# Out of Bounds

## Out of Bounds

**Example 1: C**

**Vulnerable Code:**

```c
cCopy codeint arr[10];
for (int i = 0; i <= 10; i++) {
    arr[i] = i;
}
```

**Reason for vulnerability:** Array index goes out of bounds, leading to undefined behavior.

**Fixed Code:**

```c
cCopy codeint arr[10];
for (int i = 0; i < 10; i++) {
    arr[i] = i;
}
```

**Reason for fix:** Ensure the array index is within bounds.

**Example 2: Python**

**Vulnerable Code:**

```python
pythonCopy codearr = [0] * 10
for i in range(11):
    arr[i] = i
```

**Reason for vulnerability:** Array index goes out of bounds, leading to an IndexError.

**Fixed Code:**

```python
pythonCopy codearr = [0] * 10
for i in range(10):
    arr[i] = i
```

**Reason for fix:** Ensure the array index is within bounds.
