a.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 The values of those variables are passed to the function so that it can manipulate them<\/p>\n
b.\u00a0\u00a0\u00a0\u00a0\u00a0 The location of variable in memory is passed to the function so that it can use the same memory area for its processing<\/p>\n
c.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 The function declaration should contain ampersand (&Wink in its type declaration<\/p>\n

\u00a0

b.\u00a0\u00a0\u00a0\u00a0\u00a0 One function containing another one or more functions inside it.<\/p>\n
c.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Two or more functions with the same name but different number of parameters or type.<\/p>\n
d.\u00a0\u00a0\u00a0\u00a0\u00a0 None of above<\/p>\n
\u00a0
Question 9:<\/p>\n
Functions can be declared with default values in parameters. We use default keyword to specify the value of such parameters.<\/p>\n
