capturing program input

For my program I used csis statements like

Code:

---


cout<< "Hello" << endl;
csis<< "Hello" << endl;

---

I put all the required statements in like csis.open("csis.dat") and csis.close
but I don't get why when I look at my csis.dat file it only shows what the program outputs and it doesn't capture the input that I put in when the program runs. How do I make it so that both the output and the input are captured? Thanks

If csis is just an ofstream that you opened, then it's only going to write what you tell it to write. Am I missing something? This seem like a silly question to assume data will be automatically written to a file that you haven't explicitly sent to be written.

I know that. My question is how do I capture the input that I put in when I run the program? How do I get the input into the csis.dat file?

Just write it. I don't know. Something like:

Code:

---

cin >> somevar;
csis << somevar;

---

Depends on how you're reading your data and how you want it formatted.

Maybe a bit off-topic, but does C++ allow this:

Code:

---

cin >> csis

---

Or do you have to use a variable like you did?

No, but if it was allowed, how would the data be parsed? What would be written to csis?

Another thing is that he probably wants to do something with the variable other than just write it to the file.

Surely, so it would be useless anyways, i was just a bit curios..
