Rather than the syntax what is the difference in use of if else statement and switch case?

Answer 1

There is difference between ladder if else and switch.

Limitations of switch over ladder if-else
1. The variable expression are not allowed in cases.
Eg. case i+1:

2. Can not test flat expression using switch.
Eg. Switch(x>y)

3. Switch statement must know value inside it during compilation.

4. Can't use for complex comparison.

5. For simple and few expression better to go for ladder if-else because of fast execution and easy to write.

Advantage of Switch:
1. Switch work faster than equivalent ladder if-else.
2. More readable compare to ladder if-else.
3. Management is easy.
4. If large number of compare then go for switch.

Answer 2

You can always translate a switch statement to a chain of if/else, but the opposite is not always true.
