Because vi is a character and you have initialised as a string.

Single quotes represent character
Double quotes represent String

Answer 2

try
char vi='D';

Answer 6

Vinay Jaiswal thats because its 2 different types. Python and js ignore that. Nvm if u use " " or ' '. But C family and Java (as i know C is parent for Java?🤔🤔) are strict for this. So, " " not equals to ' '. Double quotes " " - are for strings, single quotes ' ' - are for chars
