You can use the -std=c2x or -std=gnu2x command-line options to enable C2X features. The default C dialect in GCC 13 is -std=gnu17. If you’re interested in the C++ language and what's supported in recent GCC releases, check out New C++ features in GCC 10 and New C++ features in GCC 12. This article describes new features implemented in the C front end it does not discuss developments in the C language itself. It also doesn’t cover recent changes in the C library itself. It's also possible to try GCC 13 on and similar pages. Red Hat Enterprise Linux (RHEL) users will get GCC 13 in the Red Hat GCC Toolset (RHEL 8 and RHEL 9). GCC 13 is already the system compiler in Fedora 38. Like every major GCC release, this version will bring many additions, improvements, bug fixes, and new features. This keeps going until either all conditions are false, which means the grade’s value will be A, or until one of the conditions is evaluated to be true and its truthy value is assigned to grade.The latest major version of the GNU Compiler Collection (GCC), 13.1, was released in April 2023. If it’s false, then the second expression is evaluated which is score < 70. If it’s true, then the value of grade is F. The first condition is evaluated, which is score < 50. These same conditions can be performed using ternary operators as follows: let score = '67' let grade = score < 50 ? 'F' : score < 70 ? 'D' : score < 80 ? 'C' : score < 90 ? 'B' : 'A' console. In this code block, you test multiple conditions on the score variable to determine the letter grading of the variable. Checking that the object is actually set first can help you avoid errors.įor example: let book = console. If you try to access a property on an object that’s actually null or undefined, an error will occur. This is especially useful when the variable is an object. Using the ternary operator, you can check that a variable is not null or undefined just by passing the variable name in the position of the condition operand. In many cases, you might be handling variables that may or may not have a defined value - for example, when retrieving results from user input, or when retrieving data from a server.
