There is a safety concern if the vehicle experiences a malfunction or encounters a red light or police; just operate your own vehicle instead.
Answer:
#include <iostream>
using namespace std;
class Digits
{
public:
int num;
int read() //method to read num from user
{
cout<<"Enter number(>0)\n";
cin>>num;
return num;
}
int digit_count(int num) //method to count number of digits of num
{
int count=0;
while(num>0) //loop till num>0
{
num/=10;
count++; //counter which counts number of digits
}
return count;
}
int countDigits(int num) //method to return remainder
{
int c=digit_count(num); //calls method inside method
return num%c;
}
};
int main()
{
Digits d; //object of class Digits is created
int number=d.read(); //num is read from user
cout<<"\nRemainder is: "<<d.countDigits(number); //used to find remainder
return 0;
}
Output:
Enter number(>0)
343
Remainder is: 1
Explanation:
The program has a logical error that needs rectification. A correctly structured program calculates the remainder when a number is divided by the count of its digits. A class named Digits is created, consisting of the public variable 'num' and methods for reading input, counting digits, and calculating the remainder.
- read() - This function asks the user to enter the value for 'num' and returns it.
- digit_count() - This function accepts an integer and counts how many digits it has, incrementing a counter until 'num' is less than or equal to 0. It ultimately returns the digit count.
- countDigits() - This function takes an integer and delivers the remainder from dividing that number by its digit count. The digit count is computed using the 'digit_count()' method.
Finally, in the main function, a Digits object is instantiated, and its methods are utilized to produce an output.
Answer:
public class PostAccount
{
public void withdraw(float savings)
{
if (savings >=0 )
{
IllegalArgumentException exception
= new IllegalArgumentException("Savings cannot be negative");
throw exception;
}
balance = savings - withdraw;
}
}
Explanation:
An IllegalArgumentException is categorized as a NumberFormatException of runtime exceptions. The code snippet demonstrates an instance of creating an IllegalArgumentException object, which is subsequently raised to indicate when the condition specified is not fulfilled.
