Answer 1

Answers:

A: document.writeln( f[ 6 ] ); (To display the value of the seventh element of array f)

B: for ( var x = 0; x < 5; x++ ){

  g[ x ] = 8;

} (Initialize each of the five elements of one-dimensional array g to 8)

C:

var total = 0;

for ( var x in c ){

total += c[ x ];

} (Total the elements of array c, which contains 100 numeric elements)

D:

for ( var x in a ){

b[ x ] = a[ x ];

} (Copy 11-element array a into the first portion of array b, which contains 34 elements)

E:

function sortNumber( x, y ){

return x - y;

}

w.sort( sortNumber );

document.write( "Smallest value: " + w[ 0 ] + "<br />" );
document.write( "Largest value: " + w[ 98 ] + "<br />" );

(Determine and print the smallest and largest values contained in 99-element floating-point array w)
