memset() works on raw memory, so you filled the bytes of 'a' with the value 50, which in turn makes every double value in a be 0x3232323232323232, which who knows what that is. If you want to fill 'a' with doubles having the value 50.0, you should use std::fill(). ...

How to Use memset() in Arduino In Arduino we used memset() to set data from n bytes of given value to destination with specified number of bytes. memset() copies or replaces given n value bytes to each of the first n characters in the destination block. To get more understanding about...
