Program Plan Intro
Linear search:
- Linear search or sequential search is the process of searching for a particular element that is present in the array one by one till the last element in the search element is found.
- The search uses a loop that iterates from the beginning till the last element to find the search element.
- The search continues for all the elements present in the array until the last element.
- The search of the target element is made after comparing it with each and every element that is present in the array.

AIM: Write a program to do Linear Search using a given Search Key in an un-
sorted Linear Array 'A' which has N values in it.
Description:
The linear search compares each element of the array with the search key until the
search key is found. To determine that a value is not in the array, the program must
compare the search key to every element in the array 'A'. It is also called "Sequential
Search" because it traverses the data sequentially to locate the element.
Algorithm: (Linear Search)
LINEAR
SEARCH (A, N, SKEY)
Here A is a Linear Array with N elements and SKEY is a given item
of information to search. This algorithm finds the location of SKEY in
A and if successful, it returns its location otherwise it returns -1 for
unsuccessful.
1.
Repeat step-2 for K = 0 to N-1
2. if(A [K] = SKEY) return K [Successful Search]
[End of loop of step-1 ]
3. return -1 [Un-Successful]
4. End.
In C++ language
Write a function that takes a 2 Demensional array and returns the position of the first row with an odd sum. Assume that the column size is fixed at 4. If no sum is odd, return -1.

First the program will read the row count (rowCount) and column count (columnCount) of the 2D array, both as int values. Then, the chars constituting the 2D array will be read on a row-by-row basis. After reading the 2D array, the program will check and correct each char within the 2D array according to the rules below. This process MUST be done by using a void function by sending the appropriate cell of the 2D array with a call-by-reference fashion. • If the row index is an even number, a char can only be a lowercase English value. • If the row index is an odd number, a char can only be ?, 7', or X'. • Any incorrect value MUST be changed into Finally, the checked and corrected 2D array will be printed out to the screen.
