Article Introduction：For the convenience of demonstration, create the following Excel table and generate an embedded histogram. Double-click the column and the data series format will pop up. The data label is set to the value. After setting, the value will be displayed on the icon. Double-click the data label to pop up the data label format. Set as follows: The label is inside the mark, and the display effect is as follows. The label value is a number, and the mark refers to the column. This is the effect of the label being centered. This is the effect of the label being inside the axis. This is the effect of the label being outside the data mark. Note that the label refers to the number, and the mark Refers to the column.

Article Introduction：The end mark of the string is "'\0'". In order to determine the actual length of a string, C++ specifies a "string end flag", represented by the character "'\0'"; in programs, we often rely on detecting the position of "'\0'" to determine whether the string ends. Rather than determining the string length based on the length of the array.

Article Introduction：Bit stuffing is a technique used in data communications systems to detect and correct errors that may occur during data transmission. It works by adding extra bits to the data being transmitted to flag errors when they occur. A common way to implement bit stuffing in Java is to use a flag byte (like 0x7E) to indicate the start and end of a frame, and a special escape byte (like 0x7D) to indicate that the next frame byte is a padding Bit. For example, the sender will add a padding bit before each occurrence of the flag byte in the sent data so that the flag byte is not mistaken for the beginning or end of the frame at the receiver. Here is an example of how to implement bit stuffing in Java - publicstaticbyte[

Article Introduction：Full-text databases mainly include electronic books, electronic magazines, electronic newspapers, etc. The full-text database eliminates the need for document indexing and other processing steps, and reduces human factors in data organization. Therefore, the data is updated quickly and the accuracy of search results is higher. At the same time, since the full text is directly provided, it saves the trouble of finding the original text. , so it is deeply loved by users.
