Write a function void camelcase(char* word) where the argument "word" to the function consists of at least two groups of lowercase alphabetic characters, not necessarily forming actual words in the dictionary, separated by underscores, such as “ran_dom_word” or "this_is_my_first_programming_assig nment". the function should remove underscores from the string and rewrite it in lower camel case (several words joined together where the first letter of the entire string is lowercase, but subsequent first letters are uppercase). watch out for the end of the string, which is denoted by ‘\0’. it’s possible that a user-provided input string may contain uppercase alphabetic characters, numeric characters, special symbols, whitespace etc. as well. you should accept such an input string too. for convenience, convert the string into a valid form before you use it for the function below are some conversion examples of what you should implement:
