如何使我的支票生成器输出确切的输出，而不是“零".在C中 [英] How to make my cheque generator output exactly what it is instead of "Zero" in C
问题描述
我的Check生成器程序可以完美地处理您输入的任何内容，以使其输出以字为单位的数字.例如，如果我输入"1234.56"，它将输出一千三百二十四美元和... 56美分".但是，每当我要输出"1000"之类的内容时，它都会输出一千零美元和... 0美分".显然不是1000零美元，美分完全可以，但是我希望摆脱那个零"，但是我需要在那儿输入一些时间，例如如果您键入"0.01"，它将输出零美元和1分".
My Cheque generator program has worked flawlessly for any input you give it to make it output the numerals in words. for example if I were to input "1234.56" it will out put "One Thousand Two Hundred Thirty Four Dollars and ... 56 Cents". However whenever I want to output something like "1000" it will output "One Thousand Zero Dollars and ... 0 Cents". Obviously its not 1000 Zero dollars, The cents are perfectly fine, however I wish to get rid of that "Zero" but I need that in there for moments such as if you were to type in "0.01" It would output "Zero Dollars and 1 Cent".
代码如下:
#include <stdio.h>
void printNum(int);
void printNum2(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 $0.01 to $9999.99 inclusive: ");
scanf("%f", &inclusive);
if(inclusive < 0.00 || 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;
/*Printing if the variables are in the thousands, hundreds, tens or ones categories.*/
if (a > 0){
printNum(a);
printf("Thousand ");
}
if (b > 0){
printNum(b);
printf("Hundred ");
}
printNum2(c);
if (d > 0){
printNum(d);
printf("Dollars and ... ");
}
else if (d == 0){
printf("Zero 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 == 4)
printf("Four ");
else if (x == 5)
printf("Five ");
else if (x == 6)
printf("Six ");
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)
printf("Ten ");
else if ( x == 11)
printf("Eleven ");
else if ( x == 12)
printf("Twelve ");
else if ( x == 13)
printf("Thirteen ");
else if (x == 14)
printf("Fourteen ");
else if (x == 15)
printf("Fifteen ");
else if (x == 16)
printf("Sixteen ");
else if (x == 17)
printf("Seventeen ");
else if (x == 18)
printf("Eighteen ");
else if (x == 19)
printf("Ninteen ");
else if (x == 2)
printf("Twenty ");
else if (x == 3)
printf("Thirty ");
else if (x == 4)
printf("Forty ");
else if (x == 5)
printf("Fifty ");
else if (x == 6)
printf("Sixty ");
else if (x == 7)
printf("Seventy ");
else if (x == 8)
printf("Eighty ");
else if (x == 9)
printf("Ninety ");
}
推荐答案
像 inclusive = inclusive-(c * 10)之类的各种减法都出现舍入误差，因此，当做 if(d> 0).
Various subtractions like inclusive = inclusive - (c*10) are suffering round-off error and therefore have a tiny amount left when doing if (d > 0).
建议四舍五入到最接近的0.01.例如: inclusive = round(100 *(inclusive-(c * 10)))/100.0 等位置.
Suggest rounding to nearest 0.01. Example: inclusive = round(100*(inclusive - (c*10)))/100.0 and other places.
或全部以整数分做.
