Exercise 8-7 string sorting (20 points)

This question requires the preparation of procedures , Read in 5 A string , Output in order of small to large .

Input format ：

Input is space delimited 5 Non empty strings , Each string does not contain spaces 、 tabs 、 Blank characters such as line breaks , The length is less than 80.

Output format ：

Output the sorted results in the following format ：

After sorted:
 One string per line 

sample input ：

red yellow blue black white

sample output ：

After sorted:
black
blue
red
white
yellow

The code is as follows ：

#include<stdio.h>
int main()
{
    char a[5][80]={'0'};
    char temp[80]={'0'};
    int i,j;
    for(i=0;i<5;i++){
        scanf("%s",&a[i]);
    }
    for(i=0;i<4;i++){// Bubble sort 
        for(j=0;j<4-i;j++){
            if(strcmp(a[j],a[j+1])>0){//strcmp() Function comparison size usage 
                strcpy(temp,a[j]);//strcpy() Usage of copy string 
                strcpy(a[j],a[j+1]);
                strcpy(a[j+1],temp);
            }
        }
    }
      printf("After sorted:\n");  // Print the sorted string   
    for(i=0;i<5;i++){
        printf("%s\n",a[i]);
    }
    return 0;
}

summary ： The difficulty of this question is to check whether it is right strcpy() and strcmp() function , And the skilled application of bubble sorting ;strcpy() and strcmp() If you forget, you can refer to this blog to help recall ：C Language implementation strcpy and strcmp_qq_42820622 The blog of -CSDN Blog _c Language strcmp
