What are the types of linkages?
Answer: Option
Explanation:
External Linkage-> means global, non-static variables and functions.
Internal Linkage-> means static variables and functions with file scope.
None Linkage-> means Local variables.

When x=2,
if z=x++ + ++x.
Then z=?
if z=x++ + ++x.
Then z=?

What is linkages? how it affects the c program in terms of memory or storage class?

@Moumita.
When x=5 then,
Z=++x + ++x;
Is printing 14 not 13.
I checked it guys,
x = 7 at last, Because a value of a variable(x) vl hold the latest value that's being stored in the memory(i.e) 7.
So z = 7+7 = 14.
When x=5 then,
Z=++x + ++x;
Is printing 14 not 13.

13 because here first x = 5.
Then ++x = 6(pre increment).
Now x = 6.
Then ++x = 7.
So z = ++x + ++x.
z = 6+7 => 13.
Then ++x = 6(pre increment).
Now x = 6.
Then ++x = 7.
So z = ++x + ++x.
z = 6+7 => 13.

Guys please check this once more.
When x =5 then,
Z=++x + ++x;
Is printing 13 not 14....
So what is the actual explanation?

Z=++x + ++x;

@Aliya.
C compiler does parsing (reading and evaluating) from left to right of each line of code. That is purely related to compiler design(cd) topic for further details refer cd of C language.

@Praveen:
Why the evaluation is done from the right most i.e; x++.
++x=3; the value of x=3.
x++=3; we do not increment here since its a post inc.
++x + x++ = 6?
Why aren't we considering pre inc first?

Give details of linkages & when they are used?

@Praveen.
Why x++ value remains 2?
Why it is not incremented by 1?
Why x++ value remains 2?
Why it is not incremented by 1?
