Intializing a Boolean Array [Solved]

I get this error

Code:
error C2440: 'initializing' : cannot convert from 'bool' to 'bool [3]'

when i do this

Code:
bool flag[3] = true;

How do i make them all true?

[highlight=vb]bool flag[3];
for(int i =0;i<3;i++)
{
flag[i]=true;
}[/highlight]

or[highlight=vb]bool flag[3] = {true, true, true};
[/highlight]

Yeah, do it 1000 times to initialize 1000 items ?

It's 3, not 1000...
In this case it could be what I posted

I am sure he does know how to initialize an array of 3 items. Look at this thread: http://www.mpgh.net/forum/31-c-c-pro...ter-array.html

I think he was just using [3] as an example to see how all can be initialized to true.

Oh okay.
I thought he needed an array of 3.

Hey Hassan, could u tell me if this is right? i want a better understanding of arrays. does an array start with 0 or 1?

if bool [3] = {true, true, true};

would it be listed like this?

a)
bool [0] = true;
bool [1] = true;
bool [2] = true;

or

b)

bool[1] = true;
bool[2] = true;
bool[3] = true;

An array starts with 0. So, the following would create an array containing 3 elements:

[highlight=vb]bool myArray[3];[/highlight]

As arrays are zero-based, the first element of the array can be accessed by:

[highlight=vb]myArray[0];[/highlight]

and the last element is accessed as:

[highlight=vb]myArray[2];[/highlight]

So, (a) is correct.
