Answer 1

Question a:

Code written using a case/switch construct can always be rewritten using an if/esle construct.

Because in switch case, a variable value is checked with different cases which can also be achieved using if-elseif-else construct.

Eg:

switch(value){

case 1: //statements

case 2: //statements

case 3: //statements

default: //statements

}

The above switch statement code can be rewritten as

if(value==1)

{//statements}

else if(value==2)

{//statements}

else if(value==3)

{//statements}

else

{//statements}

Question b:

Code written using an if/else construct cannot always be rewritten using a case/switch construct.

It can be rewritten in the vice versa case of above explanation i.e.,condition checking is done on a single variable.

But in the case of conditions using multiple variables in different cases in if/else construct cannot be rewritten in switch/case construct.

Eg:

if(value==1)

{//statements}

else if(grade=='A')

{//statements}

else if(value==5)

{//statements}

else

{//statements}

The above if/else construct cannot be rewritten using switch/case construct.
