It’s MIPS assembly language.

What’s the binary and the hexadecimal representation of machine code of the following MIPS instruction?

Add $t0,$t0,$zero

I have absolutely no idea.

Hi,

You can use an assembler and a hex editor to easily find out. For instance, you can use GAS (the GNU assembler – what GCC uses as its backend) to assemble this (you might need to build cross-binutils for MIPS in order to do this).

Please colud you explane to me that is the difference between source code and machine code.

Thank you

Source code is text written in a computer programming language. source code is written by programmers.
Machine code is a system of instructions and data executed directly by a computer’s central processing unit. Usually compilers and interpreters convert the source code into machine code. machines can only understand 0 and 1.
