Can you delete keys from a map in Golang using a variable that contains the name of the key instead of the key in quotations?
Solution 1:
You named your function delete, so inside it you shadow the builtin delete() function, and using it will refer to your delete() function. Rename it.
Also note that to achieve what you want, you don't need a loop, just use delete(map1, key2):
func remove() {
fmt.Println("Enter key to be deleted: ")
var key2 string
fmt.Scanln(&key2)
fmt.Println(map1)
delete(map1, key2)
fmt.Println(map1)
}
