PAT Advanced 1005. Spell It Righ

我的PAT系列文章更新重心已移至Github，欢迎来看PAT题解的小伙伴请到Github Pages浏览最新内容。此处文章目前已更新至与Github Pages同步。欢迎star我的repo。

题目

Given a non-negative integer , your task is to compute the sum of all the
digits of , and output every digit of the sum in English.

Input Specification:

Each input file contains one test case. Each case occupies one line which
contains an ( ).

Output Specification:

For each test case, output in one line the digits of the sum in English words.
There must be one space between two consecutive words, but no extra space at
the end of a line.

Sample Input:

12345

Sample Output:

one five

思路

和PAT Basic 1002. 写出这个数 (20)（C语言实现）几乎是一样的，只不过将拼音变成了英语。

代码

#include <stdio.h>

int main()
{
    int sum = 0;
    char c, *digits[] = {
        "zero", "one", "two", "three", "four", "five",
        "six", "seven", "eight", "nine"
    };

    while((c = getchar()) != '\n')
        sum += c - '0';

    if(sum >= 100)
        printf("%s ", digits[sum / 100]);
    if(sum >= 10)
        printf("%s ", digits[sum % 100 / 10]);
    printf("%s", digits[sum % 10]);

    return 0;
}
