In this article we will be discussing how we can quickly merge two sorted arrays using std::merge() function in C++ STL.So, before solving the problem let's first discuss the std::merge() in C++ STL.What is std::merge()?std::merge() function is an inbuilt function in C++ STL, which is defined in the header file. merge() is used to merge two sorted ranges or series. This function combines two sorted ranges to make one single sorted range. All the elements are compared using less than operator (

In this article we will be discussing the working, syntax and examples of quick_exit() function in C++ STL.What is quick_exit()?quick_exit() function is an inbuilt function in C++ STL, which is defined in the header file. quick_exit() function is used to quickly terminate the calling process means it terminates the process without cleaning of its resources.This function is used for normal termination and no additional cleanup tasks are being performed like, no object destructors are called, whereas the C streams are closed or flushed, the files which are opened with tmpfile are being removed.When we terminate a process using quick_exit() ...

In this article we will be discussing the working, syntax and examples of putwchar() function in C++ STL.What is putwchar()?putwchar() function is an inbuilt function in C++ STL, which is defined in the header file. putwchar() function is used to write the wide character on the standard output device. This function takes the wide character from the arguments and writes it on the stdout or standard output of the system.This function is a wide character version of putchar() which is defined in the header file.Syntaxputwchar( wchar_t widec );ParametersThe function accepts following parameter(s) −widec − The wide character which ...

In this article we will be discussing the working, syntax and examples of std::mbrtoc32() function in C++ STL.What is std::mbrtoc32()?std::mbrtoc32() function is an inbuilt function in C++ STL, which is defined in header file. This function is used to convert a narrow multibyte character to UTF-32-character representation.If the associated character pointer is not null, and all other parameters are also accepted then it will convert the corresponding 32-bit character.Syntaxsize_t mbrtoc32( char32_t* pc32, char* str, size_t n, mbstate_t* ps);ParametersThe function accepts following parameter(s) −pc32 − This is the pointer to the location we want the output to be stored.str − ...

In this article we will be discussing the working, syntax and examples of std::mbsrtowcs() function in C++ STL.What is std::mbsrtowcs()?std::mbsrtowcs() function is an inbuilt function in C++ STL, which is defined in the header file. mbsrtowcs() means that it converts the null terminated multibyte character string whose first byte is *src to its wide character representation. This function returns the value according to the conversion.Syntaxsize_t mbsrtowcs( wchar_t* pwc, char** str, size_t n, mbstate_t* ps);ParametersThe function accepts following parameter(s) −pwc − This is the pointer to the location we want the output to be stored.str − Character string which is ...

In this article we will be discussing the working, syntax and examples of memcpy() function in C++ STL.What is memcpy()?memcpy() function is an inbuilt function in C++ STL, which is defined in header file. memcpy() function is used to copy blocks of memory. This function is used to copy the number of values from one memory location to another.The result of the function is a binary copy of the data. This function doesn’t check for any terminating source or any terminating null character, it just copies the num bytes from the source.Examplevoid memcpy( void* destination, void* source, size_t num);ParametersThe ...
