include (Text) files from directory (1 by 1) automatically and print what in it.

#include<iostream>
#include<conio.h>
#include<fstream>
#include<windows.h>
using namespace std;
int main()
{
string ptr,a;
string b="E:\\project\\";

WIN32_FIND_DATA file;
HANDLE obj = FindFirstFile("E:\\project\\*",&file);
if(obj)
{
// do
// {

ptr=file.cFileName;
a=b+ptr;
ifstream fin;
fin.open("a.txt");
char ch;

while(!fin.eof())
{
fin.get(ch);
cout<<ch;

}
fin.close();
cout<<ptr<<endl;

}
while(FindNextFile(obj,&file));

cout<<endl;

getch();
return 0;
}

ifstream fin;
 fin.open("a.txt");
 char ch;
 
 while(!fin.eof())
 {
 fin.get(ch);
etc...

You are intending to open a.txt as an input file?

"a.txt" is a literal. The a in the literal is not your string a.

You might try:

fin.open(a.c_str());

i want to give just name of directory and the program will open the text file automatically?? how it is possible

You have to have a complete path to the file to open it.

If you supply only the directory to the file, then your program must iterate the directory and create a path consisting of the supplied path to the directory + the name of the file then open the file using this complete path.
