#include <iostream>

#include <conio.h>
#include <fstream>
using namespace std;
int   main()
{
   ofstream fout;
 fout.open("KAT.TXT");
 for(int i=1;i<=100;i++)
  fout<<i<<endl;
 fout.close();
 return 0;
   
} 

simple program to write in text file 

#include <iostream>
#include <fstream>      // std::fstream
using namespace std;
int main () {

  fstream fs;
  fs.open ("test.txt");

  fs << " this line will store in test.txt  file and we can display it on console";

  fs.close();

  return 0;
}

#include <iostream>
#include <conio.h>
#include <fstream>
using namespace std;// read program from all what store in KA1T.TXT file
int   main()
{
   char ch;
   string line; 
   ifstream fin;
 fin.open("KA1T.TXT");
 
 while (fin) { 

          getline(fin, line); 
 
        cout << line << endl; 
}
  fin.close();

  return 0;
  
} 

Write a C++ program, which initializes a string variable to the content "Time is a great teacher but unfortunately it kills all its pupils. Berlioz" and outputs the string to the disk file OUT.TXT. you have to include all the header files if required.

 char str[300]="Time is a great teacher but unfortunately it kills
  all its pupils. Berlioz";
 fout<<str;
 fout.close();
 return 0;
}


Write a user-defined function in C++ to read the content from a text file OUT.TXT, count and display the number of alphabets present in it.





void alphabets()
{
 ifstream fin;
 fin.open("out.txt");
 char ch;
 int count=0;
 while(!fin.eof())
 {
  fin.get(ch);
  if(isalpha(ch))
   count++;
 }
 cout<<"Number of alphabets in file are "<<count;
 fin.close();
}


Write a function to count the number of blank present in a text file named "OUT.TXT"






void blankspace()
{
 ifstream fin;
 fin.open("out.txt");
 char ch;
 int count=0;
 while(!fin.eof())
 {
  fin.get(ch);
  if(ch==' ')
   count++;
 }
 cout<<"Number of blank spaces in file are "<<count;
 fin.close();
}
