Question

我试图让我的c程序运行你输入的任何值将作为单词出现，例如，如果我想输入值1234.56它应该出来“一千二百三十四美元......” 56分“请注意分数只是数字。到目前为止，我已经正确编写了能够将数字转换为单词的代码，但我不知道如何只留下单独的分数。请帮忙!!

目前，对于小数点，我在否定数字中得到了一些令人发指的数字！

代码如下：

#include <stdio.h>

void printNum(int);
void printNum2(int);
void printNum3(int);
void printNum4(int);
int main()
{

    int a = 0;
    int b = 0;
    int c = 0;
    int d = 0, e=0;

    float inclusive;

    printf("Welcome to the IPC144 Cheque Generator!!\n");
    printf("PAY TO THE ORDER OF... amahmood29 (018359133)\n");
    printf("Enter a monetary value from $0.01 to $9999.99 inclusive: ");
    scanf("%f", &inclusive);

    if(inclusive < 0.01 || inclusive > 9999.99) {
           printf("Sorry, cannot create cheque for that amount, try again next time!\n");
             }
    else
    {                                             
        a = inclusive / 1000;                          //This data is replacing our variable by diving whatever the value is by either 1000, 100, 10.
        inclusive = inclusive - (a*1000);
        b = inclusive / 100; 
                inclusive = inclusive - (b*100);
        if ( inclusive > 19 )
        {
                    c = inclusive / 10;
            inclusive = inclusive - (c*10);
        }
        else
        {
            c = inclusive;
            d = 0;
        }
        d = inclusive;
        e = inclusive; //the variable "e" is for the decimal//
        inclusive = inclusive - a - b - c

        printNum(a);  //Printing is the variables are in the thousands, hundreds, tens or ones categories.//
        printf("Thousand ");
        printNum(b);
        printf("Hundred ");
        printNum2(c);
        printf("");
        printNum3(d);
        printf("Dollars and ... ");
        printNum4(e);
        printf("Cents\n");

    }
}

Answer 1

为避免int和float之间的混淆，并避免两种类型之间的算术运算问题，我建议

scan()输入为float / double。
使用sprintf()将其转换为字符串。
根据分隔符.（小数点）使用strtok()对字符串进行标记。
第一部分（令牌）是不可分割的部分，使用转换器功能进行翻译。
第二部分（标记）是表示“美分”的部分。您可以直接打印。

Answer 2

您可以使用FLOOR功能（舍入到最接近实际值的最接近的整数值），单独打印并从原始数字中减去它 - ＆gt;然后你将得到美分值，你可以乘以100得到它们的整数值。

Answer 3

您正在隐式地将浮点数转换为int。分配e =包含时。这就是为什么你得到奇怪的数字，不要将整数转换为浮点数，反之亦然，永远不要！

实际上你可以使用modulo获得小数部分。

也许你可以试试这个：

void printNum4(float inclusive) 
{
  //Decimal part * 100 to get cents
  float decimal = fmod(inclusive, 1) * 100;
  //Print a float with a 0 decimal precision
  printf("%.0f", decimal);
}

如何使十进制的值只显示数字？
