问题描述

有谁可以告诉我为什么不能编译？


#include< stdio.h>

#include< ctype.h>


void main（）

{


/ *使用相应税率定义的变量。 * /

float fTaxRateDelMar = .0725;

float fTaxRateEncinitas = .075;

float fTaxRateLaJolla = .0775;


/ *为用户计算的变量为要征税的美元金额定义。* /

float fDollarAmount = 0.0;

printf（" \\\
Welcome to Kudler Fine Foods.\\\
;

printf（\ n请输入要征税的小计：）;

scanf（"％f" ;，& fDollarAmount）;


/ *检查用户输入的有效性（数字） - 如果输入无效则返回，如果输入有效则继续* /

int i = isdigit（fDollarAmount）;

而i == 0

{

printf（" \\\
Please输入有效数字："）;

scanf（"％f"& fDollarAmount）;

int i = isdigit（fDollarAmount）;

}


/ *计算变量定义和计算完成。 * /

float fSalesTaxDelMar = fDollarAmount * fTaxRateDelMar;

float fSalesTaxEncinitas = fDollarAmount * fTaxRateEncinitas;

float fSalesTaxLaJolla = fDollarAmount * fTaxRateLaJolla;

float fTotalSaleDelMar = fDollarAmount + fSalesTaxDelMar;

float fTotalSaleEncinitas = fDollarAmount + fSalesTaxEncinitas;

float fTotalSaleLaJolla = fDollarAmount + fSalesTaxLaJolla;


/ *打印报表以显示销售税和总销售额。 * /

printf（\ n在Del Mar商店的$％i的销售税为：$％。2f\ n，fDollarAmount，fSalesTaxDelMar）;

printf（\ n恩西尼塔斯商店$％i的销售税为：$％。2f\ n，fDollarAmount，fSalesTaxEncinitas）;

printf（" \\\
The La Jolla商店$％i的销售税为：$％。2f\ n，fDollarAmount，fSalesTaxLaJolla）;


}

的销售税>

Can anyone tell me why this won''t compile?


#include <stdio.h>
#include <ctype.h>

void main ()
{

/* Variables defined with corresponding tax rates. */
float fTaxRateDelMar = .0725;
float fTaxRateEncinitas = .075;
float fTaxRateLaJolla = .0775;

/* Variable defined for user inputed dollar amount to be taxed.*/
float fDollarAmount = 0.0;
printf("\nWelcome to Kudler Fine Foods.\n");
printf("\nPlease enter the subtotal to be taxed: ");
scanf ("%f", &fDollarAmount);


/* Check validity of user input (number) - return if input is invalid, continue if input is valid */
int i = isdigit(fDollarAmount);
while i==0
{
printf("\nPlease enter a valid number: ");
scanf ("%f", &fDollarAmount);
int i = isdigit(fDollarAmount);
}

/* Calculation variables defined and calculations accomplished. */
float fSalesTaxDelMar = fDollarAmount * fTaxRateDelMar;
float fSalesTaxEncinitas = fDollarAmount * fTaxRateEncinitas;
float fSalesTaxLaJolla = fDollarAmount * fTaxRateLaJolla;
float fTotalSaleDelMar = fDollarAmount + fSalesTaxDelMar;
float fTotalSaleEncinitas = fDollarAmount + fSalesTaxEncinitas;
float fTotalSaleLaJolla = fDollarAmount + fSalesTaxLaJolla;

/* Print statements to display the Sales Tax and Total Sale values. */
printf("\nThe sales tax on $%i at the Del Mar store is: $%.2f\n", fDollarAmount, fSalesTaxDelMar);
printf("\nThe sales tax on $%i at the Encinitas store is: $%.2f\n", fDollarAmount, fSalesTaxEncinitas);
printf("\nThe sales tax on $%i at the La Jolla store is: $%.2f\n", fDollarAmount, fSalesTaxLaJolla);

}
