Getchar manual

 · int getchar(); wint_t getwchar(); Return Value. Returns the character read. These functions wait for input and don't return until input is available. To indicate a read error or end-of-file condition, getchar returns EOF, and getwchar returns WEOF. For getchar, use ferror or feof to check for an error or for end of file. Remarks.

NAME top getchar — get a byte from a stdin stream.

getchar() is equivalent to getc(stdin). fgets() reads in at most one less than size characters from stream and stores them into the buffer pointed to by s. Reading stops after an EOF or a newline. If a newline is read, it is stored into the buffer. A terminating null byte ('\0') is stored after the last character in the buffer.

Getchar() function in C. In this section, we will learn the getchar() function in the C programming language. A getchar() function is a non-standard function whose meaning is already defined in the stdin.h header file to accept a single input from the user. In other words, it is the C library function that gets a single character (unsigned char.

do { yylval = (yylval * 10) + (c - '0'); c = getchar(); } while (c >= '0' To avoid this, this manual uses the convention of creating token names in. The macro getchar reads a character from stdin. Return values and error handling is identical to fgetc(). #define putc, (, __c. int getchar (void);. Purpose. Returns the next character from the input stream pointed to by the standard input. If the stream is at end-of-file or a read.
