CodePudding user response:

scanf_s () is used to read the string, you must provide a number to indicate how many characters, most read in order to prevent overflow,
Scanf_s (" % s ", buf, 5);//says most read four characters, because buf should put [4] '\ 0'

I then display an error

CodePudding user response:

Use the scanf is bad

CodePudding user response:

reference 3/f, 5250 response:

with the scanf bad?

VS complains

CodePudding user response:

Scanf_s is a function of v need, compared the scanf is high safety, but need to pay attention to the % c, % s, you need to specify the length that is some difference between scanf_s and the scanf
