Is there an analogue of the function cin.peek () in C? Or do you have to read the symbol from the stream in C, and then return it?

    There is no analog. You need to write yourself:

    /* return the next character from stdin without consuming it */ int peekchar(void) { int c = getchar(); if (c != EOF) ungetc(c, stdin); /* puts it back */ return c; }

     int fpeek(FILE *stream){ int c = fgetc(stream); ungetc(c, stream); return c; }
