C++ try catch

C++ try catch with Explanations

#include <iostream>

int main() {
    try {
        int a = 10;
        int b = 0;
        if (b == 0) {
            throw "Division by zero error";
        }
        int result = a / b;
        std::cout << "Result: " << result << std::endl;
    }
    catch (const char* message) {
        std::cout << "Exception caught: " << message << std::endl;
    }
    return 0;
}

• Explanation:
• The try block is used to enclose the code that may throw an exception.
• Inside the try block, two integer variables a and b are declared with values 10 and 0, respectively.
• An if statement checks if b is equal to 0, and if true, it throws a string "Division by zero error" using the throw keyword.
• If no exception is thrown, the result of the division a / b is calculated and printed to the console.
• The catch block is used to handle the exception. It catches an exception of type const char* (a string) and prints the message to the console.

This program demonstrates the use of try and catch blocks in C++ to handle exceptions that may occur during the execution of the code within the try block. If an exception is thrown, the program jumps to the corresponding catch block to handle the exception.
