Template Arguments

Template Arguments #

In general, template arguments can be automatically deduced for function templates. From the user’s perspective, function templates feel like functions.

Conversion:

• The compiler uses simple conversions for deducing the template arguments from the function arguments.
• The compiler removes const or volatile from the function arguments and converts C-arrays and functions to pointers.

Template argument deduction for function templates:

template <typename T>
void func(ParamType param);

Two datatypes were deduced:

• T
• ParamType

ParamType can be a

• Reference or pointer
• Universal reference(&&)
• Value (copy)
