What we do to remove error??
#include<stdio.h>
extern int var;
main()
{
var=10;
return 0;
}*
Answer :
*Linker Error : Undefined reference to 'var'
*
Explanation*:
extern storage class in the following declaration, extern int var; specifies
to the compiler that the memory for i is allocated in some other program
and that address will be given to the current program at the time of
linking. But linker finds that no other variable of name var is available
in any other program with memory space allocated for it. Hence a linker
error has occurred .
*soution :* to remove error we have to eliminate the extern keyword before
the 'int' at the declaring the var variable
