Operators are the building blocks of any programming language. In C++, we have two main types of operators: arithmetic and comparison. Arithmetic operators are used to perform mathematical operations like addition, subtraction, multiplication, etc., while comparison operators are used to compare values and return boolean results.

Just as in financial calculations where various arithmetic operations are used to calculate profit, loss, interest, etc., in C++, arithmetic operators play the same role but are applicable to a broader range of applications. An example of such an application would be the development of a financial system for tracking transactions.

Let's take a look at both types of operators individually:

1. Arithmetic Operators: These include + (addition), - (subtraction), * (multiplication), / (Division), % (Modulus), ++ (Increment), -- (Decrement). Here's an example utilizing arithmetic operators:

2. Comparison Operators: These include == (Equal to), != (Not equal to), < (Less than), > (Greater than), <= (Less than or equal to), >= (Greater than or equal to). A comparison operator in action would be a simple if-else decision-making statement:

In the same way we apply comparison in the financial world, for example, comparing the efficiency of two investment portfolios, in coding we also apply conditional comparisons to make decisions or control the flow.

#include <iostream>

using namespace std;

int main() {

  // Arithmetic operators

  int x = 10;

  int y = 20;

  cout << "x + y = " << x + y << endl;

  cout << "x - y = " << x - y << endl;

  cout << "x * y = " << x * y << endl;

  cout << "x / y = " << x / y << endl;

​

  // Comparison operator

  if(x > y) {

    cout << "x is greater than y" << endl;

  } else {

    cout << "y is greater than x" << endl;

  }

  return 0;
