        \nThe assignment operator \u2018=\u2019 is used for assigning a variable to a value. This operator takes the expression on its right-hand-side and places it into the variable on its left-hand-side.
        \nFor example: m = 5;<\/p>\n

        Question 19.
        \nWhat do you mean by the precedence of operators? Give an example.

        \nWhat is implicit conversion? Give an example.
        \nAnswer:
        \nWhen two operands of different types are encountered in the same expression, the lower type variable is converted to the higher type variable which is called implicit conversion.
        \nFor example, float = int + float<\/p>\n

        Question 21.
        \nExplain the use of explicit conversion with an example.
        \nAnswer:

        \nAnswer:<\/p>\n

          \n
        • C++ is a typed, compiled, general-purpose, case-sensitive, free-form programming language that supports procedural, object-oriented, and generic programming.<\/li>\n
        • C++ is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features.<\/li>\n
        • C++ was developed by Bjarne Stroustrup starting in 1979 at Bell Labs in Murray Hill, New Jersey as an enhancement to the C language and was originally named C with Classes but later it was renamed C++ in 1983. by Rick Masatti.<\/li>\n
        • C++ is a superset of C, and virtually, any legal C program is a legal C++ program.<\/li>\n<\/ul>\n

          Question 2.
          \nWrite the applications of C++.
          \nAnswer:<\/p>\n

            \n
          • It is a versatile language for handling very large programs<\/li>\n
          • It is suitable for virtually any programming task, including development of editors, compilers, databases, communication systems and any complex real life application systems<\/li>\n
          • It allows us to create hierarchy-related objects, so we can build special object-oriented libraries which can be used later by other programmers.<\/li>\n
          • While C++ is able to map the real-world problem properly, the C part of C++ gives the language the ability to get close to the machine-level details.<\/li>\n
          • C++ programs are easily maintainable and expandable.<\/li>\n<\/ul>\n

            Question 3.
            \nWrite a short note on the keywords of C++.

            \n\"1st<\/p>\n

            Question 4.
            \nWrite the rules to be followed, while naming the identifier.
            \nAnswer:
            \nThe identifier is a sequence of characters taken from the C++ character set. The rules for the formation of an identifier are:<\/p>\n

              \n
            • It can consist of alphabets, digits and\/or underscores.<\/li>\n
            • It must not start with a digit<\/li>\n
            • C++ is case sensitive, that is upper and lower case letters are considered as different from each other.<\/li>\n
            • It should not be a reserved keyword.<\/li>\n<\/ul>\n

              Question 5.
              \nWrite a short note on literals.
              \nAnswer:

              \n\/ division
              \n% modulus
              \nOperations of addition, subtraction, multiplication, and division literally correspond with their respective mathematical operators.
              \nFor example,
              \nsum = 5 + 10;
              \ndifference = 10 – 5;
              \nproduct = 2 * 5;
