Source Code - Binary Code

Source code is what human programmers write.
Binary code is what the computer uses.

Human programmers (or hackers) write computer programmes using certain words and symbols in a very strict predefined way. There are many computer languages they can use.

Computers work with binary code, 1s and 0s (also called object code). A special computer programme (called a compiler or translater) is used to convert the source code into binary code.

If you have the source code, you can readily make the binary code. Also you can alter or enhance the source code, and change the programme how you want. If you only have the binary code, all you can do is run it. It is very difficult to reverse engineer binary into source code.

#include (iostream.h)

int main()
{
  cout << " Hello World!\n";
  return 0;
}
