C++ Switch Statements

The switch statement is almost the same as an “if statement”. The switch statement can have many conditions. You start the switch statement with a condition. If one of the variable equals the condition, the instructions are executed. It is also possible to add a default. If none of the variable equals the condition the default will be executed. See the example below:

Switch statement will be evaluated one time only
Case is used to specify the condition
break is used to exit the switch
default is used to perform default execution if not met within all cases

default is not required but can be used to set alternate executions if not met within all previous cases.

Example of C++ Switch Statements

#include <iostream>
using namespace std;

int main() {
  int number = 1;
  switch (number) {
    case 0:
      cout << "Number is 0";
      break;
    case 1 :
      cout << "Number is 1";
      break;
    default:
      cout << "not 0 or 1";
  }
  return 0;
}

Output

Number is 1
