To make the code output the value of the flag, you need to enter an invalid data position when prompted in the data_read function. Here's a sequence of inputs that can make the code output the value of the flag: 1. Choose option (1-Write, 2-Read, 3-Exit): Input: 1 2. Enter data for storage: Input: Hello 3. Input the data size: Input: 5 4. Choose option (1-Write, 2-Read, 3-Exit): Input: 2 5. Which data position to read? Input: 0 (or any non-number input) After these inputs, the code should output the flag value ("SECRET") and then exit.
Below is a student's answer to a question about functionality of the code in C: To make the code output the value of the flag, you need to enter an invalid data position when prompted in the data_read function.

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".

Give me sequence of the inputs that can make the code output the value of the flag. Here is the code: #include <stdio.h> #include <stdlib.h> #include <string.h> #define MAX_INPUTS 10 #define DATA_LENGTH 100 #define ENTRY_LENGTH 5 #define COMMAND_LENGTH 4 static const char* flag = "SECRET"; static char data[MAX_INPUTS][DATA_LENGTH]; static int input_lengths[MAX_INPUTS]; static int inputs = 0; void data_write() { char input[DATA_LENGTH], len[ENTRY_LENGTH]; long length; printf("Enter data for storage: "); // Updated message fgets(input, DATA_LENGTH, stdin); input[strcspn(input, " ")] = 0; do { printf("Input the data size: "); // Updated message fgets(len, ENTRY_LENGTH, stdin); length = strtol(len, NULL, 10); if (!length) puts("Invalid data length, try again."); // Updated message } while (!length); if (inputs >= MAX_INPUTS) inputs = 0; strcpy(data[inputs], input); input_lengths[inputs++] = length; printf("Data stored at position: %d ", inputs); // Updated message } void data_read() { char entry[ENTRY_LENGTH], output[DATA_LENGTH] = {' '}; printf("Which data position to read? "); // Updated message fgets(entry, ENTRY_LENGTH, stdin); entry[strcspn(entry, " ")] = 0; long entry_number = strtol(entry, NULL, 10); if (!entry_number) { puts(flag); fseek(stdin, 0, SEEK_END); exit(0); } strncpy(output, data[--entry_number], input_lengths[entry_number]); puts(output); } int main() { char input[COMMAND_LENGTH]; long command; puts("Welcome to the Data Echo System!"); // Updated message while (1) { printf("Choose option (1-Write, 2-Read, 3-Exit): "); // Updated message fgets(input, COMMAND_LENGTH, stdin); input[strcspn(input, " ")] = 0; command = strtol(input, NULL, 10); if (!command) { puts("Invalid command, enter 1, 2 or 3."); // Updated message } else if (command == 1) { data_write(); puts("Data written.

To make the code output the value of the flag, you need to enter an invalid data position when prompted in the data_read function. Here's a sequence of inputs that can make the code output the flag: 1. Choose option (1-Write, 2-Read, 3-Exit): Input: 1 2. Enter data for storage: Input: Hello 3. Input the data size: Input: 5 4. Choose option (1-Write, 2-Read, 3-Exit): Input: 2 5. Which data position to read? Input: 0 (or any non-number input, e.g., 'a') After entering an invalid data position (0 or a non-number), the code will print the flag ("SECRET") and then exit.
Below is a student's answer to a question about functionality of the code in C: To make the code output the value of the flag, you need to enter an invalid data position when prompted in the data_read function. Here's a sequence of inputs that can make the code output the flag: 1. Choose option (1-Write, 2-Read, 3-Exit): Input: 1 2. Enter data for storage: Input: Hello 3. Input the data size: Input: 5 4. Choose option (1-Write, 2-Read, 3-Exit): Input: 2 5. Which data position to read? Input: 0 (or any non-number input, e.g., 'a') After entering an invalid data position (0 or a non-number), the code will print the flag ("SECRET") and then exit. 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 passes.
Testing if the previous output contains the string student passes: True
