What is the error in the code?" Char ch; Int vowels=0,others=0; Cin>> ch; While((ch>= ‘A’ && ch <+ ‘Z’) || (ch>=’a’ && ch <= ‘z’)){ Switch(ch) { Case’a’: Case’A’: Case’e’: Case’E’: Case’i’: Case’i’: Case’o’: Case’O’: Case’u’: Case’U’: ++vowels; Break; Default: ++others; }} Cout<< vowels<< ‘\n’<< others;

• A. The while loop is an endless loop. Whatever value of ch has in the beginning, will remain the same, as ch is not updated within the loop.
• B. There is no need to declare a and A and hence all other vowels gain in switch as it is case insensitive.
• C. The switch statement’s two case constants are identical case i and i which is an error
• D. More than one is correct from above.
