Question
If you have the following C++ code segment:
int x;
cin>>x;
switch (x)
{
case 1:cout<<"x is 1 ";
case 2:cout<<"x is 2 ";break;
default:cout<<"value of x unknown ";
Choose the correct C++ code segment that produces the same output of the above C++ oode segment:
int x;
cin>>x;
if (x==1)
cout<<"x is 1 ";
if (x==2)
cout<<"x is 2 ";
a)
if ((x=1)||(x!=2))
cout<<"value of x unknown ";
int x;
cin>>x;
if (x==1)
cout<<"x is 1 "<<"x is 2 ";
if (x==2)
cout<<"x is 2 ";
b)
if ((x=1)&&(x!=2))
cout<<"value of x un known ";
int x;
cin>>x;
if (x==1)
cout<<"x is 1 ";
if (x==2)
c)
cout<<"x is 2 ":
if ((x=1)&&(x!=2))
cout<<"value of x unknown ";
int x;
cin>>x;
if (x==1)
cout<<"x is 1 ";
d)
else
if (x==2)
cout<<"x is 2";
el se
cout<<"value of x un known ";
