C/C++ Questions only (Variable-Length Argument Lists)
1. I heard that you have to #include <stdio.h> before calling
printf. Why?
2. How can %f be used for both float and double arguments in printf?
3. Why don't function prototypes guard against mismatches in
printf's arguments?
4. How can I write a function that takes a variable number of
arguments?
5. How can I write a function that takes a format string and a
variable number of arguments, like printf, and passes them to printf
to do most of the work?
6. How can I write a function analogous to scanf, that calls scanf
to do most of the work?
7. I have a pre-ANSI compiler, without <stdarg.h>. What can I do?
8. How can I discover how many arguments a function was actually
called with?
9. My compiler isn't letting me declare a function that accepts only
variable arguments.
10. Why isn't "va_arg(argp, float)" working?
11. I can't get va_arg to pull in an argument of type
pointer-to-function.
12. How can I write a function which takes a variable number of
arguments and passes them to some other function ?
13. How can I call a function with an argument list built up at run
time?
