Why Compiler Writing machine language-numeric codes is time consuming and tedious

Assuming two bytes for integers, four bytes for addresses, one byte for character and eight bytes for double-precision floating point, we would have the following offset values:

Semantic analysis Parsing only verifies that the program consists of tokens arranged in a syntactically-valid combination, we now move on to semantic analysis, where we delve deeper to check whether they form a sensible set of instructions in the programming language

一、声明的语义分析； 二、执行体的语义分析： 三、表达式的语义分析； 四、语句的语义分析；
