A switch is a statement that is very similar to an if statement. However, a switch allows a condition to have multiple values.The basic structure of the program is as followsSwitch (textval){Case Val:Program codeBreakCase VAL2:Program codeBreakCase VAL3:Program codeBreak......Case VALN:Program codeBreak}A switch is a statement that consists of curly braces, which contain case and break in parentheses.Where C # requires that a case must have a break. A case cannot jump directly to the next case.B
