If i have a string with a word 'today' in it.

If a user inputs a char (lets say b).

how do I right the array to make it see if the char "b" is in the string today.

LOOP???
int i;
for(i=0; i<SIZE; i++)
{
guessedChar[i];
/*or*/
wordString[i];
}

To check if a character 'b' is in the string 'today', you can use a loop to iterate through each character in the string and compare it with the given character. Here's an example of how to do it:

```python
wordString = "today"
guessedChar = 'b'

for char in wordString:
if char == guessedChar:
print("The character '{}' is in the string 'today'.".format(guessedChar))
break
else:
print("The character '{}' is not in the string 'today'.".format(guessedChar))
```

In the above code, the loop iterates through each character in the `wordString`. If the current character is equal to the `guessedChar`, it means the character is present in the string. In that case, it prints a message and breaks out of the loop. If the loop completes without finding the desired character, it means the character is not in the string, and it prints another message.

Note: This code is written in Python. If you are using a different programming language, the syntax may vary slightly, but the logic remains the same.
