the ls output results. However, some terminals do not support colors, so that all files use the same color, in this case, the-F parameter can be used to differentiate.
-R: recursively lists objects in the parameter subdirectories. That is to say, the subdirectory, the Sun Directory, and all files in the descendant directory will be listed.
-L: this parameter is also useful for common text files. It lists the detailed information of each file in the form of rows, one row for each file, the infor

This program indicates the difference between float and double.

In this example, we can see that a is a single-precision floating point type, and the number of valid digits is only seven. The integer has five digits, so after the decimal two digits, all digits are invalid. B is a dual-precision model with a valid bits of sixteen bits. However, Turbo C requires that a maximum of six

When you do not need to export a Bom, this method is relatively more compliant. However, once you need to export the BOM, you will get a messy Bom. The specific manifestation is that when altiumdesinger exports the BOM, it can only classify components by comment and footprint, rather than by value or other attributes, and divide the components with different value values into different columns for display.
