![### Code Error Analysis
#### Code Snippet:
```cpp
void myfun(char* p)
{
*p = toupper(*p);
}
int main()
{
string myword = "YouHadMeAtHello";
for (int i = 0; i < 10; i++)
{
myfun(myword[i]);
}
cout << myword << endl;
return 0;
}
```
#### Problem Statement:
What is wrong with the following code snippet?
#### Options:
- ○ Must use `c_str()` to access individual characters of the string variable `myword`
- ○ Array indices are out of bounds
- ○ Must use `atoi()` to convert integers to characters
- ○ The `toupper()` function cannot be applied to a single character
#### Analysis:
- The code attempts to convert the first 10 characters of the string `myword` to uppercase using the `myfun` function.
- The function `myfun` is intended to take a pointer to a character and convert it to uppercase using `toupper`.
- In the `main` function, `myfun` is called with `myword[i]`, which is a character, not a pointer.
- Passing `myword[i]` by reference would resolve this issue.
#### Correct Explanation:
The array indices are not out of bounds, as the code accesses the first 10 characters. The correct option should indicate that `myfun(myword[i])` does not pass a pointer.
#### Suggestion for Correction:
Change the function call to pass the address of the character:
```cpp
myfun(&myword[i]);
```
This ensures the character element is treated as a pointer when passed to `myfun`.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F453e88de-567d-41f5-a415-910b75fd7930%2F3f61187c-64da-45a0-aed7-c542fc524165%2Focb3dzr_processed.jpeg&w=3840&q=75)
