Abstract: This article mainly introduces several file merging, address determination, symbolic parsing and relocation related problems in static links, taking the GCC compiler as an example.first, when the linker links multiple files, how do you

The time complexity of the heap sorting algorithm is O (NLGN), which is better than the insertion sort, but not the same as the merge sort, where the heap sort does not require additional storage space, or, in other words, requires only a constant

1. Why do the red and black trees perform rotation operationsCause: Red and black trees when performing insert and delete operations on a two-fork search tree, the result may violate the nature of the red-black tree, changing the color and pointer

1 declarative: The so-called declarative is to tell the compiler the name and type of something, but ignore the details. The following are the declarative expressions:extern int x; // remember: The declaration of the variable plus

After the analysis of the first two articles, to tell the truth, now I am more dizzy. But still adhere to their own learning methods, first of their own "natural" understanding, and then to verify the official statement. After all, the things are
