In C, #line is used as a preprocessor to re-set the line number in the code, which takes a parameter as line number. Here is an example for the same.
#include <stdio.h> /*line 1*/
/*line 2*/
int main(){ /*line 3*/
/*line 4*/
printf("Hello world\n"); /*line 5*/
//print current line /*line 6*/
printf("Line: %d\n",__LINE__); /*line 7*/
//reset the line number by 36 /*line 8*/
#line 36 /*reseting*/
//print current line /*line 36*/
printf("Line: %d\n",__LINE__); /*line 37*/
printf("Bye bye!!!\n"); /*line 39*/
/*line 40*/
return 0; /*line 41*/
} /*line 42*/
