字符串怎么能直接赋值？
要用strcpy函数

#include <stdio.h>
#include <string.h>

void maopao(char s[][7]) {
    int i, j;
    char temp[7]={0};

    for(i = 0; i < 5; i++) {
        for(j = 0; j < 4 - i; j++) {
            if(strcmp(s[j], s[j + 1]) < 0) {
                strcpy(temp, s[j]);
                strcpy(s[j], s[j + 1]);
                strcpy(s[j + 1], temp);
            }
        }
    }
}

int main(void) {
    int i;
    char s[5][7] = {"man", "woman", "girl", "boy", "sister"};
    maopao(s);

    for(i = 0; i < 5; i++) {
        puts(s[i]);
    }

    return 0;
}

改了也不对啊，我就是没法运行，你跑一跑试试

不好意思，我想用指针，应该是赋值那一块我不太理解吧

j<5-i吧

#include <stdio.h>
#define LENMAX 7

int scmp(char *sp, char *sq, int lenmax) {
    int i, flag;
    lenmax--;

    for(i = 0; i < lenmax; i++) {
        if(*(sp + i) - * (sq + i) > 0) {
            flag = 1;
            break;

        } else if(*(sp + i) - * (sq + i) < 0) {
            flag = -1;
            break;

        } else {
            flag = 0;
        }
    }

    return flag;
}

void scopy(char *sp, char *sq, int lenmax) {
    int i;
    lenmax--;

    for(i = 0; i < lenmax && *(sq + i) != '\0'; i++) {
        *(sp + i) = *(sq + i);
    }

    *(sp + i) = '\0';
}

void maopao(char s[][LENMAX]) {
    int i, j;
    char temp[LENMAX] = {0};

    for(i = 0; i < 5; i++) {
        for(j = 0; j < 4 - i; j++) {
            if(scmp(s[j], s[j + 1], LENMAX) < 0) {
                scopy(temp, s[j], LENMAX);
                scopy(s[j], s[j + 1], LENMAX);
                scopy(s[j + 1], temp, LENMAX);
            }
        }
    }
}

int main(void) {
    int i;
    char s[5][LENMAX] = {"man", "woman", "boy", "boys", "sister"};
    maopao(s);

    for(i = 0; i < 5; i++) {
        puts(s[i]);
    }

    return 0;
}

下面是对字符串冒泡排序的一个示例：

// 学生数据结构
struct StudentItem
{
    char   Code[7];         // 编码
    char   Name[21];        // 姓名
    int    Sex;             // 性别
    int    SchoolCode;      // 学院编码
    double Scores[10];      // 课程成绩
};

// 学生数据表结构
struct StudentInfo
{
    size_t Count;
    StudentItem Data[100];
};
extern StudentInfo Students;

// 复制一个学生数据
StudentItem CopyStudent(StudentItem* source)
{
    StudentItem target;

    strcpy_s(target.Code, source->Code);
    strcpy_s(target.Name, source->Name);
    target.Sex = source->Sex;
    target.SchoolCode = source->SchoolCode;
    memcpy_s(target.Scores, sizeof(target.Scores), source->Scores, sizeof(source->Scores));

    return target;
}

// 交换两个学生的变量内容
void SwapStudent(StudentItem* s1, StudentItem* s2)
{
    StudentItem temp = CopyStudent(s2);
    *s2 = CopyStudent(s1);
    *s1 = CopyStudent(&temp);
}

// 按姓名排序
void StudentsSortByName(StudentInfo* students)
{
    // 用冒泡法进行排序
    for (size_t i = 0; i < students->Count - 1; ++i)
    {
        for (size_t j = i; j < students->Count; ++j)
        {
            if (strcmp(students->Data[i].Name, students->Data[j].Name) < 0)     // 升序
            {
                SwapStudent(&(students->Data[i]), &(students->Data[j]));
            }
        }
    }
}
