How do you do multiple arguments in C++?
Variable number of arguments in C++ Define a function with its last parameter as ellipses and the one just before the ellipses is always an int which will represent the number of arguments. Create a va_list type variable in the function definition. This type is defined in stdarg.

What are the arguments of a function?
These arguments are kind of inputs for the function. For example – A function which is used to add two integer variables, will be having two integer argument. Block of code: Set of C statements, which will be executed whenever a call will be made to the function.
What is argument list in C programming?
argument list: Argument list contains variables names along with their data types. These arguments are kind of inputs for the function. For example – A function which is used to add two integer variables, will be having two integer argument. Block of code: Set of C statements, which will be executed whenever a call will be made to the function.
What is the difference between function_name and argument list?
function_name: It can be anything, however it is advised to have a meaningful name for the functions so that it would be easy to understand the purpose of function just by seeing it’s name. argument list: Argument list contains variables names along with their data types. These arguments are kind of inputs for the function.
Can a function be called without arguments in C?
