C语言中二维数组看作一维数组的排序

Question

#include <stdio.h> 
#include <string.h> 
void main(){
    char a[6][7]={"Tom","Mary","Jack","Rose","Harry","Alice"};
    int i,j;
    char t[7];
    for(i=0;i<6;i++)
    for(j=0;j<5-i;j++)
    if(strcmp(a[j],a[j+1])>0) {strcpy(t[7],a[j]);strcpy(a[j],a[j+1]);strcpy(a[j+1],t[7]);}
    else break;
    for(i=0;i<6;i++)
    printf("%s\n",a[i]);
}

Answer 1

• 先看效果：

• 修改如下：

#include <stdio.h> 
#include <string.h> 
int main(){
    char a[6][7]={"Tom","Mary","Jack","Rose","Harry","Alice"};
    int i,j;
    char t[7];
    for(i=0;i<5;i++)
        for(j=0;j<5-i;j++)
            if(strcmp(a[j],a[j+1])>0) 
            {
                strcpy(t,a[j]);
                strcpy(a[j],a[j+1]);
                strcpy(a[j+1],t);
            }
    
    for(i=0;i<6;i++)
        printf("%s\n",a[i]);
    return 0;
}
