In Node.js, resource intensive operations such as I/O are performed asynchronously, but have a synchronous counterpart (e.g. there exists a fs.readFile and its counterpart is fs.readFileSync). Since Node is single-threaded, you should be careful when using synchronous operations, because they will...

C++ file I/O is done via streams. The key abstractions are: std::istream for reading text. std::ostream for writing text. std::streambuf for reading or writing characters. Formatted input uses operator>>. Formatted output uses operator<<. Streams use std::locale, e.g., for details ...

#include <stdio.h> /* Include this to use any of the following sections */ FILE *fopen(const char *path, const char *mode); /* Open a stream on the file at path with the specified mode */ FILE *freopen(const char *path, const char *mode, FILE *stream); /* Re-open an existing stream on the...
