Hi, need help with this code. my professor mentions that we need to use if and switch statements for this code. In not sure if both switch and if statements can be used in the same code. the code below only has if statements. can both switch and if can be used? need help please. I provided pictures of code instructions and how the output/input validation needs to look.   #include <iostream>#include <string>#include <cmath>using namespace std;int main(){//variables and constantsint packageType;double dataUsed;double monthlyCharges = 0.0; // Name of the programcout << "iMobile Bill Calculator ..." << endl; // Display the pacakge options for user to pickwhile (true){cout << "\nSelect a subscription :" << endl;;cout << "\t\t1.
