Question

write in c++
 Create a program that uses EXCEPTION HANDLING to deal with an invalid input entry
    by a user.
    
    a.  Write a program that prompts a user to enter a length in feet and inches.  The length values
        must be positive integers.
    
    b.  Calculate and output the equivalent measurement in centimeters
    
        1 inch = 2.54 centimeters
        
    c.  Write the code to handle the following exceptions:

        If the user enters a negative number, throw and catch an error that gives the user the appropriate
        message and request a valid number.  Do this until the user enters a valid number

        If the user enters a character, throw and catch an error that indicates the input stream
        is invalid.  Write code that resets the input stream and request a valid number.  Do this
        until the user enters a valid number
        
    d.  Output the feet-inch input values to centimeter conversion value

Answer 1

Here is code:

#include <iostream>

#include <limits>

#define CENTIMETER 2.54

using namespace std;

int getInches(int low)

{

int num;

// check if input is valid or not

if (!(cin >> num) || (num <= low))

{

// flush the cin data

cin.clear();

cin.ignore(numeric_limits<streamsize>::max(), '\n');

throw "The number is out of bounds: Try again : ";

}

return num;

}

int main()

{

int inches = 0;

cout << "Enter a length in feet and inches : ";

while (1)

{

try

{

inches = getInches(0);

cout << "Feet-inch input values to centimeter conversion value : " << (inches * CENTIMETER) << endl;

break;

}

catch (const char *str)

{

cout << str;

}

}

// Number validation

return 0;

}

Output:
