Use a lambda as a parameter for a C++ function

Question

I would like to use a lambda as a parameter for a C++ function, but I don\'t know which type to specify in the function declaration. What I would like to do is this:

Answer 1

You have 2 ways: make your function template:

template 
void myFunction(F&& lambda){

}

or erase type with std::function

void myFunction(const std::function& f){
    //some things
}
