freadis a C standard library function, not a C++ function. It is used for reading binary data from a file in C. Syntax: size_tfread(void*ptr,size_t size,size_t count,FILE*stream); ptr: Pointer to the block of memory where data will be read into. ...
false - if the file pointer doesn't point to the end of the file For example, // variable to store file content string line; // loop until the end of the file while (!my_file.eof()) { // store the current line of the file // in the "line" variable getline(my_file, line)...
[out, optional] lpNewFilePointer 要接收新檔案指標之變數的指標。 如果此參數為NULL,則不會傳回新的檔案指標。 [in] dwMoveMethod 檔案指標移動的起點。 此參數可以是下列其中一個值。 值意義 FILE_BEGIN 0 起點為零或檔案的開頭。 如果指定這個旗標,liDistanceToMove參數會解譯為不帶正負號的值。

[out] Pointer to the file name. If the object has a valid file name, the file name is returned as the ppszFilename out parameter. If the object is in the untitled state, null is returned as the ppszFilename out parameter. Note This result differs from that of the standard GetCurFi...
The following code chunk is enough to include every header file needed to be linked in the program. #include <bits/stdc++.h> using namespace std; Like you don't need to put your time on writing & finding each header file to be mentioned, instead, just add this piece of code chunk....
