C program to convert a text into its equivalent hexadecimal value to be used in Loadrunner

Loadrunner has a built in function called web_convert_param function which converts HTML to a URL or plain text or the vice-versa.
But in my case, I had a file upload script in which the text files names that are uploaded are converted into its equivalent hexadecimal value and they were passed in the request url.
Since they were passed in the url the hexadecimal values were also appended with %.

For example

Text File uploaded : text vinoth.txt

hexadecimal value passed in the url: 74%65%78%74%20%76%69%6E%6F%74%68%2E%74%78%74%

Below is the C program which does the above conversion (Plain Text to Hex conversion)

Output:
