Array in C++.
Array is one of the most useful concept of programming language , let`s talk little bit before starting with array.
Let`s suppose we have one integer type variable named as number1 but that`s not enough for our work then take one more variable named as number2 now we need one more variable to store our numbers come`on take one more variable named as number3. Now stop and think if you need to store 1000 numbers then what would you do? will you declare number variable 1000 times?. I know that your answer is no , for that we need a better solution , and that solution is array. Because an array can contain a list of data in itself.
What is array?
Array is just a collection of similar types of data items, when we need to store the same types of data in a single variable then we create an array and use it to store data. An array should be declare before the use just like other variables.
What is array subscript.
Array subscript is notify the location of each array element in a array. Array subscript is start from 0 and ends on array_size – 1.
What is array element.
Array elements are the data which we stored in a array. Elements of a array always have same data type.
How to declare a array.
Let`s see the syntax of declaring a array in C++.
In above syntax you can see that how to declare a array in C++.
In above example num is a integer type array , which can be store 20 elements.
Types of array in C++.
In C++ there are two types of arrays, are as follows.
