std::function

Question

Is std::function an alternative for the normal way of writing a function(if it is, which is better?) . I've seen it on Google but got me confused 😕

Answer 1

std::function lets you use a function like a variable, an alternative to function pointers. It is in some cases the only way to store a lambda.

std::function is not a function, but a way to store an existed function.

Answer 2

//So it will be an alt for this?
#include <iostream>
using namespace std;

int add(int a, int b){

return a + b;
}

int main() {

int(*funct_ptr)(int,int);
funct_ptr = add;

int sum = funct_ptr(5,5);
cout << sum;

return 0;

Answer 3

Yes

Answer 4

ChillPill thanks it worked perfectly! Note that <functional> should be included. Also is there any reason to use it instead of function pointer?
Thanks again for all <3
