C Default Template Paramter

Instead, c++ forces that default template arguments are only allowed on a class template. Whenever you have a function that should support a braced initializer by defaulting the template parameter to some type, use a default template argument. Using the other parameters of the template (here the default parameter uses map). Assume i have a template (called exampletemplate) that takes two arguments: The catch is that c++ does not consider default parameters when performing template deduction. For class templates, this behaves mostly just like default function arguments: Template t sum(t a, t b, t c=????) return a + b + c;
