and you type in more than 10 characters when the program is run, you will overflow the buffer, causing undefined behaviour. The gets() function has no means of preventing you typing the characters and so should be avoided. Instead you should use fgets(), which allows you to limit the num...
The gets() function provides no support to prevent buffer overflow if large input string are provided. It is defined in <cstdio> header file. Note: Avoid using the gets() function as it can be dangerous for the program. This function was deprecated in C++11 and removed from C++14. gets...
In C, the standard functiongets()was removed in the latestC11standard. While this function can be used for string input, itshould be avoided at all costs. It is not a safe method for inputting strings because it writes to memory continuously as you type, making buffer overflows a common...

The 'gets' function is a vital input function in many programming languages, particularly within the C programming language. Despite its simplicity, 'gets' carries some potential risks and is often criticized for its vulnerability to buffer overflow attacks. However, understanding the fundamentals and...
