Help Needed: How can I pass a function to a class constructor and then store it as some class variable?
By parveen1981, history, 5 years ago, In English

Hello guys, I wanted to ask if there is any way such that I can pass a function to the constructor of the class and then store it as some variable so that I can execute it later.

Thanks in advance.

Hi parveen. Hope this helps.

class functionsetter {

public: 

int (*function_name)(int ,int);
functionsetter(int (*f1)(int,int)):function_name(f1)
{

}

};

int add(int x,int y) { return x+y; }

int main() {

functionsetter f1(add); int x = f1.function_name(3,5); cout<<x<<"\n"; }
