Question

Given the following code fragment: 

if(a==0)

cout<<"Zero";

if(a==1)

cout<<"One";

if(a==2)

cout<<"Two";

if(a==3)

cout<<"Three";

Write an alternative code (using if) that saves on number on compressions. 

Comments

arr[]= {"zero","One","Two","Three"}
if(a>=0 &&a<=3) cout<<arr[a];

compressions reduces Directly to 2

Answer 1

#include<iostream.h>

void main() {

int a;

cout<<"enter a:";

cin>>a;

if(a==0)

cout<<"Zero";

else if(a==1)

cout<<"One";

else if(a==2)

cout<<"Two";

else if(a==3)

cout<<"Three";

else cout<<"other than 0,1,2,3";
