cpp: In function 'void test(A<T>&)': template_test.cpp:11:10: error: expected primary-expression before 'int' a.hello<int>(); ^ template_test.cpp:11:10: error: expected ';' before 'int' 解决这个问题的办法很简单修改A::hello
functionName<dataType>(parameter1, parameter2,...); For example, let us consider a template that adds two numbers: template<typenameT>Tadd(T num1, T num2){return(num1 + num2); } We can then call it in themain()function to addintanddoublenumbers. ...

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 ...

Now we can create the main() function to wrap all of our code together: #ifndef __MAIN_CPP #define __MAIN_CPP #include "black_scholes.h" #include "newton_raphson.h" #include <iostream> int main(int argc, char **argv) { // First we create the parameter list double S = 100.0;...
C++ STL | array::get function template: Here, we are going to learn about the get function template of Array in C++ STL. Submitted by IncludeHelp, on March 01, 2019 C++ STL array::get function templateget function template is used to get the ith elements of an array....
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...
