Passing arguments<\/a> in functions means value given to function<\/a> on which operation is to be performed.<\/p>\n\n\n\n

There are three ways of passing arguments in functions.<\/p>\n\n\n\n

\n
  1. Call by value \/ Pass by Value<\/li>
  2. Call by Reference \/ Pass by Reference<\/li>
  3. Call by Address \/ Pass by Address<\/li><\/ol>\n<\/div><\/div>\n\n\n\n

    Call by value \/ Pass by value<\/h3>\n\n\n\n

    In this type value is passed in function’s argument and operation is done on formal argument.<\/p>\n\n\n\n

    Any change made in formal argument<\/a> does not effect the actual argument.<\/a><\/p>\n\n\n\n

    Q. Write a program to represent call by value for swapping of two variables.<\/a><\/p><\/blockquote>\n\n\n\n
