Question
Create a class Calculator with overloaded methods for addition:A method add(int a, int b) to add two integers.A method add(float a, float b) to add two floating-point numbers.A method add(const std::string& a, const std::string& b) to add two strings representing numbers.A method add(int a, int b, int c) to add three integers.Implement a main program that:Creates an instance of Calculator.Calls the overloaded add methods with different argument types and counts.Displays the results for each addition operation.
Solution
Sure, here is the implementation in C++:
#include <iostream>
#include <string>
class Calculator {
public:
int add(int a, int b) {
return a + b;
}
float add(float a, float b) {
return a + b;
}
std::string add(const std::string& a, const std::string& b) {
return std::to_string(std::stod(a) + std::stod(b));
}
int add(int a, int b, int c) {
return a + b + c;
}
};
int main() {
Calculator calc;
std::cout << "Addition of two integers: " << calc.add(2, 3) << std::endl;
std::cout << "Addition of two floats: " << calc.add(2.5f, 3.5f) << std::endl;
std::cout << "Addition of two strings: " << calc.add("2.5", "3.5") << std::endl;
std::cout << "Addition of three integers: " << calc.add(2, 3, 4) << std::endl;
return 0;
}
This program first defines a Calculator class with four overloaded add methods for different types and counts of arguments. Then in the main function, it creates an instance of Calculator and calls each of the add methods with appropriate arguments. The results of each addition operation are printed to the console.

You must remember that using increment/decrement operatorschanges the original value of a number. Indent your code and include comments for improving the readabilityof your code. Your program should have the following interface.Enter a number : 2020 + 5 = 2520 – 3 = 17(20 + 3)- 2 = 21((20 + 5)*2 / (20 + 3)) = 2Enter a number : 2020 + 5 = 2520 – 3 = 17(20 + 3)- 2 = 21((20 + 5)*2 / (20 + 3)) = 2
Create a C++ programme that accomplishes all arithmetic operations on two complex objects, including addition, subtraction, multiplication, and division. (X + i * Y) represents the Complex Object (Where X and Y are two real numbers and 'i' is an Imaginary). As a programmer, create a class called "COMPLEX" containing the data members X and Y and also getData() and putData() methods to pefrom read and write for the above said Data Members. Define a separate functions for the operations such as Addition, Subtraction, Multiplication, and Division.Input :Read the Two Complex Objects (Each with X and Y)Output :Addition of Two Complex ObjectsSubtraction of Two Complex ObjectsMultiplication of Two Complex ObjectsDivision of Two Complex ObjectsNote :Both X and Y are Non-Negative, otherwise print "Invalid"Define a separate functions with return type and with arguments of two complext objects.
