C - 与fgets有关

Question

当用户尝试第二次输入数据（跳过第一次输入）时，我遇到fgets问题。第一次正常工作..如下图所示： enter image description here

我正在使用以下代码：

printf("Please Enter Following Information: \n\n\n");
        printf("County (For Example - Hamilton,Ohio): \n");
        fgets(strCounty, 49, stdin);
         /* we should trim newline if there is one */
        if (strCounty[strlen(strCounty) - 1] == '\n') {
            strCounty[strlen(strCounty) - 1] = '\0';
        }
        printf("Race of head of Household (For Example - Asian): \n");
        fgets(strRace, 49, stdin);
        /* again: we should trim newline if there is one */
        if (strRace[strlen(strRace) - 1] == '\n') {
            strRace[strlen(strRace) - 1] = '\0';
        }
        printf("Number in Household: \n"); 
        scanf("%d",&intHouseholds);
        printf("The household yearly income: \n");
        scanf("%d",&dblIncome);
