Day02 Each writing a small program, first write a note to identify the role and purpose of the program. Important or critical statements are also written in comments. (A very useful habit later) Bytes, which is the smallest unit in the

1. What is byte alignment? Why?In modern computers, memory space is divided by byte. Theoretically, it seems that access to any type of variables can start from any address, however, the actual situation is that access to specific types of variables

Structure alignment in C LanguageStructure alignment in C Language 1, for example: Struct {Short A1;Short A2;Short A3;};Struct {Long A1;Short A2;} B;Sizeof (A) = 6, sizeof (B) = 8. Why?Note: sizeof (short) = 2, sizeof (long) = 4 Because: "member

Java is a strongly typed language, and each variable can only be declared as one type. However, Java and C + + provide "automatic type promotion" and "forced type conversion" to accommodate some of the different data types of "blending operations."
