C语言编写数字输出问题

来源：百度知道 编辑：UC知道 时间：2024/06/01 09:33:36
用C语言编写一个程序，程序的要求是：输入一个数字，数字的范围在0到2,000,000,000之间，然后用英文输出。例如：输入1234011811，输出是：One billion, two hundred and thirty four million, eleven thousand, eight hundred and eleven.
输出的第一个字母要大写，结束要有句号，中间有逗号隔开。

诚心教代码如何编写，要求用C语言。万分感谢。分数必定追加

分太少。给你个idea. 输出 0-99 的方法。大于它的 按 L 判断（你自己写）。大小写尚未考虑。
#include <stdio.h>
#include <stdlib.h>

void main()
{
char s[12];
int d,c,b,a;
char num[20][10]={"zero","one","two","three","four","five","six","seven","eight",
"nine","ten","eleven","twelve","thirteen","fourteen","fifteen","sixteen",
"seventeen","eighteen","ninteen"};
char nty[9][10] = { "ten","twenty","thirty","forty","fifty","sixty","seventy","eighty","ninty"};

int L;
printf("input int number between 0 and 2000000000\n");
scanf("%s",s);
L = strlen(s);
if (L <= 2)
{
sscanf(s,"%d",&a);
if ( a /
