Write a program in C

You have been dissatisfied with the teaching assistant's question-changing program for a long time, so you now want to make your own question-changing program. However, changing the question-changing program is more difficult than you imagined, so you can only make the AC (accept) part first.

Step 1: Make a program to find the maximum and minimum values of 4 positive integers

The output format is maximum value and minimum value, separated by spaces.

Input (e.g. reading from in.txt):

5 18 7 26

Output:

26 5

Step 2: Store the output in a string.

Step 3: Read all data from the specified file (such as out.txt) and store it in a string

Step 4: Compare the output string and the correct answer string to see if they are exactly the same.

Step 5: Write the specified output in result.txt based on the comparison result.

Enter description:

Enter the input file name in the first line. The file name should be less than 20 characters, assuming it is in.txt.

In the second line, enter the correct file name. The file name should be less than 20 characters, assuming it is out.txt.

in.txt stores 4 positive integers, these 4 positive integers are ints, separated by blanks.

Read the data in in.txt and find the maximum and minimum values of 4 positive integers.

Output description:

Compare the calculated results with the data in out.txt. If they are identical, write AC in result.txt. If there is any difference, write WA in result.txt.

After writing, use the following code to output the contents of result.txt. (Copy and paste this paragraph to the end of your main function, before return 0)

Only the bottom line is the input, the rest are provided or are the results produced after the program is executed.

Example input:

in3_1.txt

out3_1.txt

Example in4_1.txt: (data stored in in3_1.txt)

5 18 7 26

Example out4_1.txt: (data stored in out3_1.txt)

26 5

Example result.txt: (data stored in result.txt)

26 5

Sample output: (Add the code provided above to print out the data stored in result.txt)

AC

Example description:

As long as result.txt is not AC, it means your program is wrong.
