printf to format the output
Carlo
i need a string that contains dht2.readTemperature()
Dumb
readTemperature gives a float or a char array?
Dumb
an ez way could be casting the float to int and then change it in a string
or just some weird stuff with printf that I don t remember as well
Carlo

how do i redirect the output of the function to a variable?
Carlo
Dumb
how do i redirect the output of the function to a variable?
a function gives a value in output
could you save it in a var too and then operating on it?
Dumb
ah so it's a procedure
i thought it was a function
Dumb
if it's void you could use referencing parameters to change one or more value/vars
Carlo
readTemperature returns a float value,but i don't know how to store that value
Dumb
if it returns a value you could save it as below f.e.:
float temp = dht2.readTemperature()
//do some stuff on temp//
Carlo
thanks
Carlo
i don't know why but when i tried it didn't work
Dumb
maybe misspelling or a bad format
it happens

I need to swap the two numbers in different variables
short ans: use std::swap
long ans: change function signature to void Two_num(int &j, int &b);

Pass the pointer instead of passing the values directly

You should change the name "switch"

Does anyone know of a c++ book for beginners?

I see, that's probably why its not working

do you get verbose compilation error messages in your IDE?
