Question

4. Write a function that returns a value to the main program illustrated below. In the function, the variable passed by the main program needs to be evaluated using a switch statement. The value returned is determined by the case that it matches. (10 points) If value is: return 10 return 20 3 return 30 Anything else, return 0 Main program: #include <iostream> using namespace std; int findValue (int); int main) { Int numb, retvalue cout << "In Enter a number: " cin > numb retvalue findValue (numb); cout << "In The value returned is << retvalue<< endl: return 0

Answer 1

#include<iostream>
using namespace std;

int findValue(int);

int main()
{
int numb,retvalue;
cout<<"\nEnter a number : ";
cin>>numb;
retvalue=findValue(numb);
cout<<"\nThe value returned is "<<retvalue<<endl;
return 0;
}

int findValue(int value)
{
int retValue;

switch(value)
{
case 1:
retValue=10;
break;

case 2:
retValue=20;
break;

case 3:
retValue=30;
break;

default:
retValue=0;
break;
}

return retValue;
}
