Int a [5] = {1, 2, 3, 4, 5}; printf ("% d \ n", * (int *) (& a + 1)-2 );, printf % d What is the result of a certain convincing pen question in a certain year? The answer is 4. Why? My understanding (do not know if it is correct ): & A is an

As for the realization of printf, I must have seen a lot of basic knowledge from the partners who have read the articles I have published before. OK, then not much to say, directly on the source code, to see a simple way to achieve:#include #define

Your understanding is not necessarily correct. It is for reference only. Do not copy it! The same is the same. Lab 1 [Experiment Name]: concurrent program design (experiment 1) [Objective]: to learn how to create a process in a program, observe and

C two-dimensional array (pointer) dynamic allocation and release is preceded by a clear concept:The so-called 32-bit processor can only handle 32 bits at a time, that is, 4 bytes of data, and the 64-bit processor can handle 64 bits at a time, that

When I was reviewing the soft exam, I was going to extend it and thoroughly split the array name and pointer. As a result, the code I wrote completely fainted myself...Code: # Include "stdio. H" Int fun1 (int *) { Int * P = (int *) (& A + 1 );
