Thread: Arrays & Classes

Hi!I want to use an array as a class member.I wrote something like this:

Code:

class my_class{
      
         public:
                  ....
                  int x;
                  int array[5];
                  void function();          
                   .....
         }

my_class::my_class()
{
        ....
         x = 0;
         array[ 5 ] = { 0,1,2,3,4 };
}

void my_class::function()
{
     for( i = 0; i < 5; i++ )
     {
           if ((something) > array[i] )
           {
                 do something.....;
            }
      }
}

The compiler (Dev-C++) gave an error with the message "expected priimary - expression before '{' token : in the line // array[ 5 ] = { 0,1,2,3,4 }; // of the constructor.

Any ideas...?

========

thou shalt not initialize variables inside of a class.. that is the sole responsibility of the class constructor.

Code:

 x = 0;    <- not allowed inside a class
array[ 5 ] = { 0,1,2,3,4 };    <- not allowed inside a class

array[5] does not exist... array's are 0-based so valid indicies go from 0 up to and including 4 (but not 5). In addition, array[5], if it existed, would be a single element of the array to which you are attempting to assign 5 integers. I'd suggest a loop:

Code:

my_class::my_class()
{
    ....
    x = 0;
    for( int i = 0; i < 5; ++i )
        array[ i ] = i;
}

youre missing a semicolon after the class declaration

>>that is the sole responsibility of the class constructor.
it is in the constructor

Just wondering - It is C++ why not to use vector?
