Template Arguments
In this lesson, we'll learn about template arguments.
We'll cover the following
Template Arguments
Template arguments can, in general, automatically be deduced for function templates. The compiler deduces the template arguments for the function arguments. 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
orvolatile
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
- Reference or pointer
- Universal reference(
&&
) - Value (copy)
