Hey, is this constant assignment, please

Can the

Only after x assignment as I could

CodePudding user response:

The

reference 1 floor? Victor.?? Response:

hey, is this constant assignment, please

Can the

Only after x can no longer assignment

that it can realize variable length arrays, int arr [x];

CodePudding user response:

Of course can't

They are not the same thing

Variable-length array should only apply to dynamic

CodePudding user response:

The

reference 3 floor? Victor.?? Response:

of course can't

They are not the same thing

Variable-length array should only apply to dynamic

but I remember the length of the array can be a symbolic constant

CodePudding user response:

Const int x=5;

Int a [x];

This is possible, or the equivalent of int a [5], and no longer realize

But the int a;

Cin> a;

Const int x=a;

Int arr [x]

You can't

Of course,

The compiler version, standard

May have a deviation

But most should still won't do

CodePudding user response:
