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...
cout<<sizeof(i)<<endl; // sizeof(object)的用法,合理 cout<<sizeof i<<endl; // sizeof object的用法,合理 cout<<sizeof 2<<endl; // 2被解析成int类型的object, sizeof object的用法,合理 cout<<sizeof(2)<<endl; // 2被解析成int类型的object, sizeof(object)的用法,合理 cout<<sizeof(...
