Using std::bind and std::function in C++

`std::bind` and `std::function` enhance function flexibility. `std::function` can store any callable object. `std::bind` allows you to bind arguments to functions. Here’s an example:

```#include 
#include 
using namespace std;
void greet(string name) { 
       cout << "Hello, " << name << endl; 
} 
int main() { 
    auto boundGreet = bind(greet, "Alice"); 
     boundGreet(); // Outputs Hello, Alice return 0; 
} ``` 

In this code, `std::bind` simplifies function calls with parameters. These tools improve code clarity and maintainability.
