Difference Between if-else and switch

In this post, we will understand the difference between if-else statement and ‘switch’ statement.

If-else

• Depending on the expression inside the statement, output would be generated.

• It uses multiple statements for multiple choices.

• This statement tests for equality.

• It can be used to test logical expressions.

• It can evaluate integer, character, pointer, floating-point type and boolean type.

• Just one of the ‘if’ or ‘else’ statement gets executed.

• If the condition inside the ‘if’ statement is false, then the ‘else’ statement is executed if it has been created.

• It is tough to edit if-else statement, especially if it is nested.

Switch

• The statement that needs to be executed is decided by the user.

• It uses a single expression to work with multiple choices.

• It only tests for equality.

• It evaluates a character or an integer value.

• It is easy to edit, since it can be identified easily.

• It executes one case after another until a break statement is encountered.

• The ‘break’ statement terminates the switch statement.

• If the condition inside the switch statement doesn’t match any case, the default statement is executed if it has been created.
