There are three important things to know about the switch statement: • The switch differs from the if in that switch can only test for equality, whereas if can evaluate any type of relational or logical expression. • No two case constants in the same switch can have identical values. Of course, a switch statement enclosed by an outer switch may have case constants that are the same. • If character constants are used in the switch statement, they are automatically converted to integers.

Switch may be more readable, rather than having a really large if-else-chain with just equality checks, but in my opinion, switch isn't that important, you'll be fine using if statements

No, it isn't. Although it has a really awkward syntax

No, switch can only test if a value equals to something, it can't do comparison.

Is that possible to implement the following code using switch #include <stdio.h> int main() { int score = 89; if (score >= 90) printf("%s", "Top 10% \n"); else if (score >= 80) printf("%s", "Top 20% \n"); else if (score > 75) printf("%s", "You passed.\n"); else printf("%s", "You did not pass.\n"); }
