Read and Implement code from a dat or text file

[ay2306]

Hey guys, I am making a program. For that now i am thinking of making a backup. Which is simple that i write all the data from code form in a .dat or .txt file.
Now I want my compiler to read code from that file and run it.
If any other file format can do it, just tell how to do it.

PS: I am not using visual c++, its just normal c++.
Thank you...

You would need to make a program that uses "ofstream" and "ifstream".

1: ofstream prints things to a file.
2: ifstream reads from a file.

Find out about both here : http://www.cplusplus.com/doc/tutorial/files/

No no. I know how to write, read and create a file.
See its like
suppose i have a file named "abc.format"
inside the file i have written
"#include<iostream.h>
void main()
{
cout<<"Hello";
getch();
}"

Now when i read the file, this code inside should be compiled.

Sounds like the OP is about make files and making make files (would you believe)

Maybe this reference helps as a starter:

Linux-type people love this stuff IIRC.

Which part didn't you get?

What is OP?
What is IIRC?
What is the answer/solution, how do i do it?

For your three questions, in order:

1) Most people believe the widely used acronym

OP

stands for "original poster." But no, those people are wrong and stupid. It obviously means "overpowered."

2) "If I remember correctly."

3) What you are referring to, and what @kemort has linked you, is makefile, which I believe is basically using a compiler's executable to run code through a file that has syntactically correct code inside it. I might be wrong on this, due to not having had much exposure to this stuff.

Thanks YFGHNG for the explanation, I've been tied up with other things.

@ay2306
Unfortunately I can't add anything to what I guessed might be relevant. I'd help if I could but I've plumbed the depths of my knowledge on what may be a red herring anyway. Good luck with your quest.
