如何在C中逐一提示輸入？-有解無憂

我對 C 編程很陌生，我對代碼如何提示輸入有疑問。我需要輸入陳述句下的輸入一一來。現在提示的輸出方式是：

To add a new task enter the details below
Name of Task: Science

然后所有其他輸入作為一個組來

Category of Task:
Information about task:
Due Date of Task:
Status of Task
 TD = To-Do
 IP = In Progress
 CT = Completed Task
Enter Status:

但我想先詢問任務的名稱，一旦我輸入該資訊，它應該詢問類別例如：

To add a new task enter the details below
Name of Task:

這是我的代碼：

#include<stdio.h>

int main() {
    char main_choice;
    printf("Welcome to your Task Management System\n");
    printf("What would you like to do today?\n A: Add New Task\n B: View Task \n C: Manage Tasks\n");
    printf("\nEnter your choice:");
    scanf("%c", &main_choice);
    
    if (main_choice == 'A'){
        char name;
        char category;
        char info;
        char date;
        char status;
        printf("\nTo Add a new task enter the details below\n");
        printf("Name of Task:");
        scanf(" %c", &name);
        printf("\nCategory of Task:");
        scanf(" %c", &category);
        printf("Information about task:");
        scanf(" %c", &info);
        printf("Due Date of Task:");
        scanf(" %c", &date);
        printf("Status of Task\nTD = To-Do\nIP = In Progress\nCT = Completed Task\n Enter Status:");
        scanf(" %c", &status);
    }

    return 0;
}

在 C 中使用 scanf 時，您應該在 %c 之前放置一個空格，如下所示：

scanf(" %c", &name);

需要在 %c 之前放置空格以跳過緩沖存盤器中的空白。這樣 %c 匹配給定的字符而不是空格字符。
