@文心快码iso c++ forbids variable length array 文心快码 1. 解释什么是变长数组 变长数组(Variable Length Array, VLA)是指在声明数组时,数组的大小不是编译时常量,而是在运行时确定的。这种数组的大小依赖于程序运行时的某些值,比如函数参数、全局变量或者之前计算的结果。 例如,在C语言中,可以这样声明一个变...

Functional modifier The composite element modifier is an additional operator related to C structure field and array accessors. The expression { s \with .id = v } denotes a structure value that is the same as s, except for the field id, which is equal to v. The equivalent expression for...
Although a type-name in the C grammar is actually an abstract type expression, possibly including qualifiers and pointer and array decorators, here we need to distinguish between raw type names (C-type-name) and type expressions (C-type-expr); Fig. 2.3 is adapted from the C grammar to ...
