This program is to determine a lowercase or an uppercase vowel from the user's given input. We used "using namespace std;" because in the Visual studio, the header file "iostream" cannot be used without it. We used 'if else if' statement to determine uppercase and lowercase vowels.
Beginner's should know that '||' used in the 'if else if' statement means 'or'. It means that if not this, then this.
