Suppose the individual income tax is: tax rate * (Salary-1600). Please write a program to calculate the income tax payable, where the tax rate is defined as:

• When wages do not exceed 1600, the tax rate is 0;
• When the wage is in the interval (1600, 2500), the tax rate is 5%;
• When the wage is in the interval (2500, 3500), the tax rate is 10%;
• When the wage is in the interval (3500, 4500), the tax rate is 15%;
• When wages exceed 4500, the tax rate is 20%.

  Input format:

  The input gives a non-negative wage in a row.

  Output format:

  Export personal income tax on one line, accurate to 2 digits after the decimal point.

  Input Sample 1:

  1600

  Output Example 1:

  0.00

  Input Sample 2:

  1601

  Output Example 2:

  0.05

  Input Sample 3:

  3000

  Output Example 3:

  140.00

  Input Sample 4:

  4000

  Output Example 4:

  360.00

  Input Sample 5:

  5000

  Output Example 5:

  680.00

The above are the requirements of the topic, the following is the code I wrote

1#include <stdio.h>2 intMain () {3         floatpayroll,tex_rate,sum;4scanf"%f",&Payroll);5 6         if(payroll<= the)7Tex_rate=0;8         Else if(payroll<=2500)9Tex_rate=0.05;Ten         Else if(payroll<=3500) OneTex_rate=0.1; A         Else if(payroll<=4500) -Tex_rate=0.15; -         Else theTex_rate=0.2; - //sum= (Payroll-1600) *tex_rate; -printf"%.2f\n", (payroll- the)*tex_rate); -         return 0; +}

However, instead of passing, the following error message appears:

Show my answer is wrong, I follow the requirements of the topic in the local test, the results are correct. And, I see a similar answer on CSDN's blog, so the reference http://blog.csdn.net/nirvana_wzj/article/details/38677713 is very similar to my idea, Just once every decision to do a output, so I used his code to try, incredibly passed, I am very confused, I hope to be able to explain the problem in the future.
