cast to pointer from integer of different size

If the struct member is directly manipulated, it will not take the unexpected valueHowever, alignment issues need to be considered for continuous data formatssuch as data frame formats in communications, such as IP packets, etc.#pragma pack

Today I encountered a pointer array, understanding the channel data for half a day ...BOOLLocalfilesaver::saveadcdata (Cash *data, LPCTSTR folder) { if(_tcscmp (folder, _t ("")) ==0) { return false; } TCHAR Path[max_path]= {0 }; TCHAR

Array pointers (also called row pointers)define INT (*p) [n];() high priority, the first explanation is that p is a pointer to an integer one-dimensional array, the length of the one-dimensional array is n, it can be said that the step of P. In

To assign a two-dimensional array to a pointer, you should assign this value:int a[3][4];int (*p) [4]; The statement defines an array pointer to a one-dimensional array with 4 elements.P=a; Assign the first address of the two-dimensional array to p,

Q: What is C-style conversion? What is Static_cast,dynamic_cast and reinterpret_cast? What's the difference? Why pay attention to it? A: The meaning of a transformation is to change the representation of the variable by changing the type of the

About the C language pointer type cast reference an article:In C, any variable must occupy an address, and the 0-1 code in that address space is the value of the variable. Different data types occupy varying sizes of space, but they all have to have
