The C language implements the left-handed string

------------------------------------------------------------------------------------------

For example: string: AABCD one character to the left: ABCDA

L Two characters: Bcdaa

------------------------------------------------------------------------------------------

C Language code:

# include <stdio.h># include <stdlib.h># include <string.h>#  define max 20void contra_solem (Char *str, int move) {     char *pstart = NULL;    char *pend = NULL;     char *src = NULL;    int i = 0;     pstart = str;    pend =  (Str + strlen (str));     src = str;    for  (i = 0; i  < move; i++)     {        *pend++  = *pstart++;     }    while  (pstart <=  pend)     {        *src = *pstart;       &Nbsp; pstart++;        src++;     }}int  main () {    char str[max] =  "ABCDEFGH";     int  move = 0;                             printf ("source string:%s\n", str);     printf ("Enter the number of characters you want left-handed:"),     scanf ("%d",  &move);                      while  (Move > strlen (str))     {printf ("@@@ 输入 too big, please re-enter!") @@@\n "); scanf ("%d ", &move);     }    contra_solem (Str,move);     printf ("The string after the left%d character is:%s\n", move,str);     system ("Pause");     return 0;}

Work Tip: There is no bool type in C, with an if (bool) or if (!bool) when comparing the bool type with the 0 value;
