这里,对象可以进一步延伸至表达式,即sizeof可以对一个表达式求值,编译器根据表达式的最终结果类型来确定大小,一般不会对表达式进行计算。如: sizeof( 2 ); // 2的类型为int,所以等价于 sizeof( int ); sizeof( 2 + 3.14 ); // 3.14的类型为double,2也会被提升成double类型,所以等价于 sizeof( double )...
1.Python rstrip() 删除string 字符串末尾的指定字符(默认为空格). (1)sizeof sizeof(...)是运算符,在头文件中typedef为unsigned int,其值在编译时即计算好了,参数可以是数组、指针、类型、对象、函数等。 它的功能是:获得保证能容纳实现所建立的最大对象的字节大小。 由于在编译时计算,因此sizeof不能用来返...

我知道这可以由sizeof(array)/sizeof(array[0])完成。然而,我觉得这有点令人困惑。 我希望大数组是2D的(也就是1D数组的不同表示),这个大数组中的每个字符数组所占的字节数与这个大数组中字符数组的最大大小相同。下面的例子 #include <stdio.h> #include <string.h> const char *words[] = {"this","...
