Ptr is a constant pointer to constant integer. Both the values cant be changed.
eg:
const int a=10;
const int *const ptr=&a;
int b=20;
const int *const ptr=&b;//error
a=25;//error

Its simple.
1. do calculate the sum of numbers from 1 till 100. is about (1+100)*(100/2)=5050
2. iterate and summarize all elements of container (array).
3. each number is unique in the container, so the difference between 5050 and the sum (from point 2) gives us an answer.

What is function linkage mechanism? Can inline function be used at run time? Why or why not?

sunil

• Jul 26th, 2014

Inline functions body are made to expand at compile time. So they are expanded at the time of compilation, since compiler decides whether the function is going to be inline or not.

What is Static Polymorphism? Give its syntax and simple example.

rdl

• Dec 28th, 2014

The call to a function is resolved at compile time. Eg., function overloading and templates.

Youssef Arbach

• Dec 12th, 2014

Static polymorphism could be seen also with Templates, since the selection of the write function is done at compile time. Usually with inheritance (and call-by ref sure) polymorphism is dynamic, unless it is a call by-value, then there would be no morphism at all.
