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.
