Given variables grade, region, and amount, declare and assign the following pointers:

character pointer gradePointer is assigned with the address of grade.

integer pointer regionPointer is assigned with the address of region.

double pointer amountPointer is assigned with the address of amount.

Ex: If the input is B 3 1000.0, then the output is:

Oil grade: B Region of import: 3 Quantity: 1000.0

#include #include using namespace std;

int main() { char grade; int region; double amount; /* Your code goes here */ cin >> grade; cin >> region; cin >> amount;

cout << "Oil grade: " << *gradePointer << endl; cout << "Region of import: " << *regionPointer << endl; cout << "Quantity: " << fixed << setprecision(1) << *amountPointer << endl;

return 0; }

c++ and please please make it correct
