编写一个C程序,声明三个名为price,quantity和amount的一维数组

Write a C program that declares three one-dimensional arays named price, quantity, and amount. Each aray should be capable of holdinc
10 elements. Using a for loop, input values for the price and quantity rays. Theentries in the amount array should be product of the
corresponding values in the price and quantity arrays (thus,amountli=price[il*quantityli). After al of the data has been entered, display the
following output:
Quantity Price
Amount
Under each column heading display the appropriate value

定义三个一维数组，遍历数组输入和输出，

代码如下：

#include <stdio.h>
int main()
{
    double price[10], amount[10];
    int quantity[10], i;
    for (i = 0; i < 10; i++)
    {
        printf("请输入第%d组数据（价格 数量）:", i + 1);
        scanf("%lf %d", &price[i], &quantity[i]);
        amount[i] = price[i] * quantity[i];
    }

    printf("%10s %8s %8s\n", "Quantity", "Price", "Amount");
    for (i = 0; i < 10; i++)
        printf("%10d %8.2f %8.2f\n", quantity[i], price[i], amount[i]);
    return 0;
}

#include <stdio.h>
void main()
{
    double price[10];
    int quantity[10];
    double amount[10];
    int i;
    printf("please input 10 prices:\n");
    for(i=0;i<10;i++)
        scanf("%lf",&price[i]);
    printf("please input 10 quantity:\n");
    for(i=0;i<10;i++)
    {
        scanf("%d",&quantity[i]);
        amount[i] = quantity[i] * price[i];
    }
    printf("%-15s%-15s%-15s\n","Price","Quantity","Amount");
    for(int i=0;i<10;i++)
        printf("%-15.1f%-15d%-15.1f\n",price[i],quantity[i],amount[i]);
    return 0;
}

#include<stdio.h>
int main()
{
    float price[10],quanity[10],amount[10];
    int i;
    printf("请输入价格和数量:\n");
    for(i=0;i<10;i++)
    {
        scanf("%f",&price[i]);
        scanf("%f",&quanity[i]);
    }
    for(i=0;i<10;i++)
        amount[i]=price[i]*quanity[i];
    for(i=0;i<10;i++)
        printf("%f ",amount[i]);
    return 0;
}
