Create an integer array of size 50, name this array as "examArr". This array stores the grades of an exam. Initialize all elements in "examArr" with the value 0. Fill "examArr" with random integers in the range [0, 100]. Display the contents of "examArr", 5 elements per line. Display a summary report for "examArr" showing the following information: a. The maximum value in "examArr", and the location of the maximum number (the index/subscript of the maximum). If the maximum value is repeated, report the first location of the maximum value. b. The minimum value in “examArr", and the location of the minimum number. If the minimum value is repeated, report the first location of the minimum value. c. The average value of all numbers in "examArr". d. The average value of non-zero numbers in "examArr" (i.e. exclude all zeros in the array, if any). The frequency of each possible grade (i.e. how many students got the same grade). f. The mode of grades (i.e. the highest occurring grade (most frequent)). If there are more one grade, display all of them. e.

Create an integer array of size 50, name this array as “examArr". This array stores the
grades of an exam.
Initialize all elements in “examArr” with the value 0.
Fill "examArr" with random integers in the range [0, 100].
Display the contents of "examArr", 5 elements per line.
Display a summary report for "examArr" showing the following information:
a. The maximum value in “examArr", and the location of the maximum number (the
index/subscript of the maximum). If the maximum value is repeated, report the
first location of the maximum value.
b. The minimum value in "examArr", and the location of the minimum number. If
the minimum value is repeated, report the first location of the minimum value.
c. The average value of all numbers in "examArr".
d. The average value of non-zero numbers in “examArr" (i.e. exclude all zeros in the
array, if any).
e. The frequency of each possible grade (i.e. how many students got the same
grade).
f. The mode of grades (i.e. the highest occurring grade (most frequent)). If there are
more one grade, display all of them.
