This question requires writing a function to move the first 3 characters of the input string to the end.
Function interface definition:
void Shift( char s[] );
Among them char s[]is the string passed in by the user, and the length of the title is guaranteed to be no less than 3; the function Shiftmust still exist s[]in the string after the transformation according to the requirements .
Sample referee test procedure:
#include <stdio.h>
#include <string.h>
#define MAXS 10
void Shift( char s[] );
void GetString( char s[] ); /* 实现细节在此不表 */
int main()
{
char s[MAXS];
GetString(s);
Shift(s);
printf("%s\n", s);
return 0;
}
/* 你的代码将被嵌在这里 */
Input sample:
abcdef
Sample output:
defabc//1. If you have any questions, please leave a message to point out, thanks! ! !
//2. If you have a better idea, you are also welcome to leave a message, thank you! ! !
void Shift( char s[])
{int i,j,k,n;
n=strlen(s);// strlen() is used to calculate the length of the specified string s, excluding the end character "\0".
for(i=0;i<3;i++)//Move the first 3 characters of the input string to the end, that is, loop three times
{k=s[0];//Take the first element out
for( j=1;j<n;j++)//From the second one, assign the previous value
s[j-1]=s[j];
s[n-1]=k;//The number will be taken out Move to the end
}
}
