Why do we use switch case in C?

In C++, the switch statement is used for executing one condition from multiple conditions. It is similar to an if-else-if ladder. Switch statement consists of conditional based cases and a default case. In a switch statement, the “case value” can be of “char” and “int” type.

How do you end a switch case?

You can use the break statement to end processing of a particular labeled statement within the switch statement. It branches to the end of the switch statement. Without break , the program continues to the next labeled statement, executing the statements until a break or the end of the statement is reached.

How do you use a switch statement?

The “switch” statement

  1. The value of x is checked for a strict equality to the value from the first case (that is, value1 ) then to the second ( value2 ) and so on.
  2. If the equality is found, switch starts to execute the code starting from the corresponding case , until the nearest break (or until the end of switch ).

What is difference between string and char?

char is a primitive data type whereas String is a class in java. char represents a single character whereas String can have zero or more characters. So String is an array of chars. We define char in java program using single quote (‘) whereas we can define String in Java using double quotes (“).

Is default necessary in switch case?

If no default clause is found, the program continues execution at the statement following the end of switch . By convention, the default clause is the last clause, but it does not need to be so.
