“通常c++编译器并不为const创建存储空间“，可以举个例子么？

Question

是这样么？如果真的存在，可以举个例子么？

Answer 1

Usually

const c = 10;
a = c;

The compiler compiles directly into

mov [a],10

instead of

mov AX,[c]
mov [a],AX

Answer 2

Because const modifies a read-only variable, an initial value must be assigned when defining it. This initial value is usually a literal. The compiler will put this literal into the read-only data segment, so the variable does not need to be used during the compilation phase. Storage space, just note it in the symbol table
