我正在开发一个附加用户数据并将其添加到 csv 格式的文本文件的函数。我的问题是，当它应该提示我输入 char 变量时，它会跳过它并要求我输入产品名称。我的逻辑看起来在这里吗。感谢您提前提供任何帮助。

我的结构如下所示：

struct inventory_s
{
    int productNumber;
    float mfrPrice;
    float retailPrice;
    int numInStock;
    char liveInv;
    char productName[PRODUCTNAME_SZ];
};

int addProduct(void)
{

    struct inventory_s newInventory;

    FILE* inventoryFile = fopen("inventory.txt", "a"); //opens and writes to file
    if (inventoryFile == NULL) //if file is empty
        {
            printf("Could not open data file\n");
            return -1;
        }

    printf(" Please enter the new product number: ");
    scanf(" %i", &newInventory.productNumber);
    //input= 7000
    printf("\nPlease enter the manufacturer's price: ");
    scanf(" %f", &newInventory.mfrPrice);
    //input= 35
    printf("\nPlease enter the retail price: ");
    scanf(" %f", &newInventory.retailPrice);
    //input= 89.99
    printf("\nPlease enter the initial number in stock: ");
    scanf(" %i", &newInventory.numInStock);
    //input= 2
    printf("\nIs this a live animal? (1 for YES or 0 for NO): ");
    scanf(" %c",&newInventory.liveInv);
    //input= 1
    printf("\nPlease enter the new product name (up to 20 characters): ");
    scanf(" %[^\n]s", newInventory.productName);
    //input= Siamese Kitten
    fprintf(inventoryFile,"\n%i, %.2f,%.2f,%i,%c,%s",newInventory.productNumber, newInventory.mfrPrice, newInventory.retailPrice, newInventory.numInStock, newInventory.liveInv, newInventory.productName);
    fclose(inventoryFile);
    return 0;
}

输出：到inventory.txt
