What does getc mean in C?
C library function – getc() The C library function int getc(FILE *stream) gets the next character (an unsigned char) from the specified stream and advances the position indicator for the stream.
What is the purpose of getc () in C++?
The getc() function in C++ reads the next character from the given input stream. It can be implemented as macro.
What is the difference between fgetc and getc?
The difference between getc and fgetc is that getc can be implemented as a macro, whereas fgetc cannot be implemented as a macro. This means three things: The argument to getc should not be an expression with side effects. Since fgetc is guaranteed to be a function, we can take its address.
What is getc Stdin?
Description. The getc() function reads a single character from the current stream position and advances the stream position to the next character. The getchar() function is identical to getc(stdin) .
Does getc call read?
read is an operating system function, getc is a Standard C macro. It’s up to your compiler (technically, the C standard library implementation used by your compiler) as to whether it implements getc etc. via underlying calls to read , or does something else. getc is a standard C function, not a macro.
Which is true about getc () getc () returns?
The getc() function returns the next character from the input stream pointed to by stream. If the stream is at the end of the file, the end-of-file indicator for the stream is set and getc() returns EOF. If a read error occurs, the error indicator for the stream is set and getc() returns EOF.
What is the purpose of getc () Read a character from stdin read a character from a file read all file read file random?
Answer : read a character from file. getc() returns a character from the specified FILE. The getc() function reads the next character (an unsigned char) from the specified stream and advances the position indicator for the stream. ans is read a character from STDIN.
What is the difference between getc () and getchar ()?
The primary difference between the getchar() and getc() is that the getc() is capable of reading from any input scheme, while the getchar() is capable of reading from the standard input. Hence, getchar() becomes equivalent to the getc(stdin). Here, Syntax: int getchar(void);
What is the return value of getc ()?
RETURN VALUES The getc() function returns the next character from the input stream pointed to by stream. If the stream is at the end of the file, the end-of-file indicator for the stream is set and getc() returns EOF. If a read error occurs, the error indicator for the stream is set and getc() returns EOF.
What is fgetc and fgets?
fgetc(), getc() and getchar() return the character read as an unsigned char cast to an int or EOF on end of file or error. fgets() returns s on success, and NULL on error or when end of file occurs while no characters have been read.
Are getc Stdin and getchar () equivalent?
The function getchar() reads the character from the standard input while getc() reads from the input stream. So, getchar() is equivalent to getc(stdin).
Is getc buffered?
The getc function is a higher level function. It usually uses buffered input (so input is read in blocks into a buffer, sometimes by using read , and the getc function gets its characters from that buffer). It also only returns a single characters at a time.
