As said above, numerous issues [10] with printf()'s lack of type safety resulted in the revision [11] of approach to formatting, and C++20 an onwards include format specifications in the language [12] to enable type-safe formatting. The approach (and syntax) of C++20 std::format resulted from effectively incorporating Victor Zverovich's libfmt ...

The C programming language provides many standard library functions for file input and output.These functions make up the bulk of the C standard library header <stdio.h>. [1] The functionality descends from a "portable I/O package" written by Mike Lesk at Bell Labs in the early 1970s, [2] and officially became part of the Unix operating system in Version 7.
GNU Emacs comes with two ctags utilities, etags and ctags, which are compiled from the same source code. Etags generates a tag table file for Emacs, while the ctags command is used to create a similar table in a format understood by vi. They have different sets of command line options: etags does not recognize and ignores options which only ...
Microsoft Visual Studio uses PDB files as its primary file format for debugging information. Another use of PDB files is in services that collect crash data from users and relate it to the specific parts of the source code that cause (or are involved in) the crash.
