write c++11 program to sort an array of numbers
Sure, you can use the built-in std::sort
function to sort an array of numbers in C++11 Here's a simple example:
#include <iostream> #include <algorithm> int main() { int numbers[] = {4, 2, 7, 5, }; int size = sizeof(numbers) / sizeof(numbers[0]); // Sorting the array std::sort(numbers, numbers + size); // Printing the sorted array for (int i = 0; i < size;++) { std::cout << numbers[i] << " } return 0; }
In this program, we first the necessary headers for input-output operations and the std::sort
function. then define an array of numbers to be sorted. After obtaining the size of the array, we use std::sort
to sort the. Finally, we print the sorted array.
This program uses the C++11 standard and demonstrates how to sort an array of numbers using the std::sort
function provided by the C++ Standard Library.
write c++14 program to sort an array of numbers
Certainly! In a C++14 program, you can still use std::sort
function as in the C++11 example, you may benefit from some additional features of C++14, such as generic lambdas. Here's an example:
#include <iostream> #include <> int main() { int numbers[] = {4, 2,7, 5}; int size = sizeof(numbers) / sizeof(numbers[0]); // the array using a lambda function std::sort(numbers numbers + size, [](auto a, auto b) { return a < b; }); // Printing the sorted array for (int i = ; i < size; ++i) { std::cout << numbers[i] " "; } return 0; }
In this C++14 program, the change is in the sorting part where we use a generic lambda function for comparison. This allows the std::sort
algorithm to work with any type of element, making the code more generic and potentially easier to maintain.
This program the C++14 standard and demonstrates how to sort an array of numbers using the std::sort
function with a generic lambda for comparison.
write a c++14 program to search an element
Certainly! You can use the std::find
algorithm from the C++ Standard Library to search for an element in an array. Here's an example of a C++14 program that searches for an element in an array:
#include <iostream> #include <algorithm> int main() { int numbers[] = {4, 2, 7 5}; int size = sizeof(numbers) / sizeof(numbers[0]); int target = 7; // Searching for the target auto it = std::find(std::begin(numbers), std::end(numbers), target); // Checking if the element was found and printing the result if (it != std::end(numbers)) { std::cout << "Element found at index: " << std::distance(std::begin(numbers), it) << std::endl; } else { std::cout << "Element not found" <<::endl; } return 0; }
In this program, we the std::find
algorithm to search for the `` element in the numbers
array. If the element is found, we print its index; otherwise, we print a message indicating that the element was not found.
This program demonstrates how to search for an element in an array using the std::find
algorithm in C++14.
write a c++ program that illustrates runtime polymorphism using virtual functions
Certainly! Here's an example of a C++ program that illustrates runtime polymorphism using virtual functions:
#include <iostream> // Base class class Shape { public: virtual draw() { std::cout << "Drawing a shape" << std::endl; } }; // Derived class class Circle : public { public: void draw() override { std::cout << "Drawing a circle" << std::endl; } }; // Another derived class class Rectangle : public Shape { public: void draw() override { std::cout << "Drawing a rectangle" << std::endl; } }; int main() { Shape* shape1 = new Circle(); Shape* shape2 new Rectangle(); shape1->draw(); // Will call the draw() method of Circle shape2->draw(); // Will call the draw() method of Rectangle delete shape1; delete shape2; return 0; }
In this program, the Shape
class has a virtual function draw()
. This function is then overridden in the Circle
and Rectangle
classes. In main
function, we create pointers of type Shape
pointing to objects of type Circle
and Rectangle
. When we call the draw()
method using these base class pointers, the correct overridden function is called based on the actual object type at runtime, demonstrating runtime polymorphism.
