The C++14 standard made several enhancements to the language to make it more efficient and easier to use.

One of the biggest improvements that come with the C++14 update is the introduction of generic lambdas. In earlier versions of C++, lambdas had been there, but they had limitations. In C++14, these lambdas are allowed to have 'auto' type parameters, making them generic and capable of accepting arguments of any type.

For example, the following is a simple generic lambda that accepts two parameters of any data type and returns the sum:

In AI and finance projects, where mathematical computations and algorithm efficiency are of paramount importance, such enhancements matter a lot.

There are other several minor improvements and features introduced in C++14. Among such, return type deduction for normal functions was a welcome addition. Before C++14, 'auto' was limited to lambda expressions, but with C++14, 'auto' could now be used to deduce the return type of all functions, increasing code flexibility and maintainability.

In the next, we'll dive into examples of using these features and enhancements in code.

#include <iostream>

using namespace std;

​

int main() {

    auto add = [](auto x, auto y) { return x + y; };

    cout << add(10, 5) << endl;     // outputs: 15

    cout << add(2.5, 3.5) << endl;   // outputs: 6.0
