Complete the missing part of the following code. You should create your own data if necessary! Try to understand what this code is doing! /* Figure 8.15 Implementation of scanline Function Using getchar */ /* * Gets one line of data from standard input. Returns an empty string on * end of file. If data line will not fit in allotted space, stores * portion that does fit and discards rest of input line. */ char * scanline(char *dest, /* output - destination string */ int dest_len) /* input - space available in dest */ { int i, ch;

/* Gets next line one character at a time. */ i = 0; for (ch = getchar(); ch != ' ' && ch != EOF && i < dest_len - 1; ch = getchar()) dest[i++] = ch; dest[i] = '\0';

/* Discards any characters that remain on input line */ while (ch != ' ' && ch != EOF) ch = getchar();

return (dest); } C language
