switch case comp c++ code example

Example 1: switch c++

switch(expression) {
   case 1:
      //equivalent to if(expression == 1){//do someting...}
      //do something...
      break; 
    //if case 1 is true the rest of the statments arn't 
    //evaluated because of the break
   case 45:
      //equivalent to else if(expression == 45){//do someting...}
      //do something...
      break;
    
   // you can have any number of case statements and default has to be last
   default :
      // equivalent to else{//do someting...}
      //do something...
}

switch(expression) {
   case 1:
      //equivalent to if(expression == 1){//do someting...}
      //do something...
   case 45:
      //equivalent to if(expression == 45){//do someting...}
      //do something...
   default :
      //always runs if there are no breaks in any of the cases
      //do something...
}

Example 2: how to make a switch case statement in c++

#include <iostream>
using namespace std;
int main(){
   int num = 5;
   switch(num + 2) {
      case 1: 
        cout << "Case1: Value is: " << num << endl;
      case 2: 
        cout << "Case2: Value is: " << num << endl;
      case 3: 
        cout << "Case3: Value is: " << num << endl;
      default: 
        cout << "Default: Value is: " << num << endl;
   }
   return 0;
}
