Question
![The image provides instructions for generating C declarations for various variables and assignments, with emphasis on identifying equivalent C statements that accomplish similar tasks. It suggests specifying whether the declaration should be signed or unsigned, if applicable.
Each part presents assembly-like instructions, labeled by letter:
(a)
- LDRH R0, red
- ADR R1, blue
- LDR R2, purple
- STRH [R0, R1, R2, LSL #1]
(b)
- LDR R0, green
- ADD R0, R0, #1
- LDR R1, =0
- STRD R0, R1, violet
(c)
- LDRB R0, black
- LDR R1, =5
- UDIV R2, R0, R1
- MLS R0, R1, R2, R0
- STRB R0, white
(d)
- LDRD R0, R1, orange
- LSL R1, R1, #1
- ORR R1, R0, R1
- LSL R0, R0, #1
- LSL R0, R0, LSR #31
- STRD R0, R1, yellow
These instructions resemble a mix of ARM assembly commands dealing with load, arithmetic, and store operations. The task likely requires translating these logical operations into equivalent C code, considering data types and addressing methods appropriate for such hardware-level instructions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd2291e09-7fcf-4fac-bc31-e34a7ce4842f%2F636f5eb1-fa7c-4d9a-a990-ec6efb88c5cc%2F3oi5ta_processed.jpeg&w=3840&q=75)
