请帮忙看一下代码！！跪谢！！！！


#include <stdio.h>
#include <string.h>
#include <stdlib.h>

struct node 
{
	char str[20]; 
	char s[20];
};

int cmp( const void *a, const void *b )
{
	return strcmp( (( struct node * ) a)->s ,  (( struct node * ) b)->s );
}

int bcmp( const void *a, const void *b )
{
	return strcmp( ( char * )a , (( struct node * ) b)->s );
}
struct node t[10110];
int main(void)
{
	
	char a[100], b[100]; 
	char str[100];
	int flag;
	int u;
	int i;

	int n;

	u = 0;

	while( gets( a ), a[0] != '\0' )
	{
		i = 0;
		n = strlen(a);
		a[n] = '\0';
		
		while( a[i] != ' ' )
		{
			b[i] = a[i];
			i++;
		}
		b[i] = '\0';
		a[i] = '\0';
		i++;
		while( a[i] == ' ' )
		{
			i++;
		}

		//strcpy( b, (a + i) );

		
		strcpy( t[u].str, b);
		strcpy( t[u].s, a+i );
		u++;
	}

	qsort( t, u, sizeof( struct node ), cmp );

	while( scanf("%s", str ) != EOF )
	{
		flag = 0;
		
		char *p;

		if( p = ( char * )bsearch( str, t, u, sizeof( struct node ), bcmp ), p != NULL )
		{
			printf("%s\n", p );
			flag = 1;
		}

		if( flag == 0 )
			printf("eh\n");
		i++;
	}


	return 0;

}
