Exception handling in C++ technology: What impact does exception handling have on program readability?

Exception handling improves the readability of C code because it: separates error handling logic, making the code clearer and easier to understand. Error handling is simplified and a unified method is provided to handle different types of exceptions. Improved code reliability, can handle unrecoverable errors, and prevent unexpected program termination.

Exception handling in C technology: impact on program readability

Exception handling is a C mechanism that Allows programmers to handle runtime errors. When a program encounters an unrecoverable error, it throws an exception, which terminates the program's execution.

Advantages of exception handling

• Improve program readability: Exception handling can improve program readability because it allows Programmers separate error handling code from the main code logic. This makes the code easier to understand and maintain.
• Simplified error handling: Exception handling simplifies error handling by providing a unified method to handle errors. Programmers do not have to write specific error handling code, but code can be categorized based on exception type.
• Improve code reliability: Exception handling can improve code reliability because it allows programmers to handle unrecoverable errors instead of letting the program terminate unexpectedly.

Disadvantages of exception handling

• Performance overhead: Exception handling introduces some performance overhead because the system must Maintain a stack frame for each exception.
• Overuse: Exception handling should not be overused, as misuse of exception handling can make the code difficult to understand.
• Fragile Exception Specifications: Exception specifications define the circumstances under which exceptions are thrown, but they can be fragile because the programmer may forget to specify all possible exceptions.

Practical case

The following is an example of a C program that demonstrates exception handling to improve program readability:

#include <iostream>

using namespace std;

void divide(int a, int b)
{
    try
    {
        if (b == 0)
        {
            throw runtime_error("Division by zero");
        }
        cout << "Result: " << a / b << endl;
    }
    catch (runtime_error& e)
    {
        cout << "Error: " << e.what() << endl;
    }
}

int main()
{
    divide(10, 2);
    divide(10, 0);
    return 0;
}

In this example , exception handling separates the error handling code (runtime_error) from the main code logic, thereby improving the readability of the code.
