computing language

compiler should not make any assumption about the variable 
which declared as volatile.

In c u can create variable with name new and delete but not
in c++.

if a structure tag is a datatype of a variable or data
member then it is known as a self referential structure.


for ex
template <class t>

  struct node
   { 
    t data;
    node *link;//here link is a variable which contains data
type of structuretag ie node
    }

whenever a structure is been pointed by the same structure
pointer which is the member of the same structure is called
as self referential structure....


thank u

main()
{
int x,y;
sf("%d,%d",&x,&y);
if(x^y)
pf("not equal");
else
pf("equal");
}

at the level of the language as a storage class persistence 
is defined on ... A program written in C is passed through 
a precompilation phase in which the statements related to 
persistence are converted into their corresponding storage 
system calls.
