Simple ARM hello world program

Job ID: 34743283

Budget: $10 – $30 AUD

Hi,
I need a simple ARM (arm64) hello world program in assembly.

Basically it's an assembly file (with .s extension) that would read a string from standard input and prints out the length of string. Just need it to learn how to code in assembly.

You can't use C/C++ functions (except for printf and scanf) and can't use automated tools such as a GCC compiler to turn C into assembly.
