switch ... cpp 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: switch case c++

// Transfers control to one of the several statements, depending on the 
//value of a condition.
switch (variable or an integer expression) {
     case constant: {
     	//C++ code
    	 break;
     }
     case constant: {
     	//C++ code
     	break;
     }
     default: {
     	//C++ code
     	break;
   	 }
}
