Question: Why Is Object Code Necessary?

What is object code and executable code?

The main difference between object code and executable code is that object code is a program or a file that is created after compiling the source code while executable code is a file or a program that indicates tasks according to encoded instructions the CPU can directly execute..

What is the difference between object file and executable file?

The main difference between object file and executable file is that an object file is a file that is generated after compiling the source code while an executable file is a file that is generated after linking a set of object files together using a linker.

Which record contains the object code?

Object code is written to an output device, forming executable object program. SIC object format contains three record types: Header, Text, and End records. Header record contains program name, starting address, and length of program. Text records contain the machine code instructions, program data, addresses.

What is meant by object code?

In a general sense object code is a sequence of statements or instructions in a computer language, usually a machine code language (i.e., binary) or an intermediate language such as register transfer language (RTL).

What is object code with example?

Object-code definitions Object code is the language that a central processing unit can understand after it has been translated by the compiler from the programming source code. An example of object code is ELF (Executable and Linking Format). … The machine language representation of programming source code.

Is object code same as machine code?

Machine code is binary (1’s and 0’s) code that can be executed directly by the CPU. … Object code is a portion of machine code that hasn’t yet been linked into a complete program. It’s the machine code for one particular library or module that will make up the completed product.

What is the difference between source code and executable code?

Originally Answered: What is the difference between source code, object code, and executable code? Source code is what humans can read, write and understand. Object code is what some computer programs produce from Source code. Executable code is what computers can execute.

What is difference between object code and source code?

Source code is generally understood to mean programming statements that are created by a programmer with a text editor or a visual programming tool and then saved in a file. Object code generally refers to the output, a compiled file, which is produced when the Source Code is compiled with a C compiler.

What is Object Program How is it generated?

Object code is produced when an interpreter or a compiler translates source code into recognizable and executable machine code. Object code is a set of instruction codes that is understood by a computer at the lowest hardware level.
