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.

What is the difference between non static variable and local variable?
Shiny said:

Why external linkage means global, non static, functions?
Why internal linkage means static variables, functions with filescope?
Why none linkage means local variables?
Please give clear information about those three.

Static variable are the variable which allocate the memory as well as program start and they create only one copy for more then object.

Its too late and ignore if not but it shouldn't be like this:
If x = 2.
z = x++ + ++x // here because x = 2, value 2 is assign to x (value 2 stored to perform overall function) n stored after that it'll increment by 1.
=> z = (2) ++.
That will 3. Till z = x++ value of x is 3.
After that z = 3 + ++x //till here x = 3.
So further by pre-increment 3 will incremented by 1 value will be 4. So z = 2 + 4 = 6.
If x = 2.
z = x++ + ++x // here because x = 2, value 2 is assign to x (value 2 stored to perform overall function) n stored after that it'll increment by 1.
=> z = (2) ++.
That will 3. Till z = x++ value of x is 3.
After that z = 3 + ++x //till here x = 3.
So further by pre-increment 3 will incremented by 1 value will be 4. So z = 2 + 4 = 6.

Can anyone explain the answer of this: z = (x++ + ++x)x = 2. And z = (++x + x++)x = 2.

What is meant by external linkage?

You must initialize the i with a value because it will take a garbage value by default.

Why we use return in program?
Tiger said:

@Karthick we use the return in the program because the return any value for example.
#include<stdio.h>
int main()
{
int i=5;
return i;
}
Output of the above program is 5 because it will be return the value of the i.
#include<stdio.h>
int main()
{
int i=5;
return i;
}
Output of the above program is 5 because it will be return the value of the i.

#include<stdio.h>
int main()
{
int x=3;
int z;
z=++x + x++;
printf("%d",z);
}
It gives the output 9,how?

{
int x=3;
int z;
z=++x + x++;
printf("%d",z);
