Write and Test a Function to Convert Alphabetic Characters to Uppercase
How can you write and test a function to convert alphabetic characters to uppercase?
What steps should be followed to create the function named toUpper as described in the data provided?
Steps to Create toUpper Function:
1. Define the toUpper function with a single parameter for the input string.
2. Initialize an empty string variable to store the converted string.
3. Iterate through each character in the input string.
4. Check if the character is alphabetic using isalpha() function, if yes then proceed, if not append the character unchanged.
5. Convert the alphabetic character to uppercase using upper() function and append it to the result string.
6. Return the final result string after iteration is complete.
7. Test the toUpper function with different inputs to ensure correctness.
Explanation:
The given data provides a clear explanation of how to create and test a function named toUpper in order to convert alphabetic characters to uppercase while keeping non-alphabetic characters and uppercase characters unchanged.
The step-by-step process includes defining the function, initializing a variable to store the converted string, iterating through each character, checking for alphabetic characters, converting them to uppercase, and finally testing the function with different inputs to ensure its accuracy.
By following these steps and implementing the provided Python example, you can create a reliable function that effectively converts alphabetic characters to uppercase without altering other characters in the input string.
