gets (buffer)//function to limit the length of the input is not
//so there will be warnings in vs with gets This function or variable may be unsafe.

Gets_s (buffer size)//which is allowed to enter the second parameter length
//here is the size of the length of the allocated buffer 1 just right, otherwise for '\ 0' automatically allocate space will overflow,

See the code below:


#include
Int main (void)
{
Char buffer [21].//20 chars + '\ 0'
Gets_s (buffer, 20);//written after the 21st, when entering 21 characters enter, automatically add '\ 0', will require allocation of storage space
Printf (" Your input was % s \ n ", buffer);
system("pause");
return 0;
}

This is not the length of the problem, the visual stdio display gets and get_s are said to find identifier, I know \ 0 to account for a memory characters

CodePudding user response:

Vs does not support the gets function, get_s the function, is get (the function name, length), the mean?

CodePudding user response:

Sorry, wrong number then ~ ~

Is gets_s (), vs prefer a more secure

CodePudding user response:

refer to 7th floor and 蘤 old crepe reply:

sorry, wrong number then ~ ~

Is gets_s (), vs like to use a more secure

But I knock on get_s (STR, 225) is an error

I've learned that knock gets_s less an s, and the scanf (% s) is also similar, thank you,

CodePudding user response:

Under the vs gets replaced by gets_s, replace it.

Anything else gets_s, post

CodePudding user response:

make fun of the reference to the tenth floor response:

vs gets be gets_s replaced, replace it.

Gets_s still have what problem, post

B: no, thank you, will continue to work hard

Uh huh, understand, and finally have \ 0 to account for a character
