Question

Write a C++ program that reads a sequence of integer numbers from the input file data.txt. The sequence ends with a sentinel value of zero. The program should output the following into an output file results.txt: 

1. the count of all positive numbers.
2. the count of all negative numbers.
3. the sum of the positive numbers.
4. the sum of the negative numbers.
5. the maximum of negative numbers and
6. the minimum of positive numbers.

Use the following values in the file data.txt to test your program:

5

4

-8

-7

6

Answer 1

#include <fstream>
#include<iostream>
using namespace std;
int main() {
   int arr[30];
   ifstream file_in("data.txt");
   int count= 0;
   int x;
   while (count < arr[30] && file_in >> x)
   arr[count++] = x;
   ofstream file_out("results.txt");
   file_out<<"The integers are:"<<"\n";
   for (int i = 0; i < count; i++) {
      file_out << arr[i] <<' ';
   }
   int count_pos=0;
   int count_neg=0;
   int sum_pos=0;
   int sum_neg=0;
   for(int i=0;i<count;i++){
       if(arr[i]>0){
           sum_pos=sum_pos+arr[i];
           count_pos++;
       }
       else if(arr[i]<0){
           sum_neg=sum_neg+arr[i];
           count_neg++;
       }
   }
   file_out<<"\nThe number of positive numbers are: "<<count_pos;
   file_out<<"\nThe number of negative numbers are: "<<count_neg;
   file_out<<"\nThe sum of negative numbers are: "<<sum_pos;
   file_out<<"\nThe sum of negative numbers are: "<<sum_neg;
   file_out.close();
   file_in.close();
