charecter and string hope it helps have a

Answer 2

'a'   is a character.

"a"  is a String.

Anything written in single inverted commas is accepted as a character. & mentioned in double inverted commas is accepted as a String.

This is the major difference between  'a'  & "a" in C++.

• 'a' is a character literal. It's of type char, with the value 97 on most systems (the ASCII/Latin-1/Unicode encoding for the letter a).

• "a" is a string literal. It is of the type const char[2], and refers to an array of 2 chars with values 'a' and '\0'. In most, but not all, contexts, a reference to "a" will be implicitly converted to a pointer to the first character of the string.

Both

cout << 'a';    

cout << "a";

• Happen to produce same output, but for the different reasons. The first prints a single character value.
• The second successively prints all characters of a string (except for the terminating '\0') -- which happens to be a single character 'a'.

• String of the literals can be arbitrarily long, such as "abcdefg". Character literals almost always contain just the single character.

Hence,  The difference is:   'a' is a character  &  "a" is a String.
