Question

PSEUDOCODE and PYTHON source code!

Program 4: Design (pseudocode) and implement (source code) a program (name it MinMaxAvg) to determine the highest grade, lowest grade, and the average of all grades in a 4-by-4 two-dimensional arrays of integer grades (representing 4 students’ grades on 4 tests). The program main method populates the array (name it Grades) with random grades between 0 and 100 and then displays the grades as shown below. The main method then calls method minMaxAvg()that takes a two-dimensional array of type integer as a parameter and prints out the class highest grade, the class lowest grade, and class average grade as shown below. Document your code and properly label the outputs as shown below.

Sample run 1:

Array Grades:
    38   44   22   91  
    81   60   71   80
    99   49   98   63
    71   33   93   49

Highest grade:   99
Lowest grade:    22
Class average:   65.13

Sample run 2:

Array Grades:
    60   88   98   100
    87   75   68   93
    95   86   98   73
    56   73   88   71

Highest grade:   100
Lowest grade:    56
Class average:   81.82

Answer 1

Code:

Sample Output:

$python main.py
Array Grades
82   92   36   59   
24   67   47   63   
45   82   28   82   
3   71   78   62   
Highest Grade:  92
Lowest Grade:  3
Class average:  57
