The code is as follows:

 # include "stdio.h" 
Int main (void) {
Char [10] p; 
if(! The fgets (p, 5, stdin)) 
; 
return 0; 
} 

CodePudding user response:

Read the fgets failure it returns NULL, NULL is equivalent to zero is equivalent to the false, plus! (not) invert, means to read the meaning of success,
