Switch-case, on the other hand, is almost similar to the if statement, while in this statement, the cases will determine the execution step. In the case of switch, this always falls in a discrete set of values, and hence, those values can be set up:

int a = 5;
switch (a)
{
  case 4:
     // Do something; 
     break;
  case 5:
     // Do something;
     break;
 default:
     // Do something;
     break;
}

The switch case automatically picks the correct case statement, depending on the value, and executes the steps defined inside the block. A case need to be concluded with a break statement.
