Fix strcpy Buffer Overflow: C Solutions

There are several methods that can be used to address the buffer overflow issue caused by strcpy.

1. Use a safer function: you can replace the strcpy function with the strncpy function, which limits the length of the copied string to prevent overflow.
2. Manually check the length of the string: Before using the strcpy function to copy a string, it is possible to manually check the length of the source string to ensure that there will be no overflow.
3. Use dynamic memory allocation: use functions such as malloc to allocate enough memory to accommodate the string being copied, in order to avoid issues with overflowing fixed-size buffers.
4. Utilize secure function libraries: Some secure function libraries like SafeStr library offer safer string manipulation functions that can replace standard string manipulation functions, thus preventing buffer overflows.
5. Programming conventions and best practices: when writing code, adhere to programming conventions and best practices to avoid using unsafe functions or methods, ensuring the security and stability of the program.
