output within compiler and from exe file differs - c++

Question

i am using turbo c++. when i run the following code from compiler i get different answer at marked point in function result(int) then what i get from running .exe file created.
#include<fstream.h>
#include<conio.h>
#include<process.h>

pls note that program is yet not fully complete so some features dont work.
i don't know how to include dat file data nor screenshot here.
i don't use visual c++ cause my pc is slow.
i don't use codeblocks cause i dont know how to use it. above code give hundreds of error even after adding "using namespace std;"
pls help me solve it. if you need anything else then ask me. thanks

Answer 1

I get different answer (…) in function result(int) then what I get from running .exe file created.
When you execute your program from the IDE a different working directory is used so different files are seemingly present/missing. Usually the working directory is configurable.
By the way, the goto is not needed. Really, it is not.
