What do you mean a condition differentiate if else and if else if ladder statements?
If – else – if ladder Statement The if-else-if ladder statement executes one condition from multiple statements. The execution starts from top and checked for each if condition. The statement of if block will be executed which evaluates to be true.
When should switch be used instead of if else statements?
Use switch every time you have more than 2 conditions on a single variable, take weekdays for example, if you have a different action for every weekday you should use a switch.

What are differences between switch statement and if else if statement control structures by using the aid of flowchart s explain the differences?
In the case of ‘if-else’ statement, either the ‘if’ block or the ‘else’ block will be executed based on the condition. In the case of the ‘switch’ statement, one case after another will be executed until the break keyword is not found, or the default statement is executed.
How can the if statement be written as a switch statement?
1 Answer. Any condition within a if() statement evaluates to either 0 or 1(it is actually any value other than 0). So writing it in switch() statement is equivalent to writing switch(a) , where a can be either 1 or 0. So, you are absolutely correct!
How do you convert a switch statement?

What is the difference between else if ladder and switch case?
1 In else if ladder, the control goes through the every else if statement until it finds true value of the statement or it comes to the end of the else 2 The switch case is more compact than lot of nested else if. 3 The use of break statement in switch is essential but there is no need of use of break in else if ladder.
What is the advantage of switch statement over if-else?
In many cases a switch statement will perform better than an if-else chain. The strict structure makes it easy for an optimizer to reduce the number of comparisons that are made. This is done by creating a binary tree of the potential options.
What is the use of switch statement in Java?
In case of a switch, we create jump table on compile time only selected case is executed on runtime. In this case, we do not create a jump table and all cases are executed at runtime. If a program is large we use the switch statement. If a program is large then program structure will be more complex.
What is the use of switch case in C programming?
For decision making in C programming, the statements such as if, if..else, else if, switch case etc. have defined in the standard C library. In case of multi-conditional processing, basically there come two statements in the choice of a programmer; they are switch case and else if ladder.
