Is there any limitation on string length defined in variable argument list

Question

I have doubt regarding variable argument list,is there any limitation on the lenght of char string defined as one of argument to variable list.for example

void S         


        

Answer 1

There is no limit imposed by the C language on how long a C string can be (as C strings are basically arrays of char with a NUL character at the end). As you can see, the type of the argument is char *, i.e., pointer to char. This means that the string itself is not passed as an argument, but rather a pointer to its first character—the length of the string is therefore irrelevant for the function call.

(In practice there will of course be a limit from the computer architecture and platform, but these limits are very high compared to typical string arguments.)
