Exception:
In C++, the exception is an object used to signal the unexpected error occurred during a
- An exception has been thrown when an error has been occurred in a program.
Explanation of Solution
Throw point:
The throw point is a statement which uses the keyword “throw” to throw an exception which occurred while executing the program.
Example:
Consider the following code segment which throws an exception when it receives value “0” for the argument “b”:
//Function "division" is used to divide two integers
double division(int a, int b)
{
//The value of "b" is 0
if (b == 0)
{
//throw point
//throw an exception contains message
throw "ERROR: denominator should not be "0".\n " ;
}
//otherwise, do the division
else
{
//return the result
return static_ cast<double>(a)/b;
}
}
In the above example, the “throw” statement is used to throw a message and the statement is referred as “throw point”.
- After the execution of “throw” statement, the program control will move to another part in the same program.

- Please help me with this , I am stuck ! PLEASE WRITE IT IN C++ Thanks 1) bagUnion: The union of two bags is a new bag containing the combined contents of the original two bags. Design and specify a method union for the ArrayBag that returns as a new bag the union of the bag receiving the call to the method and the bag that is the method's parameter. The method signature (which should appear in the .h file and be implemented in the .cpp file is: ArrayBag<T> bagUnion(const ArrayBag<T> &otherBag) const; This method would be called in main() with: ArrayBag<int> bag1u2 = bag1.bagUnion(bag2); Note that the union of two bags might contain duplicate items. For example, if object x occurs five times in one bag and twice in another, the union of these bags contains x seven times. The union does not affect the contents of the original bags. Here is the main file: #include <cstdlib>#include <iostream>#include "ArrayBag.h"using namespace std; template…arrow_forwardMethod Overloading is a feature that allows a class to have two or more methods having same name, if their argument lists are different. Argument lists could differ in: 1. Number of parameters. 2. Data type of parameters. 3. Sequence of Data type of parameters. Write different version of method sum() that display the sum of the values received as parameter according to the following main method content: public static void main(String[] args) { sum ( 10, 10 ); sum ( 10, 10, 10 ); sum ( 10.0, 10.0 ); sum ( 10, 10.0 ); sum ( 10.0, 10); } You have to define five functions with the specified types. Then, demonstrate the Argument Promotion concept by reducing the number of method to two.arrow_forwardMethod overloading: given the following methods, write down the printed output of the method calls.arrow_forward
- Code in C# (OOP Concept) Do a program that does the following: Ask for a number from the user in the main method o Pass thenumber to a method call it "Multiplication”. In the Method Multiplication, multiply the number by a number enteredby the user (mention that the number should be positive). Send the result back to the main and print it from the mainModify the previous program if the user enters a negative second number in the method Multiplication, do not acceptthe number and ask the user to reenter it again. . Add another method call it also Multiplication Ask for a float numberfrom the main and send it to the new Multiplication. This method should also ask for another positive number fromthe user and multiply it by the float number. Design and implement a function called "multiply" in C++ that accepttwo numbers and returns either the arithmetic multiplication or repetition of a given string a specific number of timesdepending on the data types of the argument values.

- Solution Floating point representation: It is defined as the representation of floating numbers. It includes sign bit, exponent, and mantissa bits. Based on precision it has 2 types. 1. For IEEE 754 single-precision floating-point numbers, what is the exponent of a denormalized floating-point number in decimal? Solution: In IEEE 754 single-precision, exponent bits are 8. Therefore exponent = 2 ^(n-1) -1 = 2^(8-1) -1 = 127 OPTION D 2. For IEEE 754 single-precision floating-point numbers, how many bits for mantissa? Solution: In IEEE 754 single-precision, there are 23 bits for mantissa. sign = 1 bit exponent = 8 bits mantissa = 23 bits 3. For IEEE 754 single-precision floating-point numbers, which of the following is an example of NAN? Solution: In IEEE 754 single-precision, NAN is a special value where all exponents bits are 1's and the mantissa is non zero. a. 1 111 1 111 0000 0000 1101 0000 0000 0000 Exponent is not all 1's.
