Run the flag for a demo of finding a letter in a word function. The demo program does not provide input validation (check for a blank entry, more than one letter, or entering a non-letter). Validation is left as an exercise for the coder. I also include a line of code that will convert the found letter to uppercase in one line of code. Yes, 3 lines of code to find the letter and 1 to convert it... Very easy... You could convert the case of a whole word by looping through the function the length of the word and saving the output.
