在C中读取文件时跳过一行

我有一个包含一些行的文件,例如：

\#comment

\#comment

icecream 5

pizza 10

pie 7

\#comment

tortillas 5
fajitas 5

我希望我的程序只读取不以#开头的行.

FILE *pf;
char first [20],second [20];
pf = fopen("config.conf","r");
if (pf)
{
    while (! feof(pf))
    {
        fscanf(pf,"%s \t ",first);
        while(!strcmp(first,"#")){ `HERE I NEED JUMP TO NEXT LINE`
            fscanf(pf,first);
        }
        fscanf (pf,second);
        printf("Food: %s \t Cost: %s \n",first,second);
    }
    fclose(pf);
}
else
    printf( "Errore nell'aprire config.conf\n");
