How a switch statement works internally. That is how does it find which does it need to execute?

Pallav Malu
Switch is especially useful as check point for multiple conditions. Syntax: Switch(condition) { case 1: logic ;break; case 2 :logic; break; default : logic; } .switch statement checks condtion or choice and look for right case and execute the logic and then break the execution flow. if it did not find the any matched case , it will execute default block.
ex: int day=1;
switch(day){
case 1:
print("Monday");
break;
case 2:
print("Tuesday");
break;
case 1:
print("Wednesday");
break;
case 1:
print("Thursday");
break;
case 1:
print("Friday");
break;
case 1:
print("saturday");
break;
Default:
Print("Sunday");
}
result of condition is true or false we use if condition
When there are more than two options we use switch statement
compiler checks the case statement from top to down any case matches with the conditions it executes the blocks until break encounters other wise it edecutes default statements
