用语言描述的三位数

numtostr.c

/* Program E6.1 - print nature language for a number. */
#include <stdio.h>
#include <stdlib.h>

int main(void)
{
	char map[][4] = {"零","一","二","三","四","五","六","七","八","九"};
	int num = 0;
	
	printf("Please enter a three-digit number: ");
	scanf("%d", &num);
	
	if( (num/10) % 10 == 0  )
		printf("%s百零%s\n", map[ (num/100) % 10 ], map[ num % 10 ]);
	else
		printf("%s百%s十%s\n", map[ (num/100) % 10 ], map[ (num/10) % 10 ], map[ num % 10 ]);
	
	return 0;
}

忘了个位为零的情况
