[刷题] PTA 7-30 念数字

程序：

#include<stdio.h>
#include<stdlib.h>
#define N 50

int main() {
    char pinyin[][5] = {"ling","yi","er","san","si","wu","liu","qi","ba","jiu"};
    int memory[N] = {0};
    int n,t,i = 0,minus = 0;
    scanf("%d",&n);
    if(n==0) printf("ling");
    if(n<0) {
        minus = 1;
        n = -n;
    }
    if(n>0) {
        while(n!=0) {
            t = n%10;
            n /= 10;
            memory[i] = t;
            i++;
        }
        i--;
        if(minus == 1) printf("fu ");
        for(; i>0; i--) {
            printf("%s ",pinyin[memory[i]]);
        }
        printf("%s",pinyin[memory[i]]);
    }
    return 0;
}

数组存储字符和每位数字，用循环实现倒序输出
