Program body

#include iostream
#include string
#include fstream
using namespace std;

int main (){
fstream file;
file.open("sabi.txt",ios:: in |ios :: out | ios :: trunc);
if(file.is_open()){
cout<<"File opened successfully"<<endl;
}else {
cout<<"an error while opening file"<<endl;
}
file.close();
}

Working of program

this is what is shown when you have any file you specified before like here (sabi.txt)

I hope you enjoyed it

sorry The v shaped things around iostream etc can't be placed here as they are html componenets too
