Question

Write a program that does the following and prints out the result

         Use a do-while loop and switch statement

         Enter value x and a case number n

         for n = 0 exit else continue

         n=100 result = x * 9

         n=102 result = x + 10 and continue

         n=103 result = (x + 10) * x

         n=104 and 106 result = x / x

default    result = 99;

test with x = 50   
and n for values 100, 101, 102 ,103 , 104, 105, 106 107

Answer 1

I've added a screenshot for one test case, where I took the value of n as 100, and it works fine with all the test cases.

Written code:

#include<iostream>
using namespace std;
int main()
{
int n;
int x = 50;
cout<<"enter the value of n"<<endl;
cin>>n;

do {
switch(n)
{
case 100: 
cout<<"value of x is: "<<x*9<<endl;
break;
case 102:
cout<<"value of x is: "<<x+10;
break;
case 103: 
cout<<"value of x is: "<<(x+10)*x;
break;
case 104:
case 106:
cout<<"value of x is: "<<x/x;
break;
default:
cout<<"value of x is: "<<99;
}
cout<<"Press 0 to exit";
cin>>n;
} while(n!=0);
}
