  • The getchar () function in C

    The getchar () function in C

     the function int getchar (void) in library c takes a character (an unsigned char) from stdin. this function is equivalent to the getc function with the parameter stdin.
  • Putchar () function in C

  • The function ungetc () in C

    The function ungetc () in C

     the function int ungetc (int char, file * stream) in the c library standard pushes the char character (an unsigned char) onto the stream given to the next character to be read.
  • Function tmpfile () in C

    Function tmpfile () in C

     function file * tmpfile (void) in standard c library create temporary files in wb + mode. the temporary file created will be automatically deleted when the stream is closed (fclose function) or when the program ends.
  • The function gets () in C

    The function gets () in C

     the char * gets (char * str) function in standard c library reads a line from stdin and stores it inside the string pointed by str. it stops when the end-of-file or newline character is encountered (new line) is read.
  • Function fscanf () in C

    Function fscanf () in C

     the int fscanf function (file * stream, const char * format, ...) in library c reads the input formatted from a stream.
  • Function scanf () in C

    Function scanf () in C

     the function int scanf (const char * format, ...) in library c standard reads input that has been formatted from stdin.
  • The function sscanf () in C

    The function sscanf () in C

     the function int sscanf (const char * str, const char * format, ...) in library c standard reads the input formatted from a string.
  • Function fputs () in C

    Function fputs () in C

     the function int fputs (const char * str, file * stream) in the standard c library writes a string to the specified stream (not writing null characters).
  • Function feof () in C

    Function feof () in C

     the int feof function (file * stream) in the standard library c checks the end-of-file indicator for the given stream.
  • Function freopen () in C

    Function freopen () in C

     function file * freopen (const char * filename, const char * mode, file * stream) in library c attaches a new filename with the given stream and at the same time closes the old file in stream.
