把数组里的单词倒置

C

int main()
{
    char *week[7] = {"monday",
                    "tuesday",
                    "wednesday",
                    "thur",
                    "friday",
                    "satur",
                    "sunday"  };
    char week1[7][10] = {};
    for (int i=0; i<7; ++i) {
//        printf("1111%p\n", &i);
        strcpy(week1[i], week[i]);
    }
    //将字符串中每个字母倒置
    for (int i=0; i<7; ++i) {
//        printf("2222%p\n", &i);
        int len = (int)strlen(week1[i]);
        for (int j=0; j<len/2; ++j) {
            printf("%p\n", &j);
            char temp  = week1[i][j];
            week1[i][j]= week1[i][len-1-j];
            week1[i][len-1-j] = temp;
        }
    }
    for (int i=0; i<7; ++i) {
//        printf("3333%p\n", &i);
        printf("%s\n", week1[i]);
    }
}

• 这里定义了一个指针数组，数组里有7个元素，每个元素都是一个字符串指针，

char *week[7] = {"monday",
                    "tuesday",
                    "wednesday",
                    "thur",
                    "friday",
                    "satur",
                    "sunday"  };
