Introduction to Parameterized Functions:<\/strong><\/p>\n\n\n\n

A parameterized function<\/strong> in C++ is a function that accepts one or more arguments, which are used within the function to perform a specific task. The primary advantage of parameterized functions is their flexibility. By passing different values to the parameters, the same function can be used to perform various operations, making your code reusable and more concise.<\/p>\n\n\n\n

Code Example: Simple Calculator Class with Parameterized Functions<\/h3>\n\n\n\n
#include <iostream>
using namespace std;

class Calculator {
private:
    int a; \/\/ Attributes of the class
    int b;

public:
    \/\/ Method for sum
    int sum(int a, int b) {
        return a + b;
    }

    \/\/ Method for subtraction
    int subtract(int a, int b) {
        return a - b;
    }

    \/\/ Method for multiplication
    int multiply(int a, int b) {
        return a * b;
    }
};

int main() {
    \/\/ Creating an instance of the Calculator class
    Calculator calc;

    \/\/ Calling methods and printing the results
    cout << \"Sum: \" << calc.sum(10, 5) << endl;
    cout << \"Subtraction: \" << calc.subtract(10, 5) << endl;
    cout << \"Multiplication: \" << calc.multiply(10, 5) << endl;

    return 0;
}
