Lambda expressions are a powerful feature in C++. They allow you to define anonymous functions. These functions can be defined inline and passed as arguments. Lambda expressions enhance code readability and conciseness. They are especially useful for callbacks and functional programming.
Here’s an example:
“`cpp
#include
using namespace std;
int main() {
auto add = [](int a, int b) { return a + b; };
cout << add(5, 10) << endl; // Outputs 15
return 0;
}
```
In this code, a lambda function is defined to add two numbers. It is invoked immediately after its definition. Lambda expressions provide flexibility in coding styles. They reduce boilerplate code and enhance clarity.
In summary, lambda expressions are a valuable tool in modern C++. They simplify coding and promote more expressive syntax.
