Question

PLEASE HELP C++

Program #2 This problem is a modification of Problem 24 on page 302 of the Gaddis text with two small additions. (A scan of this problem can be found on the last page of the assignment.) In this assignment, your program will read in a list of random numbers from an input file, random. txt (found on eLearning in the "Homework Input Files" folder), and calculate the following statistics on those numbers A. B. C. D. E. F. The number of numbers in the file The sum of the numbers in the file The average of the numbers in the file The largest number in the file The smallest number in the file The second largest number in the file CS1336-Programming Fundamentals Page: 4 G. The second smallest number in the file Your program should then print out a report, similar to the following (note that these are demonstration numbers only; they are not accurate for the homework data file) Number of numbers Sum of numbers: Average of numbers: Largest number: Smallest number: Second largest number: Second smallest number: 235 5346 22.8 515 512 ogramming Notes: 1. Note that the number of numbers, the sum of the numbers, the largest and smallest numbers are integers, whereas the average should be a floating point data type printed to one decimal place 2. All of the numbers in the file are between 0 and 1000. Therefore, the minimum value can be found by using the following technique a. Create an int variable minValue and initialize it to some number larger than any number in the file, say 2000 Then include the following statement inside your file processing loop b. if (nextValue < minValue) minValue-nextValue;

#include <iostream>

#include <fstream>

#include <sstream>

#include <iomanip>

using namespace std;

int main()

{

ifstream in("random.txt"); //Opening file

string line; //Hold line by line string from file

int minValue = 2000, second_minValue = 2000, maxValue = -1, second_maxValue = -1;

int nextValue, totalNum = 0, sum_of_elems = 0;

if(in.is_open()) //To check file open or not

{

while(getline(in, line)) //read line by line from file

{

stringstream toNum(line); //to convert string to integer declaring stringstream

toNum >> nextValue; //converting string to int

sum_of_elems += nextValue; //sum of value one by one

if(nextValue < minValue) //to find smallest value

{

second_minValue = minValue; //hold second smallest value;

minValue = nextValue;

}

else

{

if(nextValue < second_minValue) //to find second smallest value

second_minValue = nextValue;

}

if(nextValue > maxValue) //to find largest value

{

second_maxValue = maxValue; //hold second largest value;

maxValue = nextValue;

}

else

{

if(nextValue > second_maxValue) //to find second largest value

second_maxValue = nextValue;

}

totalNum++; //total numbers count

}

//To handle if one value present in file

if(second_minValue > 1000)

second_minValue = minValue;

if(second_maxValue < 0)

second_maxValue = maxValue;

cout << "\n\t\tNumber of Numbers : " << totalNum <<endl;

cout << "\t\tSum of numbers : " << sum_of_elems << endl;

//Average converted to float and precision set to 1 decimal place

cout << fixed << setprecision(1) << "\t\tAverage of numbers : " << ((float)sum_of_elems / (float)totalNum) << endl;

cout << "\t\tLargest number : " << maxValue << endl;

cout << "\t\tSmallest numbers : " << minValue << endl;

cout << "\t\tSecond largest number : " << second_maxValue << endl;

cout << "\t\tSecond smallest number : " << second_minValue << endl;

}

else

{ //If unable to open file display error message

cout << "failed to open file" << endl;

}

return 0;
