It's about making your code clear and understandable, not just for machines but for fellow programmers as well. Improving readability can make maintenance and collaboration more efficient, enhancing the overall quality of your work. Simply using inline assembly to do an operation that can easily be expressed in C++ - like adding two values or searching in a string - is actively counterproductive, because: the compiler knows how to do this equally well. to verify this, look at its assembly output (e.g. gcc -S) or disassemble the machine code. Assembly is a general name used for many human-readable forms of machine code. It naturally differs a lot between different CPUs (Central Processing Unit), but also on single CPU there may exist several incompatible dialects of Assembly, each compiled by different assembler, into the identical machine code defined by the CPU creator.
