Technical Forum to Ask, Learn, & Collaborate

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

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
