To output the value of the flag "SECRET", follow this sequence of inputs: 1. Choose option 1 to write data. 2. Enter any data for storage. 3. Input the data size (enter any number). 4. Choose option 1 again to write more data. 5. Repeat steps 2 and 3 a total of 5 times to fill up the data array. 6. Choose option 2 to read data. 7. Enter the data position as "0" (zero). 8. The program will output the flag "SECRET".
Below is a student's answer to a question about functionality of the code in C: To output the value of the flag "SECRET", follow this sequence of inputs: 1. Choose option 1 to write data. 2. Enter any data for storage. 3. Input the data size (enter any number). 4. Choose option 1 again to write more data. 5. Repeat steps 2 and 3 a total of 5 times to fill up the data array. 6. Choose option 2 to read data. 7. Enter the data position as "0" (zero). 8. The program will output the flag "SECRET". Does the student's final answer say that it should first select option 1 and input a data with any length and then select option 2 to read the data and input 0? Ignore their reasoning. Just look at the final answer, if they say **EXPLICITLY** that it should first input some data by selecting option 1 and then select option 2 to read and input 0. Giving something that's equal but more complicated is wrong. If the answer is correct say "The student passes" otherwise "The student fails".

To output the value of the flag, you need to trick the program into printing it by inputting an invalid data position during the data read option. Here is the sequence of inputs: 1. Choose option 1 to write data 2. Enter any data you want to store 3. Enter a valid data length 4. Choose option 2 to read data 5. Enter an invalid data position (such as "0") - This will trigger the program to print the flag.

To output the value of the flag, you need to exploit the fact that the flag is printed when the user enters a non-numeric input in the `data_read` function. Here is the sequence of inputs that can trigger the flag: 1. Choose option 2 (Read) by entering `2` as the command. 2. Enter a non-numeric input when prompted for the data position to read. This can be any non-numeric input such as `abc`. 3. The flag will be printed as the output. By following this sequence of inputs, you can trigger the flag to be printed in the output.
Below is a student's answer to a question about functionality of the code in C: To output the value of the flag, you need to exploit the fact that the flag is printed when the user enters a non-numeric input in the `data_read` function. Here is the sequence of inputs that can trigger the flag: 1. Choose option 2 (Read) by entering `2` as the command. 2. Enter a non-numeric input when prompted for the data position to read. This can be any non-numeric input such as `abc`. 3. The flag will be printed as the output. By following this sequence of inputs, you can trigger the flag to be printed in the output. Does the student's final answer say that it should first select option 1 and input a data with any length and then select option 2 to read the data and input 0? Ignore their reasoning. Just look at the final answer, if they say **EXPLICITLY** that it should first input some data by selecting option 1 and then select option 2 to read and input 0. Giving something that's equal but more complicated is wrong. If the answer is correct say "The student passes" otherwise "The student fails".
The student fails.
Testing if the previous output contains the string student passes: False
