**Explanation:** In C, division between two integers truncates any fractional part, so 12 divided by 5 results in 2.

```

return 0;
}
```

**Explanation:** The integer division of 5 by 2 results in 2, as any fractional part is truncated.

```
int main() {
int x = 5, y = 10, z = 5;
printf("%d\n", x == z);
return 0;
}
```

**Explanation:** The equality operator (==) checks if the values on both sides are equal. Here, x and z both have the value 5, so the expression evaluates to true, which is represented as 1.

**Explanation:** The expression !(5 == 3) evaluates to true because 5 is not equal to 3. The logical NOT operator (!) negates the result, so the final result is 1.

```
int main() {
int x = 5, y = 10;
printf("%d\n", x > y);
return 0;
}
```

**Explanation:** The greater than operator (>) checks if the left operand is greater than the right operand. Here, x is not greater than y, so the result is false, represented as 0.

**Explanation:** The greater than or equal to operator (>=) returns true (1) if the left operand is greater than or equal to the right operand. Here, 5 is equal to 5, so the result is 1.

```
int main() {
int x = 5, y = 10;
printf("%d\n", x != y);
return 0;
}
```

**Explanation:** The inequality operator (!=) returns true (1) if the operands are not equal. Here, x is not equal to y, so the result is 1.

**Explanation:** The logical AND operator (&&) returns true (1) if both operands are true. Here, both 5 and 3 are non-zero, so the result is 1.

```
int main() {
int x = 5, y = 0;
printf("%d\n", x && y);
return 0;
}
```

**Explanation:** In C, the logical AND operator (&&) returns false (0) if any of the operands are false. Here, y is 0, so the result is 0.

**Explanation:** The logical OR operator (||) returns true (1) if at least one of the operands is true. Here, both 5 and 3 are non-zero, so the result is 1.

```
int main() {
int x = 0, y = 0;
printf("%d\n", x || y);
return 0;
}
```

**Explanation:** In C, the logical OR operator (||) returns true (1) if at least one of the operands is true. Since both x and y are 0 (false), the result is 0.
