Answer 1) r15 contains address of the next instructions to be executed, because r15 is a program
Program Counter(PC). In processors, the PC is incremented after fetching an instruction and holds the memory address of the next instruction that would be executed.
Program Counter is holding memory address : 00001000 as per the results shown in screenshot of ARM simulator.
Answer 2) Content of the memory at the address : 00001000 is a Homework1.s file.
.S files is a source code file written in assembly.
Answer 3). Homework1.s file is a source code file. Source code is the source of a computer program. It contains declarations, instructions, functions, loops and other statements, which act as instructions for the program on how to function. Hence, It's an instruction.
