To retrieve the flag from the provided C code, you need to perform a series of steps through the input prompts. Here’s the sequence of inputs required to output the value of the flag: 1. **Choose to write data:** - Input `1` when prompted to choose an option. 2. **Enter the data for storage:** - Input any string (e.g., `test data`) when prompted to "Enter data for storage". 3. **Input the data size:** - Specify the length of the data you just entered. For example, if you entered `test data`, you could input `9` (the length of the string including space). 4. **Choose to read data:** - Input `2` when prompted to choose an option. 5. **Specify the position from which to read:** - Input `1` (or the appropriate index if you wrote data to more than one position) when asked "Which data position to read?". 6. **Try to read the data:** - If you entered a valid index, it will print the data you stored. 7. **Trigger the condition to display the flag:** - Input `0` when prompted to "Which data position to read?". - This will cause the program to print the flag value because the code has a condition that checks if the entry number is `0` and if so, it prints the flag. ### Summary of Inputs: - `1` (to write data) - `test data` (or any other string) - `9` (or the length of the input string) - `2` (to read data) - `1` (to read from the first position) - `0` (to trigger the flag output) Following these steps will allow you to successfully retrieve the flag from the program.

To retrieve the flag from the provided C code, you need to follow a specific sequence of inputs. The logic in the `data_read()` function allows you to print the flag when you enter a specific entry number that evaluates to `0` when converted to a long integer. Here's the breakdown of the steps you need to follow: 1. **Choose the Write Option (1)**: You will need to write some data into the system first. 2. **Input the Data**: Enter any string as the data you want to store. 3. **Input the Data Size**: Enter a valid positive integer for the size of the data you're writing. 4. **Choose the Read Option (2)**: Once you have written data, you can read it back. 5. **Input the Entry Number**: To get the flag, enter `0`. ### Step-by-step Example: 1. **Write Data**: - Input: `1` (to choose the write option) - Input: `Hello, World!` (or any string you like) (this is the data you are storing) - Input: `13` (this is the length of the data you entered, which is valid) 2. **Read Data**: - Input: `2` (to choose the read option) - Input: `0` (this will trigger the condition in `data_read()` that prints the flag) By following this sequence, you will be able to see the output of the flag. ### Final Input Sequence:

1
Hello, World!
13
2
0

This sequence will successfully lead to the output of `SECRET`, which is your flag.

To retrieve the value of the flag in the provided C code, you need to interact with the program in a specific sequence. The flag is printed when the user enters an invalid data position (specifically, when `entry_number` evaluates to 0 in the `data_read` function). Here's how to achieve that step by step: 1. **Start the program**: When you run the program, you will see the welcome message. 2. **Write data**: Choose the option to write data. This will involve entering some text and then specifying its length. Here’s what you need to do: - Choose option `1` to write data. - Enter some text when prompted for data storage (e.g., "Hello"). - Enter a valid length (e.g., `5` if you entered "Hello"). 3. **Read data**: Now, you will read data. Choose the option to read data: - Choose option `2` to read data. - When prompted for the data position, enter `0` (this is the key step). This will cause the program to print out the flag. 4. **Exit the program**: After the flag is displayed, you can choose option `3` to exit the program. ### Complete Input Sequence: 1. Input: `1` (to write data) 2. Input: `Hello` (or any other string, it must be less than or equal to 100 characters) 3. Input: `5` (length of the string you entered, must match the actual length) 4. Input: `2` (to read data) 5. Input: `0` (this triggers the output of the flag) ### Example: Here’s a full example of how the terminal interaction would look:

Welcome to the Data Echo System!
Choose option (1-Write, 2-Read, 3-Exit):
1
Enter data for storage:
Hello
Input the data size:
5
Data stored at position: 1
Data written. Perform another action?
Choose option (1-Write, 2-Read, 3-Exit):
2
Which data position to read?
0
SECRET
Data read. Perform another action?
Choose option (1-Write, 2-Read, 3-Exit):
3
Exiting. Thank you!

By following this sequence, you will successfully output the flag `SECRET`.

To retrieve the value of the flag in the provided C code, you need to follow a specific sequence of inputs. The flag is printed when an invalid entry number (0) is provided in the `data_read` function. Here's a breakdown of the steps needed to achieve that: 1. **Write some data**: First, you need to choose the write option and enter some data to store in the system. You can simply input any text for this. 2. **End the write process**: After inputting the data, you will be prompted to enter the length of the data. You should enter a valid length (e.g., the length of the data you just wrote). 3. **Choose the read option**: After writing the data, choose the read option to attempt to retrieve the stored data. 4. **Input an invalid entry number (0)**: When prompted to specify which data position to read, enter `0`. This will trigger the condition in the `data_read` function that prints the flag. ### Example Input Sequence 1. Choose to write data:

1

To obtain the value of the `flag` in the provided C code, you need to follow a specific sequence of inputs to manipulate the program's behavior. The flag is printed when you enter an invalid entry number during the `data_read` function. Here's the step-by-step sequence of inputs to achieve this: 1. **Select the Write option**: - Input: `1` - This will call the `data_write` function. 2. **Enter data for storage**: - Input: `Some data` - This will store the input data into the storage array. 3. **Input the data size**: - Input: `9` (or the length of the input data "Some data") - This specifies the size of the data you just entered. 4. **Select the Write option again (to store more data)**: - Input: `1` - This will call the `data_write` function again. 5. **Enter data for storage**: - Input: `Another data` - This will store another input data into the storage array. 6. **Input the data size**: - Input: `12` (or the length of the input data "Another data") - This specifies the size of the data you just entered. 7. **Select the Read option**: - Input: `2` - This will call the `data_read` function. 8. **Select an invalid data position to read**: - Input: `0` - This will trigger the condition in the `data_read` function that prints the flag. 9. **The output should be the flag**: - The program will print `SECRET`.
