Answer / mahesh
call by value
int fun(int a,int b);
int fun(int p,int q)
{
temp=p;
p=q;
q=temp;
}
call by reference
int fun(int &a,int &b);
int fun(int *a,int *b)
{
temp=*a;
*a=*b;
*b=temp;
}
call by value is with values n call by ref with adresses n
pointers...

Answer / raju
Call by Value: C support the call by value, where the caller
pass the value to the function and the updates on the
function will not effect on the caller.
Call by reverence: Here will pass the reference of the
variable to function, the update on the function variables
will effect on the caller.
