#include <stdio.h>

void main( void )
{
   char  tokenstring[] = "15 12 14...";//空格作为不同格式的分割符
   char  s[81];
   char  ss[81];
   char  c;
   char  d;
   int   i;
   float fp;

   /* Input various data from tokenstring: */
   sscanf( tokenstring, "%s", s );
   sscanf( tokenstring, "%c", &c );
   sscanf( tokenstring, "%d", &i );
   sscanf( tokenstring, "%f", &fp );
   sscanf( tokenstring, "%c%c%s", &c,&d,ss );
//注意这一句的结果，c='1',d='5',ss="12"

   /* Output the data read */
   printf( "String    = %s\n", s );
   printf( "Character = %c\n", c );
   printf( "Integer:  = %d\n", i );
   printf( "Real:     = %f\n", fp );
//注意输出结果
 printf( "Character = %c\n", c );
 printf( "Character = %c\n", d );
 printf( "String    = %s\n", ss );
  
}


Output

String    = 15
Character = 1
Integer:  = 15
Real:     = 15.000000

Character = 1
Character = 5
String    = 12
