Library getchar() Function in C++ Programming Language

Library getchar() Function in C++
Get character from stdin. Returns the next character from the standard input (stdin). It is equivalent to calling getc with stdin as argument. The getchar() function is equivalent to a call to getc(stdin). It reads the next character from stdin which is usually the keyboard. getc() can read from any input stream, but getchar() reads from standard input. So getchar() is equivalent to getc(stdin).
Syntax for getchar() Function in C++
#include <cstdio> int getchar ( void );
This function does not accept any parameter. On success, the character read is returned (promoted to an int value). The return type is int to accommodate for the special value EOF, which indicates failure: If the standard input was at the end-of-file, the function returns EOF and sets the eof indicator (feof) of stdin. If some other reading error happens, the function also returns EOF, but sets its error indicator (ferror) instead.

In this, Insert item x into the 'priority queue', maintaining heap order. Return a pointer to the node containing the new item. Find the 'smallest' item in the priority queue. Return

Insert x. Remove x (unimplemented). Return item that matches x. Return "smallest item". Return largest item. Return true if empty or else false. Print tree in sorted order. Return

Insertion sort is simple sorting algorithm that builds the final sorted array ('or list') one item at a time. It is much less efficient on large lists than more advanced algorithms such as quick

In c++ program, a positive integer is asked to enter which is stored in the variable origNum. The number is copied to variable num. This is done because we need to check the origNum
