Suppose you have a main() with three local arrays, all the same size and type (say

float). The first two are already initialized to values. Write a function called

addarrays() that accepts the addresses of the three arrays as arguments; adds the contents

of the first two arrays together, element by element; and places the results in the

third array before returning. A fourth argument to this function can carry the size of the

arrays. Use pointer notation throughout; the only place you need brackets is in defining

the arrays.

Given a square matrix of size N*N, print the sum of upper and lower triangular elements. Upper Triangle consists of elements on the diagonal and above it. The lower triangle consists of elements on the diagonal and below it.

8.3) write a program for the development board that repeatedly counts:

• from 0 to 9 in 1-second increments

Given an array arr[] sorted in ascending order of size N and an integer K. Check if K is present in the array or not. (Use Binary Search)

Input: N = 5

K = 6

arr[] = {1,2,3,4,6}

Output: 1

Explanation: Since, 6 is present in the array at index 4 (0-based indexing),

output is 1

Create a C program that will be able to compute the prelim grade up to finals grade of a certain student.

Note: (Only the prelim grade, midterm grade and final grade will be entered.)

Specification:

Total Grade= (Prelim Grade *.30)+(Midterm Grade*.30) + (Final Grade*.40)

Equivalent:

98-100 1.00 83-85 2.25

95-97 1.25 80-82 2.50

92-94 1.50 77-79 2.75

89-91 1.75 75-76 3.00

86-88 2.00

74 and below 5.00

Remarks: (note: separate the condition of remarks to equivalent)

Pass>=75 Failed<=74

Write a program that reads the numbers and sorts them by using the Counting Sort algorithm and finally search a number from that array using Linear Search Algorithm.

Input: 3 6 5 4 7 8 9

 Search Item: 7

Output: Sorted Array: 3 4 5 6 7 8 9

 Search item 7 is found.
