编译器一般构成 传统的编译器通常分为三个部分,前端(frontEnd),优化器(Optimizer)和后端(backEnd). 在编译过程中,前端主要负责词法和语法分析,将源代码转化为抽象语法树;优化器则是在前端的基础上,对得到的中间代码进行优化,使代码更加高效;后端则是将已经优化的中间代码转化为针对各自平台的机器代码。 GCC GCC(GNU...

This is consistent with pointer addition where the number added is the pointer’s data type size. We use “unit” as the operand. In the following example, we declare an array and pointers to the array’s elements. We then take their difference: int vector[] = {28, 41, 7}; int *p...
