What is a function template declaration in C++? A function template declaration in C++ allows you to define a generic function that can operate on different data types. It provides a way to write reusable code by parameterizing the function with one or more generic types. ...
The function is not static. The function is not virtual. The declarator of the function does not contain cv and ref. struct C { void f(this C& self); // OK template<typename Self> void g(this Self&& self); // also OK for templates void p(this C) const; // Error: “const...
A C/C++ declaration: for example, a variable declaration, a type declaration, or a function declaration.This file defines two closely related classes: Declaration and DeclarationEntry. Some declarations do not correspond to a unique location in the source code. For example, a global variable might...

void myFunction(int arg1, double arg2); // 前置声明函数 1.4模板类的前置声明: template <typename T> class MyTemplateClass; // 前置声明一个模板类 1.5命名空间的前置声明: namespace MyNamespace { class MyClass; // 前置声明命名空间中的类 ...
template<parameter-list> function-declaration 1. 函数模板在形式上分为两部分:模板、函数。在函数前面加上template<...>就成为函数模板,因此对函数的各种修饰(inline、constexpr等)需要加在function-declaration上,而不是template前。如 template<typename T> ...
// implement strcmp-like generic compare function // returns 0 if the values are equal, 1 if v1 is larger, -1 if v1 is smaller template <typename T> int compare(const T &v1, const T &v2) { if (v1 < v2) return -1;
There is the one definition rule in C++. So any function with external linkage which is not an inline function or a function template shall be defined only once. However it may be declared several times. For example 1 2 3 4 5 6
