Guys please check this once more.

When x =5 then,

Z=++x + ++x;

Is printing 13 not 14....

So what is the actual explanation?

Kavitha said:   1 decade ago
#include<stdio.h>
int main()
{
int x=3;
int z;
z=++x + x++;
printf("%d",z);
}

It gives the output 9,how?

Mounika said:   1 decade ago
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.

#include <stdio.h>
int main()
{
int i = 2;
int j = ++i + i;
printf("%d\n", j);
}

Output = 6.

Pre increment - increment the value and then use it.

Post increment - use the value and then increment.

Pre increment - increment the value and then use it.

Post increment - use the value and then increment.

Pre-increment - increment the value and then use it.

Post-increment - use the value and then increment.

Can anyone tell me the difference between static and non-static variables? and also about linkages.

Anitha said:   1 decade ago
How can we print a string without using printf() and any other functions like puts() & get() ?

Nali srikanth said:   6 years ago
Static variable is a fixed.
Non static variable can be changed.
None linkage means local variable.
