Compile as followsCode:

 
# Include <stdio. h> intmain (void) {int I =-10; if (I <0) {exit (1) ;}return 0 ;}

The compilation information is as follows:

$ GCC demo. c
Demo. C: In function 'main ':
Demo. C: 9:Warning: incompatible implicit declaration of built-in function 'delete'

 

 

 

The error occurs because it does not contain the corresponding file information. You can try the following solutions:

Add the # include <stdlib. h> header file

"★Example

# Include <stdlib. h> # include <stdio. h> intmain (void) {int I =-10; if (I <0) {exit (1);} return 0 ;}
Use the [-fno-builtin-exit] Option to disable warnings during compilation.

"★Example

$ Gcc-fno-builtin-exit demo. c
$

 

 

Use the system to define constants for better portability ★ Example
 
# Include <stdio. h> # include <stdlib. h> intmain (void) {int I =-10; if (I <0) {exit (exit_success);} return 0 ;}
