Question

Write a height conversion program that shall allow user to convert from feet and inches to meters (option 1) and vice versa (option 2). User shall be able to specify the type of conversion (a menu of two options). Display an error message if an invalid option is specified. Otherwise, the program would read in a length in feet and inches (two separate integer values like 5 and 6) and will output the equivalent length in meters (a double value) or read in a length in meters (a double value) and will output the equivalent length in feet and inches (two separate integer values and inches shall be between 0 and 11). There are 0.3048 meters in a foot, and 12 inches in a foot. For example, if 5 feet and 6 inches are entered for option 1 then the program should output 1.68 meters. On the other hand, if a value of 1.68 meters is entered for option 2 then the program should output 5 feet and 6 inches. You might need to perform casting (type conversion) and possibly rounding for this program to work properly

I have this c++ program that i have to create but i am stuck on it.

Answer 1

Code:

#include <iostream>

using namespace std;
//function to convert feet and inches to meters
void feetInchToMeters(int feet, int inch, double *meter)
{
*meter = feet*0.3048 + (0.3048/12)*inch;
}
//function to convert meters to feet and inches
void metersToFeetInch(int *feet, int *inch, double meter)
{
*feet = meter/0.3048;
*inch = (meter*39.301)-(*feet)*12;//1 meter = 39.301 inches
}

int main()
{
int feet;
int inch;
double meter;
int option;
do{
cout<<"1. Convert feet and inches to meters \n2. Convert meters to feet and inches \n3. Exit"<<endl;
cout<<"Select option :";
cin>>option;
if(option==1)
{
cout<<"Enter the value in feet (integer value) :";
cin>>feet;
cout<<"Enter the value in inches (integer value):";
cin>>inch;
feetInchToMeters(feet, inch, &meter);
cout<<feet<<" feet and "<<inch<<" inches equals to "<<meter<<" meters"<<endl<<endl;
}
else if(option==2)
{
cout<<"Enter the value in meters :";
cin>>meter;
metersToFeetInch(&feet, &inch, meter);
cout<<meter<<" meters equals to "<<feet<<" feet and "<<inch<<" inches"<<endl<<endl;
}
else if(option!=3)
{
cout<<"Invalid option entered"<<endl<<endl;
}
}while(option!=3);
}

Output:
