How to use block quotes in Apple Notes Oct 12, 2023 pm 11:49 PM

In iOS 17 and macOS Sonoma, Apple has added new formatting options for Apple Notes, including block quotes and a new Monostyle style. Here's how to use them. With additional formatting options in Apple Notes, you can now add block quotes to your notes. The block quote format makes it easy to visually offset sections of writing using the quote bar to the left of the text. Just tap/click the "Aa" format button and select the block quote option before typing or when you are on the line you want to convert to a block quote. This option applies to all text types, style options, and lists, including checklists. In the same Format menu you can find the new Single Style option. This is a revision of the previous "equal-width"

C++ compilation error: undefined reference, how to solve it? Aug 21, 2023 pm 08:52 PM

C++ is a popular programming language, but during use, the compilation error "undefined reference" often occurs, which brings a lot of trouble to program development. This article will discuss the solution to the "undefined reference" error from both the cause and the solution. 1. Cause of error When the C++ compiler compiles a source file, it will be divided into two stages: the compilation stage and the link stage. The compilation phase converts the source code in the source files into assembly code, while the linking phase combines different source files into an executable file.

What are the benefits of C++ functions returning reference types? Apr 20, 2024 pm 09:12 PM

The benefits of functions returning reference types in C++ include: Performance improvements: Passing by reference avoids object copying, thus saving memory and time. Direct modification: The caller can directly modify the returned reference object without reassigning it. Code simplicity: Passing by reference simplifies the code and requires no additional assignment operations.

How to use C++ reference and pointer parameter passing? Apr 12, 2024 pm 10:21 PM

References and pointers in C++ are both methods of passing function parameters, but there are differences. A reference is an alias for a variable. Modifying the reference will modify the original variable, while the pointer stores the address of the variable. Modifying the pointer value will not modify the original variable. When choosing to use a reference or a pointer, you need to consider factors such as whether the original variable needs to be modified, whether a null value needs to be passed, and performance considerations.

C++ syntax error: When a function returns a pointer or reference, it cannot return a local variable or temporary object. What should I do? Aug 22, 2023 am 09:22 AM

C++ is an object-oriented programming language, and its flexibility and power often provide programmers with great help. However, precisely because of its flexibility, it is difficult to avoid various small errors when programming. One of the most common mistakes is that when a function returns a pointer or reference, it cannot return a local variable or temporary object. So how to deal with this problem? This article will introduce the relevant content in detail. The cause of the problem is that in the C++ language, local variables and temporary objects are dynamically allocated during the running of the function. When the function ends, these local variables and temporary

In-depth analysis of pointers and references in C++ to optimize memory usage Jun 02, 2024 pm 07:50 PM

By using pointers and references, memory usage in C++ can be optimized: Pointers: store addresses of other variables and can point to different variables, saving memory, but may generate wild pointers. Reference: Aliased to another variable, always points to the same variable, does not generate wild pointers, and is suitable for function parameters. Optimizing memory usage can improve code efficiency and performance by avoiding unnecessary copies, reducing memory allocations, and saving space.

Things to note when passing C++ function constant reference parameters Apr 21, 2024 am 08:30 AM

Constant reference parameter passing ensures parameter immutability within a function and has the following advantages: Parameter immutability: A function cannot modify constant reference parameters. Improved efficiency: no need to create copies of parameters. Error detection: Attempting to modify a constant reference parameter triggers a compile-time error.
