c++ how to declare an array 0*n code example
Example 1: array syntax in c++
int foo [] = { 16, 2, 77, 40, 12071 };
Example 2: number of elements in c++ array
#include <iostream>
using std::cout;
int a[] = { 1, 2, 3, 4, 5 };
int counta()
{
return sizeof( a ) / sizeof( a[ 0 ] ); // works, since a[] is an array
}
int countb( int b[] )
{
return sizeof( b ) / sizeof( b[ 0 ] ); // fails, since b[] is a pointer
}
