预备知识 库函数<stdarg.h> C语言该头文件定义了变量类型va_list和三个宏，分别是va_start()、va_arg()、va_end(); 主要功能是在函数参数未知的情况下获取函数参数；即下面类型的函数； //参数固定的函数 void add(int total,num1,num2,num3) //参数未知的函数,格式以 ...结束 void add(int total,...) va_list用来定义变量对象 va_start(参数1，参数2)：初始化变量,参数1为变量对象，参数2为传入函数的最后 一个固定参数，即省略号前面的第一个，上面代码就是total va_arg():获取参数 va_end():函数返回 应用： #include<stdarg.h> int Sum(int num, ...) { int i, val = 0; va_list ap; va_start(ap, num); for(i = 0; i < num; i++) { val += va_arg(ap, int); } va_end(ap); return val; } int main() { printf("10, 20, 30的和为 %d\n", Sum(3, 10, 20, 30)); printf("4, 5, 6, 7的和为 %d\n", Sum(4, 4, 5, 6,

0 = 0 1 = 1 ... 9 = 9 10 = a 11 = b ... 35 = z 36 = A 37 = B ... 60 = Z 61 = 10 62 = 11 ... 70 = 19 71 = 1a 72 = 1b I don't know what this is called. Base something? All I want is a function that can convert the numbers into these, and these back to numbers. Is there an easy function that can do this? You may inherit numbers.Number: def baseN(base,alphabet='0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'): class _baseN(numbers.Number): digits=alphabet[:base] def __init__(self,value): if isinstance(value,int): self.value=value if self.value==0: self.string='0' else: tmp=[abs

I'm localizing my app. I have already accomplished Use Base Internationalization and added 1 set language of files: MainStoryboard.strings (French) & InfoPlist.strings (French) which works fine. My problem is that any changes I now make to the MainStoryboard.storyboard (like changing a label field font color) do not reflect the change when I run the app. What am I doing wrong? Can you not change the storyboard attributes once you have done the use base internationalization? Xcode will compile your storyboard to something like MainStoryboard.storyboardc and store the storyboardc file in <Your

数值的整数次方：给定一个double类型的浮点数base和int类型的整数exponent。求base的exponent次方。 保证base和exponent不同时为0 解法一：使用循环来求 分析：注意考虑特殊情况，当底数为0，如果指数是正整数，则可以返回1，如果底数为0，指数是负整数，那么就会出错，而且如果底数不是0，指数是负整数，则返回的应该是底数和正整数运算结果的倒数。因此要考虑齐全。 double PowerWithUnsignedExponent(double base,unsigned int exponent){ double result = 1.0; for(int i=1;i<=exponent;i++) result *= base; return result; } double Power(double base, int exponent) { g_InvalidInput = true; if(base - 0.0 <= 1e-6 && exponent < 0){ g_InvalidInput = false; return 0.0; } unsigned int absExponent = (unsigned int)exponent; if(exponent<0){ absExponent = (unsigned int)(-exponent);

I have a problem with base tag. It looks like <base href="http://myexamplepage.com/myfolder/" /> . Everything works, besides this query: $.get("application/soft/calendar_month_change.php", ...) My computer thinks it's cross domain server and changes query to OPTIONS .... When I remove the base tag, it works correctly but my site doesn't show any images. I use smarty template engine. How can I solve it? How can I solve it? Want my opinion? Don't use base . Exactly for the reason presented here: It creates confusion, and influences other parts of the system in a way that is extremely difficult
