What is the use of Getchar Mcq?
getchar() function is used to get/read a character from keyboard input.
What is the syntax of Getchar?
C library function – getchar() The C library function int getchar(void) gets a character (an unsigned char) from stdin. This is equivalent to getc with stdin as its argument.

What is the difference between getchar () and Getchar_unlocked () Mcq?
One more difference with getchar() is, it is not a C standard library function, but a POSIX function. It may not work on Windows based compilers. It is a known fact than scanf() is faster than cin and getchar() is faster than scanf() in general. getchar_unlocked() is faster than getchar(), hence fastest of all.
Does Getchar wait for input?
Getchar really does strictly obey its rules. It always gives you the next input character. Any program that enters a loop waiting for some particular input should be designed to survive unexpected end of files.
Can we return Getchar?
The getchar() function obtains a character from stdin. It returns the character that was read in the form of an integer or EOF if an error occurs.
What is the difference between Getchar and gets in C?
The difference between getc() and getchar() is getc() can read from any input stream, but getchar() reads from standard input. So getchar() is equivalent to getc(stdin).
What is the difference between getchar () and getchar unlocked ()?
What does the function getchar () return at the end-of-file?
The getchar function returns the next character from the input stream pointed to by stdin . If the stream is at end-of-file, the end-of-file indicator for the stream is set and getchar returns EOF .
What is EOF equal to?
The End of the File (EOF) indicates the end of input. After we enter the text, if we press ctrl+Z, the text terminates i.e. it indicates the file reached end nothing to read.
Why is Getchar safer than Scanf?
Since it processes more than one characters at each call, scanf() is potentially faster. scanf() is far easier to use – getchar() may be “safer” on its own, but you will have to write a lot of code around it to get some actual functionality out of it.
