#line
Define arbitrary line numbers for the source lines.
Using the #line directive, you can specify an arbitrary line number at any point.
The compiler then uses that line number for subsequent counts.
#include <stdio.h>
main()
{
printf("A\n");
#line 100
printf("B\n");
printf("C FILE %s LINE %d\n", __FILE__, __LINE__ );
#line 200
printf("D\n");
printf("E\n");
}A
B
C FILE line0.c LINE 101
D
E
