String Program Options Complete any Two of the following. String Program Options Find last name Input first and last name into one String Output only the last name. Push: Support middle names Write a mad-lib program Have the user enter at least 4 pieces of information. Noun, Adverb (honestly), Adjective (messy), Verb, Geographical location, … The computer will generate the mad-lib English to Pig-Latin translation program. The rules of Pig Latin are If the word begins with a consonant -- such as ``string,'' ``Latin'' -- divide the word at the first vowel, swapping the front and back halves and append ``ay'' to the word -- ``ingstray,'' ``atinLay.'' If the word begins with a vowel -- such as ``am,'' ``are,'' ``i'' -- append ``yay'' to the word -- ``amyay,'' ``areyay,'' ``iyay.'' If the word has no vowels (other than 'y') -- such as ``my,'' ``thy'' -- append ``yay'' to it -- ``myyay,'' ``thyyay.'' Level 1, Translate a single word Level 2: Translate a sentence. Input a word, output whether or not it is a palindrome.
