+/*
+*this program is use to find any elemet in any row with variable array size
+*aplication of pointer is use in it
+*important point start from here to:
+*the index value of array can be go to 1 to 100000
+*check till array[1000]
+*end here
+*how to work example:
+**Question:
+***number of array 2
+***quarry 3
+***array 1 is {1 2 3 4 5}
+***array 2 is {6 7}
+****i) what is 2nd element in 1st array
+****ii) what is 1st element in 2nd array
+****iii) what is 5th element in 1st array
+*****output:
+*****Enter Number of array you want to Store : 2
+*****Enter Number of Question or Quary you want to do Related to Array : 3
+*****Enter number of element in 1 rows : 5
+*****Enter the element of Array 1 2 3 4 5
+*****Enter number of element in 2 rows : 2
+*****Enter the element of Array 6 7
+*****enter the number of row which element You want to find : 1
+*****enter the position of element which You want to find : 2
+*****The element is 2
+*****enter the number of row which element You want to find : 2
+*****enter the position of element which You want to find : 1
+*****The element is 6
+*****enter the number of row which element You want to find : 1
+*****enter the position of element which You want to find : 5
+*****The element is 5
