Я пытаюсь просканировать мою строку ниже на наличие гласных и увеличить их количество. Тем не менее, это дает мне перерыв и необработанные ошибки исключения. Кажется, он возвращает только номер первого гласного (а) в строке. Общее количество гласных должно быть 491.

char Decl[] = "We hold these truths to be self-evident, that "
"all men are created equal, that they are "
"endowed by their Creator with certain "
"unalienable Rights, that among these are "
"Life, Liberty and the pursuit of Happiness. "
"That to secure these rights, Governments are "
"instituted among Men, deriving their just "
"powers from the consent of the governed, "
"That whenever any Form of Government becomes "
"destructive of these ends, it is the Right of "
"the People to alter or to abolish it, and to "
"institute new Government, laying its foundation "
"on such principles and organizing its powers in "
"such form, as to them shall seem most likely to "
"effect their Safety and Happiness. Prudence, "
"indeed, will dictate that Governments long "
"established should not be changed for light and "
"transient causes; and accordingly all epxerience "
"hath shewn, that mankind are more disposed to "
"suffer, while evils are sufferable, than to "
"right themselves by abolishing the forms to "
"which they are accustomed. But when a long train "
"of abuses and usurpations, pursuing invariably "
"the same Object evinces a design to reduce them "
"under absolute Despotism, it is their right, "
"it is their duty, to throw off such Government "
"and to provide new Guards for their future "
"security. Such has been the patient sufferance "
"of these Colonies; and such is now the "
"necessity which constrains them to alter their "
"former Systems of Government. The history of "
"the present King of Great Britain is a history "
"of repeated injuries and usurpations, all "
"having in direct object the establishment of "
"an absolute Tyranny over these States. To "
"prove this, let Facts be submitted to a "
"candid world. Entered by Thomas Berny ";
