Linux: Compile both files and push the content of the first to the second binary with a pipe in terminal else use a socket.. you can try to ouput the data with a binary-stream and the second binary can use the same techniqe to pushs it into a array.. i hope that helps you..

Since they're separate programs, that means they each have a main() function. Because of that you can't link them together. What you can do, however, is use the shell to redirect the output from one program to the input of another. For example:

program1 | program2

The above creates a so-called "pipe". What it does is feed program2 with the output of program1. Only the standard input and standard output are redirected that way. In C++ that means std::cin and std::cout. Anything printed on std::cerr or std::clog is not redirected, so make sure to never print errors, warnings or other status/informational messages on std::cout. Only print the payload data and use std::cerr or std::clog for anything else.
