C++字符串输入数字输出

#include <iostream>
#include <string.h>
using namespace std;
const char str[][4] = {"yi","er","san","si","wu","liu","qi","ba","jiu"};
const int num[] = {2,2,3,2,2,3,2,2,3};//寻找对应的字符串的大小。
int GetIndex(char *s)
{
    int i = 0;
    for (;i<9;i++)
    {
        if (strncmp(str[i], s,strlen(str[i])) == 0)return i;
    }
}

void Grial(char *str)
{
    char *p = str;
    char *s = new char[11];
    int k = 0;
    while (*p != ‘\0‘)
    {
        int index = GetIndex(p);
        p += num[index];//跳过已经找到的这个数字。
        s[k++] = index + ‘1‘;
        s[k] = ‘\0‘;
    }
    cout << s << endl;//打印。
}

int main()
{
    char *p = new char[100];
    cin >> p;
    Grial(p);
    return 0;
}
