如何使我的输出仅显示我的 c 支票生成器程序所需的内容

Question

我制作了一个程序，可以输出输入的任何数字，但它会将其转换为单词，而不仅仅是数字，例如，如果您输入“1234.56”，它会将其转换为 "One Thousand Two Hundred Thirty Four Dollars and ... 56 Cents"。美分应始终以数字表示。到目前为止，一切都很好，但是如果我输入的金额少于一千，我会在其中得到多余的词，例如 "Thousand" 或 "Hundred"。例如，如果我输入“15.77”，我的输出将是 "Thousand Hundred Fifteen Dollars and ... 77 Cents"。我不希望有千位或百位，没有它们就完美了！

代码如下：

#include <stdio.h>

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

    int a = 0;
    int b = 0;
    int c = 0;
    int d = 0; 
    int num = 0;
    int printcents; //To convert the float "cents" to an integer.

    float inclusive;
    float cents;

    printf("Welcome to the IPC144 Cheque Generator!!\n");
    printf("PAY TO THE ORDER OF... amahmood29 (018359133)\n");
    printf("Enter a monetary value from [=10=].01 to 99.99 inclusive: ");
    scanf("%f", &inclusive);

    if(inclusive < 0.01 || inclusive >= 10000.00) {
           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 vaulue 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;
        num = inclusive;
        cents = (inclusive - num)*100; //To calculate our "Cents" with numerals.
        printcents = cents;

        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 ... ");
        printf("%d", printcents);
        printf(" Cents\n");

    }
}

void printNum(int x)  //Created functions to easily output various if statements.
{
    if ( x == 1)
        printf("One ");
    else if ( x == 2)
        printf("Two ");
    else if (x == 3)
        printf("Three ");

    else if (x == 7)
        printf("Seven ");
    else if (x == 8)
        printf("Eight ");
    else if (x == 9)
        printf("Nine ");

}
void printNum2(int x)
{
     if ( x == 10)

     else if (x == 8)
         printf("Eighty ");
     else if (x == 9)
         printf("Ninety ");
}

void printNum3(int x)
{
    if ( x == 1)
        printf("One ");
    else if ( x == 2)
        printf("Two ");
    else if (x == 3)
        printf("Three ");
    else if (x == 4)

    else if (x == 6)

    else if (x == 7)
        printf("Seven ");
    else if (x == 8)
        printf("Eight ");
    else if (x == 9)
        printf("Nine ");

}

我已经编码整整一个月了，所以如果看起来我犯了一些简单的错误，那就是原因。

Answer 1

您需要在 printfs 周围添加条件：

if (a > 0)
{
    printNum(a);  //Printing is the variables are in the thousands, hundreds, tens or ones categories.
    printf("Thousand ");
}

Answer 2

问题是你在无条件打印"Thousand"、"Hundred"等...

    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 ... ");
    printf("%d", printcents);
    printf(" Cents\n");

如果您发送给 printNum 的数字为零，您不想打印出您的文本字符串，您必须检查该条件：

/* call to printNum x */
if ( /* check if the parameter to printNum matches any case, seems to be if not zero){
    printf(/* whatever string is appropriate */);
}

Answer 3

举个例子，假设输入是 512.26

512.26/1000 <<< 应该是 512.26/ 1000.f 所以除法的两个操作数都是浮点数

将导致浮点值：0.51226f NOT 0.0f

使用 floor(0.51226f) 将导致 0.0f

建议始终应用 floor() 函数产生 0.0f

即使使用浮点数，也可以进行比较，如 if( value != 0.0f ) 然后打印它

将在应用 floor() 函数后工作。
