What will be output of the following "C" code?
#include <stdio.h>
void main()
{
int i=10;
printf("%d,%d",++i,++i);
}

A11,12

B12,11

C10,11

D11,10

E12,12

Answer: Option E

Explanation:

It may depend upon compiler too.

Basically when we compile our above C program, C compiler converts C code to Machine code.

so,  that the executable run without having actual source code. C compilers typically try to optimize the output (i.e a.out) so that lesser Machine
code needs to be executed finally. One such optimization is removing
unnecessary Machine code for accessing variable which is not changing
as per Compiler’s perspective.

The gcc option -O enables different levels of optimization. like -O0 can be used to disable the optimization, and if you compile the above program with this option result will be 12 11. There are three level of optimization like -O1, -O2 and  -O3. In that -O3 is highest level of optimization.

the answer will be 12 , 12 in the case when compiler has optimize the code. It keeps value variable "i" in temporary register (cache) at the point it is
requested it will print the value from there instead fetching the current value from storage of i.

In this question as per-increment has been used so that i value changed to 11 than 12, the current value of "i" in cache (temporary register) is 12. as it is not optimize so that it print 12 and 12.

however if you compile code by -O0 it will be 12 11.

gcc -O0 increment.c

if you replace the statement int i = 10; by volatile int i =10 ; (like below ) the above program output will be 12 11.

#include <stdio.h>
void main()
{
volatile int i=10;
printf("%d,%d",++i,++i);
}

Volatile : "volatile" keyword force compile to not optimize this variable. so that each time it will fetch the latest values instead of storing in cache and fetching it from there.


Hope i have explained ... hit like plz....
