What is switch case explain with example?
Switch Case Example in C A switch construct is used to compare the value stored in variable num and execute the block of statements associated with the matched case. In this program, since the value stored in variable num is eight, a switch will execute the case whose case-label is 8.
Can we use if statement in switch case in C#?
To begin, we will type the switch statement followed by the variable being tested inside parentheses as you can see in Fig. 3. Next, a series of case s control the execution flow based on the value of that variable. Each case ends with the break keyword, which tells the program to exit the switch block.
How does a switch statement work in C#?
The switch statement evaluates the expression (or variable ) and compare its value with the values (or expression) of each case ( value1 , value2 , …). When it finds the matching value, the statements inside that case are executed.
Is switch case faster than if?
As it turns out, the switch statement is faster in most cases when compared to if-else , but significantly faster only when the number of conditions is large. The primary difference in performance between the two is that the incremental cost of an additional condition is larger for if-else than it is for switch .
Is default mandatory in switch case C#?

How do you write a switch statement?

Which is better switch or if-else in C#?
The results show that the switch statement is faster to execute than the if-else-if ladder. This is due to the compiler’s ability to optimise the switch statement. In the case of the if-else-if ladder, the code must process each if statement in the order determined by the programmer.
