Answer 4

Hi Manav Roy,
Sorry but it seems your example doesn't work as I tested it.

`auto` type specifier doesn't help for this case. A variable with `auto` type specifier needs an initializer for its value, which is used by the compiler ti deduce a type considered proper for the data.

Answer 5

In python there is no such requirement as there is automatic data type assignment when a variable is Initialized. For languages such as C++ there is "auto" keyword for automatic data type assigning.

Answer 6

c++

Answer 7

Jojo Emeka an option is to find the int of the input and find out if there is more to the original input minus the int. If so it's a double.
