C++ inline reference
WebComposes a string with the same text that would be printed if format was used on printf, but instead of being printed, the content is stored as a C string in the buffer pointed by str. The size of the buffer should be large enough to contain the entire resulting string (see snprintf for a safer version). A terminating null character is automatically appended after the content.

Can someone explain this or provide some sources? WebApr 8, 2024 · Syntax of find () The find () function is a member of the string class in C++. It has the following syntax: string::size_type find (const string& str, size_type pos = 0) const noexcept; Let's break down this syntax into its component parts: string::size_type is a data type that represents the size of a string. It is an unsigned integer type.
WebOpens the file identified by argument filename, associating it with the stream object, so that input/output operations are performed on its content.Argument mode specifies the opening mode. If the stream is already associated with a file (i.e., it is already open), calling this function fails. The file association of a stream is kept by its internal stream buffer:
