Answer Posted / 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.
