Can you call a function with no arguments?

A function in C can be called either with arguments or without arguments. These function may or may not return values to the calling functions.

What is a function with no argument?

Function with no argument means the called function does not receive any data from calling function and Function with no return value means calling function does not receive any data from the called function. So there is no data transfer between calling and called function.

When arguments are passed by value the function works with the original arguments in the calling program?

Q3. What do you mean by call by value and call by reference argument passing mechanism? Ans- When passing data by value, the data is copied to a local variable/object in the function. Changes to this data are not reflected in the data of the calling function.

What are the arguments given in the function call called?
