Using scanf_s instead of the scanf good ~ VS2017 don't support the scanf, but using scanf_s security function

using scanf_s instead of the scanf good ~ VS2017 don't support the scanf, but with the safety function scanf_s

The scanf in VS2017 is considered unsafe?

For, such as using the scanf enter a "123456" to the char [2], the scanf will cross cover, so using scanf_s instead of, have a length of control parameters, the other can also be VS SDL to check off, you can use the scanf

Thank god's help, I go to the operation

CodePudding user response:

Is not only the scanf, like sprintf, memcpy these functions will be considered to be unsafe, so the introduction of the sprintf_s, memcpy_s function like this, of course you can choose to not safe to ignore this error and in the code plus the # pragma warning (of which: 4996) is also a kind of method to filter out the mistake
