可能重复:
  Program isn't printing correctly.

的#include

包括// toupper功能所需

include //需要退出文件

                            continue;

                    if (taxExemptions > 12  || taxExemptions < 0) 
                    {
                        printf("\n %d     **** Invalid number of exemptions ****", taxpayerId);
                    } 
                    else 
                    {
                        taxAmount = taxableIncome * taxRate;
                        printf("\n %d %15.2f  %15.2f  %18.2f",taxpayerId,taxableIncome,taxRate,taxAmount);
                    }  





}

fclose(tax);// close file tax
scanf("%d",&holdScreen);
return 0;

}

输出应该看起来像这样,但它不能正常工作。我认为它与if语句和's'||没有关系's''''|| 'M'|| 'j'|| 'J'。
