编程总结2

题目2：币值转换
我的代码：

include <stdio.h>

include <string.h>

void printNumber(char *s, int i, int len);
void printPlace(char *s, int, int);

int main()
{
char s[11];
int i, strLen;

gets(s);
strLen = (int)strlen(s);

if (strLen == 1 && s[0] == '0') {
    printf("a\n");
    return 0;
}

for (i=0; i<strLen; i++) {
    if (s[i] == '0') {
        if (strLen-i == 5) {
            if (s[1]!='0' || s[2]!='0' || s[3]!='0' || s[4]!='0' || strLen < 9) {
                printf("W");
            }
        }
        if (s[i+1] != '0' && s[i+1] != '\0' && (strLen-i != 5)) {
            printf("a");
        }
        continue;
    }else {
        printNumber(s, i, strLen);
        if (strLen-i == 5) {
            if (s[1]!='0' || s[2]!='0' || s[3]!='0' || s[4]!='0' || strLen < 9) {
                printf("W");
            }
        }
    }
    
    if (strLen-i == 9) {
        printf("Y");
    }
}

return 0;

}

void printNumber(char *s, int i, int len)
{
int num = s[i] - '0';

switch (num) {
    case 0:
        printf("a");
        if (s[i] != '0') {
            printPlace(s, len-i, len);
        }
        break;
    case 1: printf("b"); printPlace(s, len-i, len); break;
    case 2: printf("c"); printPlace(s, len-i, len); break;
    case 3: printf("d"); printPlace(s, len-i, len); break;
    case 4: printf("e"); printPlace(s, len-i, len); break;
    case 5: printf("f"); printPlace(s, len-i, len); break;
    case 6: printf("g"); printPlace(s, len-i, len); break;
    case 7: printf("h"); printPlace(s, len-i, len); break;
    case 8: printf("i"); printPlace(s, len-i, len); break;
    case 9: printf("j"); printPlace(s, len-i, len); break;
}

}

void printPlace(char *s, int i, int len)
{
switch (i) {
case 1: break;
case 2: printf("S"); break;
case 3: printf("B"); break;
case 4: printf("Q"); break;
case 5: break;
case 6: printf("S"); break;
case 7: printf("B"); break;
case 8: printf("Q"); break;
}
}
