Exercise 1 (3Points)

Write a program that finds the two largest and two smallest integers in a file that’s filled with numerical values. The input should be read from a file numbers.dat, and the output should be displayed to the screen as well as written to a file named stats.dat. (Hint: before you start, read all you can about EOF-controlled loops in your textbooks)

The format of the input is as follows:

n1 n2 n3 n4 …

The format of the output is as follow:

The file contains ??? numbers
The two largest values in the list are: … …
The two smallest values in the list are: … …


Exercise 2 (3 Points):

A sequence of numbers is monotonic increasing if the values are in sorted order, that is, they are arranged in an increasing order. For example, 1, 1, 3, 4, 9 is a monotonic sequence, but 1, 3, 2, 4, 9 is not a monotonic sequence because 3 is greater than 2.
Write a program that determines whether an input sequence is in monotonic increasing order.

#include <iostream>
#include <fstream>
using namespace std;

int main ()
{

int num;
int max=0;
int min=0;


ifstream infile;
ofstream outfile;

infile.open("numbers.dat"); //open the input file
outfile.open("stats.dat"); //open the output file

cout<<"Enter a number";
infile>>num;


while (!infile.eof())

{
if(num>max)
max=num;
else(num<min);
min=num;

infile>>num;
}

cout<<"largest number:";
cout<<max<<endl;

cout<<"smallest number:";
cout<<min<<endl;

// close files
infile.close();
outfile.close();

return 0;
}
