Answer / navneet

using Variable length argument lists :
Let us see how

Use vprintf, vfprintf, or vsprintf.

Here is an "error" routine which prints an error message, preceded by the string "error: " and terminated with a newline:

#include <stdio.h>
#include <stdarg.h>

void
error(char *fmt, ...)
{
va_list argp;
fprintf(stderr, "error: ");
va_start(argp, fmt);
vfprintf(stderr, fmt, argp);
va_end(argp);
fprintf(stderr, "\n");
}
To use the older <varargs.h> package, instead of <stdarg.h>, change the function header to:

void error(va_alist)
va_dcl
{
char *fmt;
change the va_start line to

va_start(argp);
and add the line

fmt = va_arg(argp, char *);
between the calls to va_start and vfprintf. (Note that there is no semicolon after va_dcl.)

Is the following code legal? void main() { typedef struct a aType; aType someVariable; struct a { int x; aType *b; }; }
