Question

Write a Program that has a menu with a  layout below, that asks the user if they want to:

1. Converts from feet and inches to meter and centimeters

2. Converts from meter and centimeters to feet and inches

3. Quit the program

The program should continue as long as the user asks it to.

The program will use a switch statement for the menu option selection. Either a do loo or a do-while loop can be used for the overall program operation in main. Make sure your while or do-while statement is a conditional one (for example, while(loop=='y')) to keep looping.

Reminder to not use any global variables except for constants, which should be in caps.

Use a function for menu, the Eng2Metric and Metric2Eng functions which are not required to return not accept and inputs.

For example, the Eng2metric function will ask the user to enter the feet and inches and output the meters in a fraction as in something like 1.45 meters.

       float feet,inches,meter,cm;

       //find feet and incehs
       int feet1 = int(feet);
       double fractionalFoot = feet - feet1;
       inches = fractionalFoot * 12.0;

   feet=feet+(inches/12);
  
   meter=0.305*feet;
   cm=meter*100;
   cout<<"Height is "<<meter<<" meter"<<endl;
  
}
int main()

char ch='y';
int opt;

   menu(opt);
   switch(opt)

       case 1:
           Eng2Metric();
           break;
          
       case 2:
           Metric2Eng();
           break;
       case 3:
           return 0;
           break;
       default:
           cout<<"Wrong option selected\n";

   cout<<"Do you want to continue(y/n): ";
   cin>>ch;

return 0;
