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

Question

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

Answer 1

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;
}
