If you write them separately then all the if statements must be executed regardless off which character is found i.e. wasting processing time.You can chain these statements forever, but the Arduino case statement is better choice if you have to do lots of tests (as it is more compact). ...

With the braces in place, adding more statements within the braces would work as expected: if (a == 1) { printf("One!\n"); doSomething (); printf("Done.\n"); } This is something that was drilled in to my brain at a position I had many years ago, and it makes great sense....
Arduino - If statementPrevious Quiz Next It takes an expression in parenthesis and a statement or block of statements. If the expression is true then the statement or block of statements gets executed otherwise these statements are skipped.Different forms of if statement...
