Initializing multidimensional arrays one by one

Demo Code

#include <iostream> 
using namespace std; 

void printArray( const int [][ 3 ] ); // prototype 
const int rows = 2; 
const int columns = 3; 

int main() //from   ww  w  . ja  v a2s.  c  om
{ 
    int array1[ rows ][ columns ] = { { 1, 2, 3 }, { 4, 5, 6 } }; 
    int array2[ rows ][ columns ] = { 1, 2, 3, 4, 5 }; 
    int array3[ rows ][ columns ] = { { 1, 2 }, { 4 } }; 

    cout << "Values in array1 by row are:" << endl; 
    printArray( array1 ); 

    cout << "\nValues in array2 by row are:" << endl; 
    printArray( array2 ); 

    cout << "\nValues in array3 by row are:" << endl; 
    printArray( array3 ); 
}

void printArray( const int a[][ columns ] ) 
{ 
    // loop through array's rows 
    for ( int i = 0; i < rows ; ++i ) 
    { 
       // loop through columns of current row 
       for ( int j = 0; j < columns; ++j ) 
           cout << a[ i ][ j ] << ' '; 

       cout << endl; // start new line of output 
    }
}
