Accepted Answer

This was an output-based question asked in the C Programming section.
This was an easy question but tricky as well. If you are not clear with C basics.
In this question value of b is pass by value to "func" and hence any local change will not affect the passed value of b in the main function. So the correct answer is Option 1: 20.

Accepted Answer

Ans: option1 
Bcz b variable is passed as value
