Exception Handling

Exception handling is a crucial aspect of C++ programming, especially when it comes to engineering solutions for algo trading. Exception handling allows you to gracefully handle and recover from unexpected errors or exceptional conditions that may occur during program execution.

In C++, exceptions are thrown using the throw keyword. You can catch and handle these exceptions using the try and catch blocks. Here's an example that demonstrates how exception handling works:

1#include <iostream>
2using namespace std;
3
4int main() {
5  try {
6    int age;
7    cout << "Enter your age: ";
8    cin >> age;
9
10    if (age < 0) {
11      throw "Age cannot be negative.";
12    }
13
14    cout << "Your age is " << age << endl;
15  }
16  catch (const char* e) {
17    cout << "Exception caught: " << e << endl;
18  }
19
20  return 0;
21}
