Difference Between if-else and switch (Full Details)

Conditional statements include “if-else” and “switch.” The main distinction is that a switch dispatches to the case in question right away, usually by an indexed jump, rather than needing to evaluate every condition as in an if-else chain, which causes code at the end of the chain to be accessed more slowly than code at the beginning.

In both table and point form, the lesson shows the main difference between If-else and switch case selection statements. Let’s find out:

if else and switch

What Is the If-else?

If-else is a programming language that lets you make a conditional statement that runs different sets of statements depending on whether an expression is “true” or “false.”

If the value of the expression is not zero, it can be “true,” and if it is zero, it can be “false.” The else statement can be a single statement or a group of statements.

Most of the time, the expression in an if statement is made up of integers, pointers, characters, and floating-point numbers. In an if-else statement, the else statement is often not needed.

Example of If-else Statement:

Main Features of If-else Statement

  • If support statements for true part only
  • If-else support statements for true and false
  • If the test expression is true then a true block statement is executed otherwise
  • Either the true block statement or false block statement is executed every time

What Is the Switch Case?

The switch case statement is a piece of programming language that compares the value of a variable to its different causes.

If the expression evaluates to a number or a constant, the evaluation can be based on whether or not they are the same. If the expression is compared to a constant, a match must be found.

In a switch statement, a break statement is usually not needed. But if there is no break statement, the code will keep running until the switch statement is done.

Most of the time, a switch statement uses keyboard commands, and most of the time, an expression only has one expression.

Example of Switch Case Statement

Main Features of the Switch Case

  • Multiple-way decision
  • Tend to test whether the expression matches any of the constant values
  • The expression can be an integer or character expression
  • Each case is labelled by either one or two integers
  • There must be the value of all expressions
  • If the case matches the value of the expression then execution starts

Key Difference between If-else and Switch Case

  • With an if-else statement, you can choose between two options. With a switch case statement, you can choose between more than two options.
  • If-else values depend on what can’t be changed, while switch case values depend on what the user chooses.
  • If-else statements are used to set up a linear search, while switch case statements are used to set up a binary search.
  • When the nested if-else statement is used, it can be hard to change the if-else statement, but it is easy to change the switch case statement.


  • Both are used to make programs work.
  • Both are used to figure out what conditions are like.
  • Both tend to be the same, except for the way they are shown
