左旋转字符串

根据 http://blog.csdn.net/v_JULY_v/article/details/6322882 敲的。

 

//main函数开始
main(){
    char str[] = "123456";
    move(str, 6, 4);
    printf("%s \n", str);
}

move(char str[], int length, int x){
    fanZhuan(str, 0, length - x - 1);
    fanZhuan(str, length - x, length - 1);
    fanZhuan(str, 0, length - 1);
}

fanZhuan(char str[], int b, int e){
    char temp;
    for(; b < e; b++, e--){
        temp = str[b];
        str[b] = str[e];
        str[e] = temp;
    }
}
