What is an array - C++ [1/1]

An array is a collective name given to a group of similar quantities. These similar quantities could be aggregate marks of 50 apples, or dollars of 50 humans or their ages.

Various parts of an array

Array needs to be declared, before it is used. In this example, we have used three statements to declare three arrays. The first statement declares a character array of 20 elements. Here char specifies the type of the variable and name specifies the name of the variable. The number 20 specifies the number of elements that can be used with the array name. The number 20 is called the dimension or the size of the array. The other statement declare a float array.
