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 ); sizeof也可以对一个函数调用求值,其结果是函数返回类型的大小,函数并不会被调用,我们来看一个完整的例子: char foo() {
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(int)<<endl;// sizeof(typename)的用法,合理 cout<<sizeof...
Thesizeofkeyword gives the amount of storage, in bytes, associated with a variable or a type (including aggregate types). This keyword returns a value of typesize_t. The expression is either an identifier or a type-cast expression (a type specifier enclosed in parentheses). When applied to ...
int flag = 1; char in_buf[MESSAGE_SIZE] = {0,}; struct sockaddr_in local_addr, remote_addr; //create a tcp socket socket_fd = socket(AF_INET,SOCK_STREAM,0); if (socket_fd==-1){ perror("create socket error"); exit(1); } //set option of socket ret = setsockopt(socket_fd,...
Understanding the memory usage of Python objects proves to be invaluable, especially in scenarios where memory optimization is paramount. The `sys.getsizeof()` function serves as an initial tool to estimate the size of basic data types and simple data structures. ...
A total of 2,520 sand samples, obtained from grain size analysis, were used in this study. The primary aim is to predict sand grain sizes using machine learning and deep learning algorithms. The input data consists of the five grain size fractions of sands based on the Udden-Wentworth ...
Now let's change the order of data member in the derived class and check the size of the class & object. Example #include <bits/stdc++.h>usingnamespacestd;classBase{protected:staticinti;inta;charb;public:Base() { a=0; b='#'; } Base(intaa,charbb) { a=aa; b=...
