Exercise 8-8 moving letters

practice 8-8 Moving letters (10 branch )

This problem requires writing functions , The first... Of the input string 3 Move characters to the last .

Function interface definition ：

void Shift( char s[] );

among char s[] Is the string passed in by the user , Ensure that the length of the title is not less than 3; function Shift The string transformed as required must still exist s[] in .

Sample referee test procedure ：

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

#define MAXS 10

void Shift( char s[] );

void GetString( char s[] ); /*  Implementation details are not shown here  */

int main()
{
    char s[MAXS];

    GetString(s);
    Shift(s);
    printf("%s\n", s);
    
    return 0; 
}

/*  Your code will be embedded here  */

sample input ：

abcdef

sample output ：

defabc

void Shift( char s[] ){
    char a[3];
    int j,i;
    for(i=0;i<3;i++){
        a[i]=s[i];
    }
    for(i=3;s[i];i++){
        s[i-3]=s[i];
    }
    for(j=i-3,i=0;i<3;i++){
        s[j++]=a[i];
    }
}
