一个师兄在面试我的时候问了这么一个C问题，是MSDN上的一个例子。能正常编译和运行，偶坚持说没错，但师兄却说有，并且是初级C程序员容易犯的错误！！请各位C code 高手秋秋，究竟有没有错！！

Copy code

/* SCANF.C: This program uses the scanf and wscanf functions
  * to read formatted input.
  */

#include <stdio.h>

void main( void )
{
  int  i, result;
  float fp;
  char  c, s[81];
  wchar_t wc, ws[81];

  printf( "\n\nEnter an int, a float, two chars and two strings\n");

  result = scanf( "%d %f %c %C %s %S", &i, &fp, &c, &wc, s, ws );
  printf( "\nThe number of fields input is %d\n", result );
  printf( "The contents are: %d %f %c %C %s %S\n", i, fp, c, wc, s, ws);

  wprintf( L"\n\nEnter an int, a float, two chars and two strings\n");

  result = wscanf( L"%d %f %hc %lc %S %ls", &i, &fp, &c, &wc, s, ws );
  wprintf( L"\nThe number of fields input is %d\n", result );
  wprintf( L"The contents are: %d %f %C %c %hs %s\n", i, fp, c, wc, s, ws);
}

这个确实是msdn上scanf、wscanf的示例
