Why the liner search algorithm also called sequential search

Why the liner search algorithm also called \"sequential search\" How do you return a value from function? What is the difference between a size declaration and a subscript? What does each of the following statement display cout

Solution

1) Linear search is also called as Sequential search as It sequentially checks for the target value with each element of the list until a match is found or until all the elements of the list have been searched.

2) We return the value from the function using \"return\" keyword. This should be the last statement of the function.
eg. if the function return value of integer type then the return type of the function should be int.

3) Lets declare an array of 10 integer values.
int[] arr=new int[10];

Subscript :
The first subscript of an array is always zero and the last subscript\'s value is (array_length - 1).
When an array element is referenced/accessed, the subscript expression designates the desired element by its position.
eg.
arr[5]=4;
We designate that 6th element of array arr has value=4.

Size declaration : Within square brackets, we specify the number of elements in the array. The number of elements must be an integer value.
Integer or constant expression for number of elements in the array. in our example 10 is the subscript.

4)
(i) cout<<value[4]<<endl;
Output: It displays the 5th element of the the array \"value\".

(ii) cout<<value[2]+value[4]<<endl;
Output: It adds the 3rd and 5th array element of the array \"value\".

5) cout<<*(number+3)<<endl;
Output : It refers to value stored at index 3 of the array number.
