(ref) VS (out)

Question

i want to ask what the defferances between passing variables to functions by out word and ref word?
THANK YOU!

Answer 1

@ Ollie Q I do not agree with you, on the ref part.

by val : doesn’t change the value for the rest of the program
But the ref keyword is especially used for changing the value for the rest of the program.

Have a look at this example code.

out parameter can be uninitialized
ref must get initialized

Answer 3

Answer 4

Hi Star PRO X
the out keyword changes the value of the varible in the function and outputs the varible in the program.
the ref keyword acepts a varible into the function but doesn’t change the value for the rest of the program
i hope this helps

Answer 5

i see that out in your example that out and ref working same... they changed the value of given variable on calling that's all....
