Key Points

Dowry System:

• Dowry, or the custom of accepting gifts by the bridegroom’s parents from to bride’s parents as part of a marriage settlement.
• Dowry is the money, valuables, goods, estate or property which the bride party gives to the groom's party in exchange for marriage.
• The Dowry system is most prevalent in village areas where people are uneducated and a girl is considered as a burden on their family.
• With upcoming times, this practice is not that common in urban areas.
• To prevent the system of dowry, The Dowry Prohibition Act, 1961 was enacted.
• Section 2 of the Prohibition of Dowry Act defines dowry as any property or valuable security given or agreed to be given either directly or indirectly.
• Dowry is given by one party to a marriage to the other party to the marriage or by the parents of either party to a marriage or by any other person, to either party to the marriage or to any other person.

The correct answer is Copper and Tin.
Key Points

• Bronze
  • Bronze is an alloy traditionally composed of copper and tin.
  • Bronze is of exceptional historical interest and still finds wide applications.
  • It was made before 3000 BC, though its use in artifacts did not become common until much later.
  • The proportions of copper and tin varied widely (from 67 to 95 percent copper in surviving artifacts), but, by the Middle Ages in Europe, certain proportions were known to yield specific properties.
  • An alloy described in an 11th-century Greek manuscript in the library of St. Mark’s, Venice, cites a proportion of one pound copper to two ounces of tin (8 to 1), approximately that used for bronze gunmetal in later times.
  • Some modern bronzes contain no tin at all, substituting other metals such as aluminum, manganese, and even zinc.

Additional Information

• Copper and Silver
  • The best-known copper-silver alloy is sterling, which is 92.5 percent silver and 7.5 percent copper.
  • In England sterling, silver is traditionally identified by the hallmark of a lion passant.
  • Coin silver is an alloy of 90 percent silver and 10 percent copper.
  • For jewelry and ornaments, 85–90 percent silver (and the balance copper) is frequently used.
  • Dental alloys of 60–70 percent silver, 18–25 percent tin, 2–14 percent copper, and 0.5–2 percent zinc are amalgamated with varying quantities of mercury to form the filling materials for cavities in teeth.
• Copper and zinc
  • Brass is an alloy of copper and zinc, of historical and enduring importance because of its hardness and workability.
  • The earliest brass was called calamine brass, which dates to Neolithic times.
  • It was probably made by the reduction of mixtures of zinc ores and copper ores.
  • In ancient documents, such as the Bible, the term brass is often used to denote bronze, the alloy of copper with tin.
• Copper and Lead
  • Leaded bronzes contain from 4 to 25 percent lead plus additions of copper and tin, and some copper-lead bearing alloys contain up to 40 percent lead.
  • All these bearing alloys are sufficiently soft so that lubrication failure does not result in damage to the bearing.
  • Lead-based bearing alloys are also known as lead-based babbitt metals or white metals.
  • These are usually antimonial lead with widely variable additions of tin or copper (or both) and arsenic to increase strength.
  • One such alloy is commonly used for railroad-car journal bearings, contains 86 percent lead, 9 percent antimony, and 5 percent tin.
  • Many alloys of lead and alkaline-earth metals, such as calcium and sodium, also are widely used as bearing materials.

The correct answer is Three.

According to the Dowry Prohibition Act, 1961, 3 conditions related to dowry have been stated.

Key Points

Dowry Prohibition Act, 1961

  • The third is at any time after the marriage. The third occasion may appear to be an unending period. But the crucial words are in connection with the marriage of the said parties.

Void pointer: It is a specific pointer type – void * – a pointer that points to some data location in storage, which doesn’t have any specific type. Void refers to the type.

• void pointers cannot be dereferenced. It can however be done using typecasting the void pointer
• Pointer arithmetic is not possible on pointers of void due to lack of concrete value and thus size

Other Important Points

Dangling pointer: A pointer pointing to a memory location that has been deleted (or freed) is called dangling pointer.   

Uninitialized pointer : An uninitialized pointer stores an undefined value. A null pointer stores a defined value, but one that is defined by the environment to not be a valid address for any member or object.

NULL Pointer : NULL Pointer is a pointer which is pointing to nothing. In case, if we don’t have address to be assigned to a pointer
