Object code is machine-dependent code that has been compiled from high-level source code. Every translation unit in the source code is compiled separately and independently. External dependencies are represented as symbol tables. Once compiled, the object code can be linked to produce an executable. The linker is the only process that "sees" the whole code and makes use of symbol tables to determine the common dependencies and thus eliminate redundant code from the final executable. The linker's optimiser can also inline expand function calls to improve overall efficiency.
to get your PAC code (porting authorisation code) you need to visit www.paccodes.co.UK and enter your current and new mobile phone provider and you can get your PAC code. hope this helps.
Yes
compiler
Coverts source code into object code
It coverts your source code into machine code so the computer can execute it.
No, they are two different things, source code is human-readable and machine code is machine-readable (though it can be represented in assembly)
A program that translates source program into object code.
Translates from source code to object module. What else did you think?
Programmers used (and still use) translators to convert the source code into object code.
Source code is code written in a programming language, such as C++ or Java. It is designed to be architecture-independent and human-readable. Source code must be converted to object code (aka machine code) before it can be executed. Object code is architecture-dependent and is not easily human-readable (think ones and zeros). The point of this setup is that you can ensure that code you write in a programming language (source code) can be executed on ANY architecture that has a proper compiler.
False. A compiler converts source code into object code.
You cannot. Object code files are machine code files that have yet to be linked. There is no way to convert object code back to its original source code.
