What did I do wrong?
Clicking format tells you the answer in a better understandable way than run does:
prog.go:12:1: expected ‘}’, found ‘func’
This is because go now tries to use func as a field name in the struct, but thats not allowed as func is a reserved keyword.
Just close the struct definition properly, and your program will compile and run.
you forget to close struct body with ‘}’ . after i add this every thing work 
Thanks to both of you. That worked
