File data71.txt numbers:

23
56
78
90
34
123
456
789
986

Please find the code below:

#include <iostream>
#include <string>
#include <fstream>
#include <sstream>

using namespace std;
int main( )
{

   ifstream infile;
   infile.open ("data71.txt"); //name of file here. plz mention Complete path if file is not at root

   int min = 9999;
   int max = 0;
   int temp;
   int evenCount =0;
   int totalNumberCount = 0;
   if (infile.is_open()) //if file opened
   {
       while(infile>>temp ) { //get row from text file
           if(min>temp){
               min=temp;
           }
           if(max<temp){
               max=temp;
           }
           if(temp%2==0){
               evenCount++;
           }
           totalNumberCount++;
       }
       infile.close(); //close file
       cout<<"File scan done........"<<endl;
   }
   else //if file not found show the below message
   {
       cout << "Sorry, we could not find the file." << endl;
   }

   cout<<"Total number count : "<<totalNumberCount<<endl;
   cout<<"Total even number count : "<<evenCount<<endl;
   cout<<"Minimum number is : "<<min<<endl;
   cout<<"Maximum number is : "<<max<<endl;

   return 0;
}
