switch case c++ string code example

Example 1: c++ switch case statement

switch (n)
{
    case 1: // code to be executed if n = 1;
        break;
    case 2: // code to be executed if n = 2;
        break;
    default: // code to be executed if n doesn't match any cases
}

Example 2: switch statement c++

switch(expression) {
   case constant-expression  :
      statement(s);
      break; //optional
   case constant-expression  :
      statement(s);
      break; //optional
  
   // you can have any number of case statements.
   default : //Optional
      statement(s);
}

Example 3: 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;
}

Example 4: c++ switch string

switch(str2int("my string"))
{
  case str2int("my string")):
    {
    }
    break;
}

constexpr unsigned int str2int(const char* str, int h = 0)
{
    return !str[h] ? 5381 : (str2int(str, h+1) * 33) ^ str[h];
}

Example 5: 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;
   	 }
}

Example 6: switch in c++

switch (variable) {
  case 1:
    // code here
    break
  default:
    // code here 
    break
