get() function in c++ not working for files - c++

Question

I wrote the following code in codeblocks and since I am new to programming I would like to know the problem in simple words. Does the open() constructor create a new file if it does not exists?
#include<iostream>
#include<fstream>
#include<cstring>
using namespace std;
int main()
{
char str[80];
cout<<"Enter a string : ";cin>>str;
int len=strlen(str);
fstream file;
file.open("TEXT",ios::in|ios::out);
for(int i=0;i<len;i++)
file.put(str[i]);
file.seekg(0);
char ch;
cout<<"\nPrintitng Contents....\n";
int k=0;
while(file)
{
file.seekg(k);
file.get(ch);
cout<<ch;
k++;
}
return 0;
}

Answer 1

I think you don't have "TEXT". and fstream::open don't make file when if file that you want to read do not exist.
so you may try in different stream to read and write.
following code will help you.
#include<iostream>
#include<fstream>
#include<cstring>
using namespace std;
int main()
{
char str[80];
cout << "Enter a string : ";
cin >> str;
int len = strlen(str);
ofstream fout;
fout.open("TEXT.txt");
for (int i = 0; i<len; i++)
fout.put(str[i]);
fout.close();
ifstream fin;
fin.open("TEXT.txt");
char ch;
cout << "\nPrintitng Contents....\n";
while (!fin.eof())
{
fin.get(ch);
cout << ch;
ch = NULL;
}
fin.close();
return 0;
}
and you may improve your code like this
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main()
{
string str;
cout << "Enter a string : ";
cin >> str;
ofstream fout;
fout.open("TEXT.txt");
fout << str;
fout.close();
str.clear();
ifstream fin;
fin.open("TEXT.txt");
cout << "\nPrintitng Contents....\n";
fin >> str;
cout << str;
fin.close();
return 0;
}

Following code is more appropriate for C++, I think
#include<iostream>
#include<fstream>
#include<string>
using namespace std;
int main()
{
string str;
string newStr;
cout << "Enter a string : "; cin >> str;
int len = str.length();
fstream file;
file.open("TEXT", ios::out| ios::in );
if (!file.is_open())
return 0;
file << str;
file.seekg(0,file.beg);
char ch;
cout << "\nPrintitng Contents....\n";
file >> newStr;
cout << newStr;
file.close();
return 0;
}
