No. For example, function getpid never requires a parameter.
Can you have in-out parameter in a function if not then why?
because function have return sts thatway it is not necessary out parameter to function
What is parameter is parameter is?
formal parameter is we accept in function body/defination actual parameter is we pass from calling function to function body. Ex : int a,b; void add (a,b) ; where a & b is actual parameter // calling function void add(int i,int j) where i & j are formal parameter // function body { } By Darshan Paliwal
What is call by refrence?
When calling a function, passing a variable's address as function parameter.
What is an actual parameter?
A formal perimeter refers to an identifier that is used in a method to stand for the value that is passed into the method by a caller. An actual perimeter on the other hand refers to the actual value that is passed into the method by a caller.
What does the cons function do in clojure?
Returns a new sequence where the first parameter is the first element and the second parameter is the rest.
What is the intuition behind the envelope theorem?
The envelope theorem states that the derivative of the value function with respect to a parameter is equal to the partial derivative of the value function with respect to that parameter, evaluated at the optimal values of the control variables. In simpler terms, it tells us that the change in the value function due to a small change in a parameter is equal to the change in the value function that would occur if the control variables were adjusted to keep the parameter constant.
What is Call by value?
when the function is call by value,u are making any changes in formal parameter does not reflect the actuasl parameter.
How to get the date difference in oracle?
by using months_between() function
Why void is used in c language?

How do I use the IF function?
The IF function takes three parameters. The first is an expression, such as an inequality, that will evaluate to either true or false. If the expression is true the second parameter is used, otherwise the third parameter is used.
