Question

consider execution of the following switch statement:

int Enter = 10;

cin >> Enter;

switch (Enter)

{

case 1: Enter = -4;

case 2: Enter = -6;

case 4: break;

case 6: Enter = -8;

break;

default: Enter = -1;

}

What would the value of Enter be after execution of this code if the value read for Enter were 4?

-4,-6,-8 or none

Answer 1

/*

As we are giving 4 as input to Enter value Enter is assigned with 4 so at present, the value of Enter is 4

In switch case, if Enter is 4 we are just breaking the switch so Enter is still 4.

*/

//CODE

#include <iostream>
using namespace std;
int main()
{
int Enter = 10;
cin >> Enter;
  
switch (Enter)
{
case 1: Enter = -4;
  
case 2: Enter = -6;
  
case 4: break;
  
case 6: Enter = -8;
  
break;
  
default: Enter = -1;
  
}
cout << "Enter : " << Enter;
return 0;
}

//OUTPUT
