When a function accepts a variable number of arguments , its prototype cannot provide any information about the number of arguments and type of those variable arguments. Hence the compiler cannot warn about the mismatches. The programmer must make sure that arguments match or must manually insert explicit typecast.

The number of bonds between a pair of atoms is called the bond order.

Bond orders can be calculated from Lewis structures, which are the heart of the valence-bond model. Oxygen, for example, has a bond order of two.

When there is more than one Lewis structure for a molecule, the bond order is an average of these structures. The bond order in sulfur dioxide, for example, is 1.5  the average of an S-O single bond in one Lewis structure and an S=O double bond in the other.

In molecular orbital theory, we calculate bond orders by assuming that two electrons in a bonding molecular orbital contribute one net bond and that two electrons in an antibonding molecular orbital cancel the effect of one bond. We can calculate the bond order in the O₂ molecule by noting that there are eight valence electrons in bonding molecular orbitals and four valence electrons in antibonding molecular orbitals in the electron configuration of this molecule. Thus, the bond order is two.

After the defeat of china by Japan in a war over Korea in 1894,France, Russia, Britain and Germany gave loan to china to help it to the payment of 150 million dollors demanded by japan. These western countries the divided china into spheres of influence, which meant that each country had certain regions of china reserved exclusively for its purposes.

          The united states feared that china would be completely parcelled out in exclusive 'spheres of influence' and that its trade with china would be shut off. The USA, therefore, suggested the policy known as the "Open Door". This policy is also described as "Mee too Policy".

          The division of China into "spheres of influence' has often been described as the "cutting of the Chinese melon".

Sound is a mechanical vibration and needs a medium for propagation. The higher the density of the medium, the faster the sound travels. So, sound cannot travel through vacuum.

As the sound travels faster in solids than liquids and gases, sound travels faster in the glass than Air and water.

A is incorrect. It is acceptable to use assertions to test the arguments of private methods.

B is incorrect. While assertion errors can be caught, Sun discourages you from doing so.
