Visual Studio functions are warned about security and how to modify them

1. When we use the _ ITOA function today, the problem of egg pain is already Microsoft's.

 

 

2. How can this problem be solved?

Add a sentence in the first line: # DEFINE _ crt_secure_no_warnings // disable the security check.

The Code is as follows:

1 # DEFINE _ crt_secure_no_warnings 2 # include <stdio. h> 3 # include <stdlib. h> 4 int main () 5 {6 int num = 65543; 7 8 printf ("decimal = % d, hexadecimal = % x, octal values: = % O \ n ", num); 9 10 char STR [32]; 11 _ ITOA (Num, STR, 2 ); 12 13 printf ("binary = % s", STR); 14 15 getchar (); 16}
