This code find maximum or largest element present in an array. It also prints the location or index at which maximum element occurs in array. This can also be done by using pointers (see both codes).
Wires are made of metal (almost always copper or aluminum, for electrical wires) because those are the best conductors. The internal components of switches are also made of metal, for the same reason. The outside parts, that you touch and see, are...
Some materials let electricity pass through them easily. These materials are known as electrical conductors. Many metals, such as copper, iron and steel, are good electrical conductors. That is why the parts of electrical objects that need to let electricity pass through are always made of metal.
