> 2. The following program fragments illustrate the logical operators. Show the output produced by each, assuming that `i`, `j`, and `k` are `int` variables.

a. `i = 10; j = 5;`
```c
printf("%d", !i < j);

// Expected output: `1`, because `!i` evaluates to 0, and 0 is less than 5, so that expression evaluates to true, or 1.
```

b. `i = 2; j = 1;`
```c
printf("%d", !!i + !j);

// Expected output: `1`, because !!2 evaluates to 1, and !j evaluates to 0
```

c. `i = 5; j = 0; k = -5;`
```c
printf("%d", i && j || k);

// Expected output: `1`, because i && j should evaluate to 0, but `0 || 1` should evalulate to true.
```

d. `i = 1; j = 2; k = 3;`
```c
printf("%d", i < j || k);

```
