Sample output:-

Copy program:-

#include <iostream>

using namespace std;

double *fn1(double n1, double n2) {
double *result = new double;
*result = 1;
return result;
}

double *fn2(double n1, double n2) {
double *result = new double;
*result = 2;
return result;
}

int main() {
double *(*fnPointers[12])(double, double);

fnPointers[0] = fn1;
fnPointers[1] = fn2;

cout << *fnPointers[0](0, 1) << endl;
cout << *fnPointers[1](0, 1) << endl;
return 0;
}
