Question

Write a C program that reads a file of integers. Finds the smallest, largest, sum, average (mean) and median. It also counts how many times each number is seen.

You are given a start program with code to sort an array of integers and print an array of integers.

Functions:

int main ( int argc, char * argv[] )

declare variables

fillArray(

getStats(

getModes(

sort(

writeStats

int fillArray( int array[1000] )

                receives an array of integers

                opens file in.txt

                reads the integers from the file storing each in the array

                closes the file

returns a count of how many ints in the array. If count is 1 then array[0] is only element with a valid integer

void getStats(int array[], int count, int &min, int &max, int &sum)

                receives array and count

                returns:

the smallest in min

largest in max

total in sum

void getModes( int array[], int count, int counts[100])

receives array count integers, initialize all elements to 0

loop thru the array and add one to the proper count counts[ array[i] ] ++;

returns the counts array with count of number 0 in counts[0], 1 in counts[1] etc.

void writeStats(int counts[100], int count, int min, int max, int sum, int median)

                opens file out.txt

Writes to file with labels:

count of how many integers read

min, max, sum, average and median

Label then the numbers 0-100 followed by count of how many times they occurred 5 per line

0 - 3, 1 – 2, 2 – 5, 3 – 0, 4 – 6, 5 – 22

6 – 0, and so on

close file

Given to start from this following code:

#include <stdio.h>
void swap(int a [], int p1, int p2) {
   int temp = a[p1]; a[p1] = a[p2]; a[p2] = temp;
}

void sort(int array[], int count) { //easy dumb bubble sort ascending order
   int c, d;
   for (c = 0; c < (count - 1); c++)
   {
       for (d = 0; d < count - c - 1; d++)
       {
           if (array[d] > array[d + 1]) /* For decreasing order use < */
           {
               swap(array, d, d + 1);
           }
       } // end d loop
   } // end c loop
} // end sort

void printArray(int array[], int count){
   int i=0;
   printf("enter printArray count %d ", count);
   while (i < count) {
       printf("%d%c", array[i++],
           ((i+1)%10 == 0)?' ':' ');
   }
  
}
int main(int argc, char * argv[]) {
   int count = 0;
   int array[20];

   for (count = 0; count < 20; count++) array[count] = 20 - count;
   printArray(array, count);
   sort(array, count);
   printArray(array, count);
   getchar();
   return 0;
}

Explanation / Answer

#include 02 #include 03 using namespace std; 04 05 int main() 06 { 07         ifstream inputFile; //file stream object 08         int choice; // menu choice 09         int number; // to hold a value from file 10         int total; //to hold a value from file 11         int large; // to hold largest value from file 12         int small; // to hold smallest value from file 13         int sum; // to hold sum of the values from file 14         int average; // to hold the average values from file 15         int quantity; // to hold the number of values entered 16 17         inputFile.open("TopicDin.txt"); // Open the file 18 19     do 20     { 21         //display the menu and get a choice 22         cout
