Answer 1

Arthur you have not done initialization of all three int variable of for loop...also your test should be as below :
x[i]+x[i2]+x[i3]

Answer 2

Ketan Lalcheta Yeah, i totally forgot this...
Do you have any idea about why this happened?

Answer 3

Ketan Lalcheta Noww its showing no output...

Answer 4

Arthur any uninitialized variable, if not static, gets random value by default.. and additionally, you were not adding char from char array but int only to char

Answer 5

Ketan Lalcheta [not to distract, just trivia]
Uninitialized variables get whatever is in memory at the time. This is not necessarily random, and may even be usefully deterministic.
It's still abnormal as an initializer though. :)

Answer 6

Damn!!
