In C++, the ‘==’ operator and the `compare()` member function of the `std::string` class are both used to compare strings, but they have different characteristics and behaviors. Here are the main differences between the two: 1. Syntax Using ‘==’ Operator std::string str1 = “hello”; std::string str2 = “world”; if (str1 == str2) { // strings …
1. Operator Overloading in C++: This involves redefining the behavior of operators (like +, -, *, /, etc.) for user-defined data types (classes or structures). https://images.app.goo.gl/1ce85vWQajVWTXcp9 2. Function Overloading in C++: This allows multiple functions with the same name to be defined, but with different parameter lists. 3. Friend Class and Function in C++: A friend …

C++, a powerful programming language, offers a range of features to enhance code readability, maintainability, and efficiency. Among these features, operator overloading, function overloading, and friend functions play crucial roles in shaping the way we interact with objects and data structures. Operator Overloading in C++ Operator overloading allows you to redefine the meaning of existing …

Here is an easy way to understand explanation of each of the assigned topics, along with example code and clear, simple language that could be helpful when learning. Operator Overloading in C++ What is Operator Overloading? Operator overloading allows us to define how operators (like +, -, *, etc.) work with user-defined types (like classes). …

In this tutorial, we will learn how to multiply two complex numbers in the cpp language. The Complex number consists of the real and imaginary parts. It is expressed in the form of (a+ib). Complex Number Multiplication We will solve this problem by using different methods. Some of them are : Method 1 CODE: Include …
In this tutorial, we will learn how to implement a stack using an array in cpp. A stack is a linear data structure that follows the LIFO (Last In, First Out) principle. This means the last element inserted is the first one to be removed. Operations : PUSH:- This operation is related to inserting an …
Here’s a simple C++ program to check whether a number is even or odd: #include <iostream> using namespace std; int main() { int num; cout << “Enter an integer: “; cin >> num; if (num % 2 == 0) cout << num << ” is even.” << endl; else cout << num << ” is …
Here’s a simple program to add two numb #include <iostream> using namespace std; int main() { // Declare variables int num1, num2, sum; // Ask the user for input cout << “Enter first number: “; cin >> num1; cout << “Enter second number: “; cin >> num2; // Add the numbers sum = num1 + …
Taking a single character input in C++ is #include <iostream> int main() { char input; std::cout << “Enter a single character: “; std::cin >> input; std::cout << “You entered: ” << input << std::endl; return 0; } Output: Enter a single character: a You entered: a In this code: #include <iostream>: This …
