Answer 1

Either use designated initialiser for the integer fields( like you did for double ones ) of union or put an extra brace to initialise the union field of the struct to initialise the union.

Answer 2

Thank u.
But why i should put braces ?

Answer 3

Ahmed Mahmoud because second member of the struct is an union and that is how you initialise an union.

Cpp reference says " When initializing an object of struct or union type, the initializer must be a non-empty, brace-enclosed, comma-separated list of initializers for the members "

See this for more info about initialising structs and unions 👇
