Why are exceptions so rarely used in C

0 votes
I've been writing in C++ on and off for roughly 5 years; why have I never seen exceptions used for anything other than examples?

Are virtual functions the only way to achieve Runtime Polymorphism in C++?

fprintf is a polymorphism function in the C programming language. It can print to a file, stdout, a printer, a socket, or whatever else the system can represent as a stream if you supply it different handles. FILE* file = fopen("output.txt", "w"); ...READ MORE

Why is Turbo C++ showing this error in DOSBox on my Mac?

Your installation must be defective!  I have a Mac, and I'm typing this on it while using TurboC++.  Consider uninstalling and then reinstalling the programme. Download the package in the same way as you would a.dmg programme from the internet.  (For example, drag and drop the programme into the Applications folder)  Ascertain that your Applications folder is global to your system.  This is what I mean: When in Finder, select the "GO" option from the top menu bar. From the drop down option, choose "Computer." In the newly opened window, click on your hard disc. There is a "Applications" folder there.  That's where you should put TurboC++. Go to Launchpad, and start Turbo C++. ...READ MORE

When and why do I need to use cin.ignore() in C++?

In C++, I developed a simple application that requested the user to enter a number and then a string.  Surprisingly, when I ran the application, it never paused to ask for the string.  It simply ignored it.  After conducting some research on StackOverflow, I discovered that I needed to include the following line: cin.ignore(256, '\n'); before the line with the string input  That addressed the problem and allowed the software to run.  My issue is why C++ need the cin.ignore() line, and how can I forecast when I will need to use it. Here's the software I created: #include <iostream> #include <string> using namespace std; int main() { ...READ MORE

How member functions are implemented in C++?

I read somewhere that member functions in C++ are similar to regular functions but with an additional implicit this parameter. As a result, I assumed that this software would be unable to discriminate between two functions.  However, the software executed successfully.  So, was the above statement incorrect? #include <iostream> class MyCls { ...READ MORE

What does Tokens do and why they need to be created in C++ programming?

Tokenization is essential in determining what a programme does.  What Bjarne is referring to in respect to C++ code is how tokenization rules alter the meaning of a programme.  We need to know what the tokens are and how they are determined.  Specifically, how can we recognise a single token when it comes among other characters, and how should tokens be delimited if  there is ambiguity? Consider the prefix operators ++ and +, for example. Assume we have just one token + to deal with.  What does the following excerpt mean? int i = 1; ++i; Is the above going to apply unary + on i twice with + only? Or will it only increase it once? Naturally, it's vague.  We require an additional token, thus ++ is introduced as its own "word" in the language. But there is now another (though minor) issue.  What if the programmer just wants to use unary + twice without incrementing?  Rules for token processing are required.  So, if we discover that a white space is always used as a token separator, our programmer may write: int i ...READ MORE
