Difference between .equ and .word in ARM Assembly?

Question

I am curious - What is the difference between `.equ` and `.word` directives in ARM assembly, when defining constants?

Accepted Answer

`.equ` is like `#define` in C:

```
#define bob 10
.equ bob, 10
```

`.word` is like `unsigned int` in C:

```
unsigned int ted;
ted: 
.word 0
```

Or initialized with a value:

```
unsigned int alice = 42;
alice:
.word 42
```
