Algorithm

1. Input: Receive a C-style string (character array) as input.

2. Initialization: Initialize a variable length to 0 to store the length of the string.

3. Loop: Use a loop to iterate through the characters of the string.
    While the current character is not the null character ('\0'):
     Increment the length variable.
       Move to the next character in the string.

4. Output: Return the final value of the length variable as the length of the string.
