在Ｃ++1４中允许使用type deduction用于函数参数和函数返回值
Return Type Deduction in C++11
1 #include <iostream> 2 using namespace std; 3 auto AutoFunctionFromReturn(int parameter) -> int 4 { 5 return parameter; 6 } 7 8 int main() 9 { 10 auto value = AutoFunctionFromReturn(1); 11 cout << value << endl; 12 return 0; 13 }
Deducing return types for C++11 template functions
#include <iostream> using namespace std; template <typename T> auto AutoFunctionFromParameter(T parameter) -> decltype(parameter) { return parameter; } int main() { auto value = AutoFunctionFromParameter(2); cout << value << endl; return 0; }
In order to reduce the verbose code
Using auto to Deduce Return Type on a Template Function C++14
#include <iostream> using namespace std; template <typename T> auto AutoFunctionFromParameter(T parameter) { return parameter; } int main() { auto value = AutoFunctionFromParameter(2); cout << value << endl; return 0; }
