SWITCH:-

                    when we needseveral if statements,it is better to use switch statement. in other words, switch is a variation of if statement which performs multiway branching.

  • syntax:-

switch(expression)
{
case value:
                    statement(s);
                     break;
case value:
                       statement(s);
                        break;
default:
                     statement(s);
                      break;
}
switch is key word begins switch construct.
break breaks exection of perticular statement.

  • code:-


#include<iostream.h>
void main()
{
int k;
cout<<"press any key"<<endl;
cin>>k;
switch(k)
{
case 1 :  cout<<"one"<<endl;
              break;
case 2 : cout<<"two"<<endl;
             break;
case 3:cout<<"three"<<endl;
           break;
default : cout<<"please enter the valid entry"<<endl;
             break;
}
}
