Answer / astha biswas
there are some key-words like class , new etc which can be
used as identifiers in c. so if we save program in .c using,
new as an identifier, it will not show any error; but if we
save the same program in .cpp, it will show error as new is
an operator in c++.
EX:
#include<stdio.h>
#include<conio.h>
void main()
{
int new;
clrscr();
new=3;
printf("%d",new);
}
if we execute this program in .c, output will be 3.
but if we execute this program in .cpp; then it will show 2
errors.
1. declaration terminated incorrectly.
2. lvalue required.

identifiers in c. so if we execute the program in .c it will
not show any error, where as if we execute the same program
in .cpp , it will show error.
