What output does this program generate as shown? Why?
class A {
A() { cout << "A::A()" << endl; }
~A() { cout << "A::~A()" << endl; throw "A::exception"; }
};
class B {
B() { cout << "B::B()" << endl; throw "B::exception"; }
~B() { cout << "B::~B()"; }
};
int main(int, char**)
{
try
{
cout << "Entering try...catch block" << endl;
A objectA;
B objectB;
cout << "Exiting try...catch block" << endl;
}
catch (char* ex)
{
cout << ex << endl;
}
return 0;
}

The program will throw an exception 'A::exception' when trying to construct objectA, since the constructor of A throws an exception. The catch block in main() will catch and print the exception message.

Ask the user to input three positive integers M, N and q. Make the 2 dimensional array of integers with size MxN, where all the elements of I (I = 1,…,M) line will be members of geometrical progression with first element equal to the number of line (I) and denominator q.
Given a table of the form: Product Sold on A 1/1/1980 B 1/1/1980 C 1/1/1980 A 1/1/1980 B 1/1/1980 C 2/1/1980 A 2/1/1980 There are 30 products and 10,000 records of such type. Also the month period during which sales happened is given to u. Write the program to display the result as: Product Month No. of copies A January 12 A February 15 A March 27 B January 54 B February 15 B March 10 C January 37
Write a program that takes a 3 digit number n and finds out whether the number 2^n + 1 is prime, or if it is not prime find out its factors.
What output does the following code generate? Why? What output does it generate if you make A::Foo() a pure virtual function? class A { A() { this->Foo(); } virtual void Foo() { cout << "A::Foo()" << endl; } }; class B : public A { B() { this->Foo(); } virtual void Foo() { cout << "A::Foo()" << endl; } }; int main(int, char**) { A objectA; B objectB; return 0; }
write a program that can LOCATE and INSERT elements in array using c++ programming languages.
Definition of priority queue was given. We have to implement the priority queue using array of pointers with the priorities given in the range 1..n. The array could be accessed using the variable top. The list corresponding to the array elements contains the items having the priority as the array index. Adding an item would require changing the value of top if it has higher priority than top. Extracting an item would require deleting the first element from the corresponding queue. The following class was given: class PriorityQueue { int *Data[100]; int top; public: void put(int item, int priority); // inserts the item with the given priority. int get(int priority); // extract the element with the given priority. int count(); // returns the total elements in the priority queue. int isEmpty(); // check whether the priority queue is empty or not. }; We had to implement all these class functions.

An array of size 5X5 is given to us. The elements from 1 to 25 are to be inserted in the array, such that starting from a particular position for an element i, the next element i+1can be inserted only at the mentioned positions (u,v), and if these all positions are occupied then it returns giving a count of how many positions have been occupied in the array: (u,v) = (x+/-3 , y) (u,v) = (x , y+/-3) (u,v) = (x+/-2 , y+/-2). Example: if the starting element is 1 with the given positions (1,2), then next element 2 can be placed at any one of the positions marked with *. _ _ _ _ _ 1 _ _ _ * _ _ _ _ _ _ _ * _ _ * _ _ _ _
write a function -oriented program that generates the Fibonacci, the current numbers of n(as input) and display them (series). In Fibonacci, the current third number is the sum of the previous number.
Here's the programm code: int magic(int a, int b) { return b == 0 ? a : magic(b, a % b); } int main() { int a, b; scanf("%d%d", &a, &b); printf("%d\n", magic(a, b)); return 0; } on input stream we have integers 4, 45 What's the output integer? How many times will be initiated "magic" function?
write a c program, using for loop, that accepts and odds two numbers. The output must be the sum and the addens. This should be repeated 5 times while the first number is decremented by one and the second number is incremented by 1.
