You can have a function with no parameters.
Formal parameters are those that appear in a function's prototype, using the parameter names provided by the function implementation (which may differ from the names used in the function prototype), and that are subsequently used in the function body. Actual parameters are those parameters that are passed by the calling function. Actual parameters are evaluated and passed to the function via its formal arguments.
They are synonyms. They mean the same thing. The arguments of a function are its parameters and vice versa.
a. Functions can have only one parameter. b. The order in which the parameters are defined matters. c. Parameters can be passed to a function in any order. d. Parameters have no order.
The IF function has 3 parameters. The condition, the true part and the false part.
In most languages, you can't have names with space, for functions, variables, etc. Assuming your function is called myFunction, the usual way to call it is: myFunction() This assumes the function requires no parameters. If the function does require parameters, the parameters will be included within parentheses.
It means that the function doesn't have parameters.example:int foo (void); -- it is a prototype for function 'foo', having no parametersint bar (); -- it is not a prototype as it says nothing about the parameters
There is no builtin function 'counta' in C.
You don't 'send input' to a function, you pass parameters. There are functions without parameters, 'getpid' for example.
overloading means same function but different arguments. so with overloading we can take different actions with different parameters....
In function overloading, for different tasks there should be different blocks of codes with the same name to perform different tasks, while default arguments has only one block of code and perform only one task. Function overloading take different types & numbers of argument to perform different tasks, But default arguments perform only one task which has been declared or written for it without weather its called with exact number of parameters called with less number of parameters. but it will perform the same task. Function overloading take the exact number of parameters to work, But default arguments can take exact number of parameter or less number of parameters or even no parameters. it will assign the default values to the parameters and perform the task. Hope it will help you, Please correct if there was mistake. RAMIN SADAT, South Asian University (MSC)
Yes! Using output parameters. A return statement can be used for returning only one value from a function. However, using output parameters, you can return two values from a function.
The formal arguments are the names given to the parameters/arguments in the function declaration. These names will be used within the body of the function. void myFunc( int i, char c ); // Function prototype The actual arguments are the variables and/or constants (those supplied by the caller) that are used when invoking the function. int intVar = 6; char charVar = 'e'; // Actual parameters 3 and 'G' will be mapped to the // formal parameters 'i' and 'c' myFunc( 3, 'G' ); // Execute function // Actual parameters 'intVar' and 'charVar' will be mapped // to the formal parameters 'i' and 'c' myFunc( intVar, charVar ); // Execute function
No. Function overloading only pertains to the type of parameters.

Not possible in C.
No. C function argument are positional.
It allows the compiler to verify that the number and types of the functions parameters are correct when the function is actually called. If the function were called with the wrong number or type of parameters, and no function prototype were supplied, the error would not be discovered until the program was actually run.
The name of the function is established by what is called function declaration. It also establishes the number and the types of parameters.
*Return variable type* *Function Name* (*Function parameters*) For example: int MyFunction (x,y)
it's not a statement, it's a function: len= printf (format, ...more-parameters...);
When a variable is passed by value, the function receives a copy of the variable. When a variable is passed by reference, the function receives a reference, or pointer, to the original data.
