Week 13a solution

13 a) Write a C++ program that creates a file of data in the form 
of the temperature.Fill the file with at least 50 temperature readings. 
Call this program store_temps.cpp and the file it creates raw_temps.txt.

Program:
#include<iostream>
#include<fstream>
using namespace std;
int main()
{
 double temp;
 ofstream out("raw_temps.txt");
 for(int i=1;i<=50;i++)
 {
  if(i<=25)
   temp=20+.1*i;
  else
   temp=20+.25*i;
  out<<temp<<"\n";
 }
 out.close();
 cout<<"Temparature readings in the file are \n";
 ifstream in("raw_temps.txt");
 cout<<in.rdbuf();
 in.close();
 return 0;
}

Output:

Temparature readings in the file are
