Chapter 5: Controlling Program Flow 75The value of expression must be an integer (int, long, or char). The casevalues c1, c2, and c3 must be constants. When the switch statement isencountered, the expression is evaluated and compared to the various caseconstants. Control branches to the case that matches. If none of the casesmatch, control passes to the default clause.Consider the following example code snippet:int choice;cout > choice;switch(choice){case 1:// do “1” processingbreak;case 2:// do “2” processingbreak;case 3:// do “3” processingbreak;}default:cout
