Basically,Switch case work as decision making statement in C and C++ language.
Syntax-
switch(variable)
{
case value1:
body;
case value2:
body;
.
.
.
}
Now we can guess number is 1,2 or 3.
program:
#include < iostream>
using namespace std;
class myclass
{
public:
//guess the number
int guess(int a)
{
switch(a)
{
case 1:
cout<<"Number is 1";
break;
case 2:
cout<<"Number is 2";
break;
case 3:
cout<<"Number is 3";
break;
default:
cout<<"Undefined";
}
}
};
int main()
{
int n;
cout<<"Enter any number";
cin>>n;
myclass obj;
obj.guess(n);
return 0;
}
Enter any number
2
Number is 2
Enter any number
34
Undefined
