length of int

[sreeram_r]

I'M A NEW PROGRAMMER IN C++.I WANT TO KNOW HOW TO FIND THE LENGTH OF A INTEGER ARRAY IN C++..
THANK U..

Hmm. You're at the wrong forum my friend.

But well, I assume you have defined an array like this:

int array [NR_OF_ELEMENTS];

The size of an int can be calculated using sizeof () operator:

int_size = sizeof (int);

And then the size of the array can be calculated like this:

array_size = int_size * NR_OF_ELEMENTS;

[Andreas Masur]

Well, the short form would be...

int array[NR_OF_ELEMENTS];

int array_size = sizeof(array);




Ciao, Andreas
