Q2. Given the following code fragment
i.) What output does the above fragment produce?
ii.) What is the effect of replacing ++ch with ch+1?
ii.) ++ch not only replaces itself with ch+1 i.e., 21 but also increments the value of ch i.e., after ++ch the value of ch is 21. Whereas ch+1 will onlu print the incremented value i.e., 20+1=21; it will not increment the value of ch. Therefore , after replacing ++ch with ch+1, the output of the program will be:
