inline std::string ToString(double const value, unsigned const precision = 6) { std::string result; Format(result, "%.*f", precision, value); return result; } ASSERT("123.46" == ToString(123.456, 2)); 为性能痴迷,这种专门的转换函数也是很容易进一步优化,因为所需的缓冲区大小是可以预测的但...
pa,a,&a[0]均指向同一单元,它们是数组a的首地址,也是0 号元素a[0]的首地址。pa+1,a+1,&a[1]均指向1号元素a[1]。类推可知a+i,a+i,&a[i] 指向i号元素a[i]。应该说明的是pa是变量,而a,&a[i]都是常量。在编程时应予以注意。 main(){ int a[5],i; for(i=0;i<5;i++){ a[i]=i...

答案是 A 和 C 这是因为首先函数指针定义时可以没有参数，但是在调用的时候可以加上参数，所以double(*f)()以及后面的(*f)(x)是没问题的，其次，调用newprint时，传递给函数的参数x在newprint中被传递给了f，所以答案A输出的是0.5的正弦值。为什么C也是正确的呢，因为sin和&sin都表示函数sin的...

默认实型:sizeof(22.2) 默认是double实型,占8个字节(B)字符常量:char 占用4个字节字符串常量:char*第一个“双撇号”中什么都不写,即"" (则只有 '\0' 一个字符),所以只占一字节。 第二个"a"中有1 个可见字符,占 2 字节。 第三个"CHINA"有5 个可见字符,占 6 字节。 第四个"How are you"中...
