Use fgets instead: fgets(temp, sizeof(temp), stdin); gets is deprecated because it's dangerous, it may cause buffer overflow.
If you want to read a string from standard input, you can use the gets function, the name of which stands for "get string". However, this function is deprecated -- that means it is obsolete and it is strongly suggested you do not use it -- because it is dangerous.
To avoid Buffer Overflow, fgets() should be used instead of gets() as fgets() makes sure that not more than MAX_LIMIT characters are read.
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.
Use fgets instead:
fgets(temp, sizeof(temp), stdin);
gets is deprecated because it's dangerous, it may cause buffer overflow.
