The program reads data from one of the files given here. The first line of each file can contain any string (may
have multiple spaces) that should be read but not used. Following the string are numbers whose values are
equalled to or greater than 1.
There should be no assumption of how many numbers are in the file. There should be no assumption of the
largest number in the file.
While reading each number from the input file, the program should keep track of (tally) the number of occurrences
(frequency counts) of each number whose value is 1 up to certain value inputMax (entered by user) and program
stores the frequency counts in an array of size inputMax. The program reads all numbers in a file but it does not
tally the occurrence of numbers that are larger than inputMax. The frequency (occurrence count) of a number is
the count of how many times the number occurs. For example, if use input inputMax is 20, the program keeps
track of the occurrence counts for the number 1, 2, 3, 4,.20, and it ignores the numbers that are larger than 20.
The program should NOT store the numbers it reads from the file because there is no need to do it and there are
too many numbers (millions of numbers). All it needs to store are the occurrence counts of numbers from 1 to
inputMax. For example, if user input inputMax is 20, then the occurrence count array size is 20.
int readNumbersAndTallyOccurrences(occurrences, size, infile);
Parameters:
occurrences: array of integers
size: array size
infile: input file (ifstream object), passed by reference.
The input file is opened in main function, then passed to this function.
Function to read all the numbers in the input file using a loop
It keeps track of the occurrence of each number if it is < or equal to size in the array parameter
Code reads but do no process numbers that are greater than the size. For example, if user enters 20 as
the maxInput, the code reads but does not use numbers that are > 20.
Function does not print anything (main function and printCounts function does the printing)
Function returns the count of all numbers in the file.
void printCounts(occurrences, size);
Parameters:
occurrences: array of integers
size: array size
Print the values of the occurrence counts in the array using a loop
void findMostAndLeastOccurrence(occurrences, size, highestCountindex, lowestCountindex);
Parameters:
occurrences: array of integers
size: array size
highestCountindex: subscript of array element with the highest occurrence count, passed by reference
lowestCountindex: subscript of array element with the lowest occurrence count, passed by reference
This function find the number with the most and the number with the least occurrence in the array
It does not print anything (no "cout" in here, main function and printCounts function does the printing)

For numbers1.txt input file with maxlnput 15
This program reads a number file and display the number occurrence statistics.
Enter an existing file name: numbers1.txt
Enter the highest number to get occurrence count (must be > 0): 15
