CSCI 101: Fundamentals of Computer Programming Lab 7: More Conditional & Relational Operators Fall 2005 Introduction Another alternative to using if else statements are switch statements. Similar to if else statements, the switch statement also evaluate an expression, and branches off to multiple sections of the program depending on that expression. However, the advantage of the switch statement becomes apparent when there are multiple alternatives to the condition, instead of the default true/false conditions that we are used to in if statements. The syntax of a switch statement is below: switch (expression) { case (constant 1): task 1; … break; case (constant 2): task 2; … break; default: task 3; … break; } When the compiler reaches the start of the switch statement, it will evaluate the value of expression. It will then look for the its corresponding case, and evaluates the task that follows it until it encounters the break statement. It will run the default case if no matching cases are found. Both if else and switch statements have their advantages and disadvantages for different cases. They somewhat complement each other relatively well and it is important for programmers to learn when to use which structure for more elegant code. However, it is important to note that both structures are capable of doing what the other does.
