#include<iostream>
// for file operations
#include<fstream>
using namespace std;
int main(){
char file_name[30],ch = ' ';
cout<<"Enter file name to open:"<<endl;
cin>>file_name;
// now open file in output mode
fstream myfile;
myfile.open(file_name,ios::out);
// now read the line characterwise and write it to a file
cout<<"Enter the line to write to file"<<endl;
//reads character from console
cin.ignore();//ignore new line characters left in stream
while(1){
cin.get(ch);
if(ch == '\n'){
break;
}
myfile.put(ch);
}
myfile.close();
return 0;
}
Sample Run:
Enter file name to open: hello.txt Enter the line to write to file hello this is the line to be written to the file
