1. Write a program that will sort some given value in ascending and descending order. 2. Write a program that will calculate the average of the data that has been given by the user. Use array to do this. 3. Write a program that will take the scores of m numbers of quizzes of n numbers students; prints the quizzes numbers corresponding to each student and gives the average marks of best (m-1) number of quizzes for each student. 4. Write and test the following function that returns the minimum value among the first n float min( float a[], int n) elements: 5. Write and test the following function that returns the index of the first minimum value among the first n elements: float minindex( float a[], int n) 6. Write and test the following function that returns both the minimum and maximum values among the first n elements: float extreme( float& min, float& max, float a[], int n)

7. Write and test the following function that returns both the largest and second largest (possibly equal) values among the first n elements: float max( float& max_1, float& max_2, float a[], int n)

8. Write and test the following function that returns the Standard Deviation of a data set of n numbers a0, a1, a2, a3, … , a(n-1). double stdev( double a[], int n) n −1

Standard Deviation is defined by the equation, S =

∑ (a i =0

_

i

− a)

n −1

__

; where

a

is the mean

value of the data. 8. Write a program that will create Pascal’s Triangle in the square matrix. 1 0 0 0 0 1 1 0 0 0 1 2 1 0 0 1 3 3 1 0 1 4 6 4 1 9. Write a program that will multiply two matrix of any columns and row if it passes the test for the conditions of matrix multiplication.
