Explanation / Answer

// DEFINE FUNCTION read_us_length HERE

int read_us_length(int & yards, int & feet, int & inches)
{
cout << "Enter number of yards: ";
cin >> yards;

if (yards < 0)
{
cout << "Illegal negative value " << yards << " for yards." << endl;
exit(0);
}

cout << "Enter number of feet: ";
cin >> feet;

if (feet < 0)
{
cout << "Illegal negative value " << feet << " for feet." << endl;
exit(1);
}

cout << "Enter number of inches: ";
cin >> inches;

if (inches < 0)
{
cout << "Illegal negative value " << inches << " for inches." << endl;
exit(2);
}
}

// DEFINE FUNCTION convert2inches HERE:

int convert2inches(int yards, int feet, int inches)
{
int total_inches;
total_inches = yards * 36.0 + feet * 12.0 + inches;
return(total_inches);
}

// DEFINE FUNCTION convert2metric HERE

void convert2metric(const int total_inches, int & meters, int & centimeters)

{

centimeters = total_inches * 2.54;

meters = centimeters/100;

centimeters = centimeters % 100;

}

// DEFINE FUNCTION write_metric_length HERE:

void write_metric_length(const int meters, const int centimeters)

{

cout << "The length is " << meters << " meters and " << centimeters << " centimeters.";
