In order to instantiate a function template, every template argument must be known, but not every template argument has to be specified. When possible, the compiler will deduce the missing template arguments from the function arguments. This occurs when a function call is attempted and when an ...

In the previous lesson (11.6 -- Function templates), we introduced function templates, and converted a normal max() function into a max<T> function template:template <typename T> T max(T x, T y) { return (x < y) ? y : x; } Copy...

functionName<dataType>(parameter1, parameter2,...); For example, let us consider a template that adds two numbers: template <typename T> T add(T num1, T num2) { return (num1 + num2); } We can then call it in the main() function to add int and double numbers. int main() ...
