Question
What will be the last 5 lines of the output of the command gcc -E on this code?
#include <stdlib.h>
int main(void) {
NULL;
return (EXIT_SUCCESS);
}
Solution
The gcc -E command in Linux is used to stop after the preprocessing stage; this means it will expand all the macros in the program. The #include <stdlib.h> line is a preprocessor directive that includes the standard library in the program. The NULL and EXIT_SUCCESS are macros defined in this library.
The last 5 lines of the output of the command gcc -E on this code would be the expanded version of the macros NULL and EXIT_SUCCESS, along with some additional lines added by the preprocessor. However, the exact output can vary depending on the system and the specific version of the standard library.
Please note that the actual code and the command should be run on a Linux system to get the exact output.
