Q-1. What is array? Explain types of array.
Answer:
Simple variable can store only one value at a time, but if you want to store
more than one value into single variable then C language provide derived data
type array.
Array is collection of elements of the same data type.
Array is one kind of data structure in which we can store multiple values at
time and it is known by a single name.
Each element into array can distinguish with help of index.
There are three types of array in C.

For example if you want to store rollno of single student then simple variable
can be used, but if you want to store rollno of 100 students then there are two
option.
1) One may use 100 variables to store 100 values
2) One may use array with size of 100
Obviously you can say that second option is far better as we just need to
remember only one name of array rather than the 100 name of variables.
Q-2. Explain one dimensional array with example.
Answer:
An array that represent list of items with help of only one index (subscript)
then it is known as one dimensional array.
Syntax:
<Data type> <array name> [<size>];
Here, Data type represent the type of data which we want to store into array.
Array name is the name of array which we want to create.
Size defines the size of array or total number of value that we want to store
into array.
Array can be initialized in two different ways:
1) Compile time initialization
2) Run time initialization
1) Compile Time Initialization:
In this type of initialization elements of array can be initialized at the
time of array declaration.
The values are assigned to each array elements enclosed within braces
and separated by comma.
Syntax:
<Data type> <array name> [<size>] = {value1, value2 … value3};
