Hi guys. I have to write a program in C to convert Arabic Numbers to Roman Numerals. This program compiles, but when i type in any number the result i get is MMDDCCLLXXVVI followed by a string of random characters. Does anyone have any idea why this could be?<\/p>\n

ps. don’t worry about the BatchConvert function, one step at a time atm! \ud83d\ude1b<\/p>\n

Thanks in advance.<\/p>\n<\/td>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","template":"","meta":{"inline_featured_image":false,"iawp_total_views":7},"question-category":[],"question_tags":[],"class_list":["post-548","question","type-question","status-publish","hentry"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question\/548","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question"}],"about":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/types\/question"}],"author":[{"embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/comments?post=548"}],"wp:attachment":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/media?parent=548"}],"wp:term":[{"taxonomy":"question-category","embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question-category?post=548"},{"taxonomy":"question_tags","embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question_tags?post=548"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
