1.string-->char *，

　调用string的方法c_str()或者data();

 　　string str = "abc";
 　　char *pChar = (char *)str.data();

2.char *-->string

    char *pTemp = "abcdef";
    string tmpStr(pTemp);

3.string-->char[]

    string str = "abcdefg";
    char p[10];
    int i = 0;
    for (i = 0; i < str.length(); i++)
    {
        p[i] = str[i];
    }
    p[i] = ‘
‘;    

4.char[]-->string

    char p[10] = "abcdefg";
    string str1 = p;
